ANNOUNCEMENTS AND RESEARCH NOTES
1.01 The power of seeds
(A SeedQuest editorial by
Dr. Norman E. Borlaug, Father of the Green Revolution, Nobel Peace Prize
Laureate)
During my lifetime, seed technology has been the catalyst that
has averted mass starvation on planet Earth. At today’s 6.4 billion, the world’s
population is four times the 1.6 billion people who lived when I was born in
1914. How many more can the earth feed without destroying the forests and
wildlife habitat? The answer hinges on the extent of a continuing stream of
ever-more-powerful seeds, based on focused research, until population
stabilizes.
Of course, we all know that to stay ahead of the “population
monster” requires more than seeds alone. It requires essential policy changes at
the highest levels of governments plus improved production technologies: mineral
was well as organic fertilizers, better tillage practices, more-efficient
irrigation, and weed control. But, without the catalystthe power of
seedsbetter policies and production technologies will not be enough.
Let me describe a few examples of positive results from focused
research.
I first started serious work on seed technology in 1944 as a
Rockefeller Foundation scientist with the cooperative Government of
Mexico-Rockefeller Foundation agricultural research program. Even with imported
foodgrains at the time, many Mexicans were hungry. Based on the wheat and maize
(corn) varieties that we developed, and while population continued a brisk
increase, Mexico became self-sufficient in foodgrains by the mid-1950s.
In the mid-1960s, India and Pakistan were experiencing hunger, and two
provinces in northeast India suffered famine, even while millions of tons
annually of food aid, mostly wheat, were imported. Malthusian thought was
re-awakening. Two widely read books at the time contended, in effect, “Let’s
write off India, it’s hopeless; let’s only provide our food aid to countries
that have a chance.” With the power of the high-yielding seeds and production
technologies that we introduced, together with improved policies, Pakistan in
1968 and India in 1974 became self-sufficient in foodgrains and they have
essentially remained so.
Though few people outside the country knew it,
China during the Cultural Revolution experienced widespread hunger and famine.
Many millions starved. At the time of my first trip to China, in 1974,
universities were closed, food was rationed, things were miserable. On my more
than 12 trips, I witnessed remarkable progress. Although population has
increased by nearly 50 percent, to 1.3 billion, most Chinese today are well fed
and enjoy a much higher standard of living, thanks to the power of seeds as the
catalyst. In the early 1970s, China acquired from Pakistan some of our “Mexican”
short-strawed, high-yielding wheat seeds. China also benefited from improved
varieties of rice provided by the International Rice Research Institute in the
Philippines. But China’s overall success resulted from sound national research
that provided a continuous stream of better seeds and production technologies,
accompanied by a set of policies that support increased production.
The
positive experiences in Mexico, India, Pakistan and China result, largely, from
the catalytic power of three seeds: wheat, rice and maize. Many other countries
of Asia, the Middle East and Latin America also benefited from these improved
seeds. But, what about Africa?
Sub-Saharan Africa is my greatest worry.
In most of the area, maize is more important than either wheat or rice.
High-yielding, disease-resistant quality protein maize (QPM), based on research,
is an important development for many African families who have little milk, eggs
or meat because of animal diseases and poverty. The protein quality of QPM is
close to that of skim milk, resulting in improved health.
What is
required for sub-Saharan Africa, in addition to better seeds of wheat, rice and
maize, I believe, is focused research to enhance yields and quality of some of
the “orphan crops” that are important in the diets of Africans: cassava, sweet
potatoes, sorghum and millet, lentils and cowpeas, among others.
More
generally, for planet Earth’s growing population, both conventional and
biotechnology research on food crops and livestock, both private- and
public-sector funded, is absolutely essential to provide ever-more-powerful
seeds as well as a continuing stream of improved technology to energize the
catalytic power of seeds.

1.02 A national workshop on “Sustaining plant breeding as a vital national capacity for the
future of U.S. agriculture”
Save the date to save plant
breeding! See the announcement below, and spread the word. – AMT
8-9 February 2007, Raleigh, NC
Co-hosted by the Departments of
Crop Science and Horticultural Science North Carolina State
University
The national investment in plant breeding is declining. Is
this cause for concern? What are constructive responses? The Plant
Breeding Coordinating Committee is being organized as a permanent forum for
leadership regarding this and other issues, problems, and opportunities of
long-term strategic importance to the public and private plant breeding
profession and to the U.S. national plant breeding effort as a
whole.
Participants in this national workshop will:
1) organize the
Plant Breeding Coordinating Committee, including first election of officers;
and,
2) provide the Plant Breeding Coordinating Committee with guidance for
its initial work.
Keynote speakers will look at plant breeding in the context
of our national goals for agriculture:
-Excellence in science and
technology.
-A competitive agricultural system in the global economy
-A
safe and secure food and fiber system
-A healthy, well-nourished
population
-Harmony between agriculture and the environment
-Economic
opportunity for rural areas; and quality of life for all
Americans.
Working groups will analyze plant breeding’s role and key
partners for each goal, and formulate action plans for positive effect on future
plant breeding capacity to support these national goals.
To
be on the list for workshop announcement updates, email to:
athro@csrees.usda.gov.
Target participants include:
-U.S. public and
private sector plant breeders, all crops
-Students of plant
breeding

1.03 Global Initiative for plant
breeding capacity building
FAO has been assessing national plant
breeding and biotechnology capacity around the world. The results of this
work are helping to identify opportunities and gaps to strengthen national
capacity to use plant genetic resources for food and agriculture (PGRFA).
This coming June (12-14), in Madrid, Spain, during the first meeting of the
Governing Body of the International Treaty on Plant Genetic Resources for Food
and Agriculture (IT), FAO and partners will launch an initiative called “The
Global Initiative for Plant Breeding Capacity Building” (GIPB). It is
proposed as a partnership of public and private sector parties from both North
and South, working in concert through a ‘lightweight coordination
mechanism”. GIPB’s goal is to enhance the capacity of developing countries
to improve their agriculture through sustainable utilization of PGRFA using
better breeding and seed delivery systems. GIPB is proposed to operate
with an independent work programme under the policy guidance of the Governing
Body of the IT. The GIPB focuses on enhancing the use of plant genetic
resources; therefore it will complement the existing Global Crop Diversity
Trust. The Trust, also reporting to the Treaty, focuses on ensuring
conservation of major collections of PGRFA.

1.04 Summary reports on strategies to strengthen national plant
breeding capacity
FAO, in partnership with CIMMYT and ICARDA, carried
out three national workshops in Central Asia (Uzbekistan, Tajikistan and
Kazakhstan) with the objective to design strategies to strengthen national plant
breeding and associated biotechnology capacity. Following the national
events a regional workshop was held in Almaty, Kazakhstan. The
results of these workshops are indicating that the main issues to strengthen the
region’s capacity are:
-investments in plant breeding and applications of
biotechnology tools;
-capacity building through post-graduation programmes
and short specific training, including hands-on activities, and genetic
resources information;
-documentation, characterization and exchange, main
for crops that fall outside the CGIAR mandate crops.

1.05 Africa maize stress project
reviewed
The Africa Maize Stress Project (AMS) is developing maize
varieties tolerant to drought, low soil fertility, Striga weed, and endemic
pests and diseases. In a recently completed review by a three-member panel from
the German Corporation for Technical Cooperation (GTZ) the AMS was termed a "flagship project." According to team leader Dr. Manfed van Eckert, the
reviewers recognized qualities that could serve as a model for similar
multi-faceted projects in Africa. Among these were the "excellent working
relations with national partners, and the Eastern and Central African Maize and
Wheat (ECAMAW) Research Network."
AMS is supported by Germany's Federal
Ministry for Economic Cooperation and Development (BMZ), the International Fund
for Agricultural Development (IFAD), the Swedish International Development
Cooperation Agency (SIDA), and the Rockefeller Foundation, and works with
national agricultural research systems (NARS), NGOs, and seed companies in 10
eastern and central African countries. Other partners in the project include the
International Maize and Wheat Improvement Institute (CIMMYT), the International
Institute of Tropical Agriculture (IITA), and national research
programs.
The GTZ team recommended that in its next phase, AMS advance
current activities "investigate sustainable financing options for maize breeding
programs in the region." For more information contact Alpha Diallo at a.diallo@cgiar.org.

1.06 WARDA scientist wins rice prize
Dr. Moussa Sié, Lowland Rice
Breeder from the Africa Rice Center (WARDA) , has been chosen as one of the two
laureates of the 2006 Fukui International Koshihikari Rice Prize of Japan in
recognition of his significant contributions to rice production in sub-Saharan
Africa. Dr Sié shares the prize with Dr. Akihiko Ando from Brazil, who has
contributed to rice breeding by using radiation-induced mutations.
Dr.
Sié has over 20 years experience in the selection and improvement of rice
varieties, with particular emphasis on rain-fed systems; and is credited with
the development of several high-yielding and multiple stress-resistant rice
varieties. He was also instrumental in extending WARDA's upland New Rice for
Africa (NERICA) rice breakthrough to lowlands - one of the most complex rice
ecologies in the world.
Key to Dr Sié's success was the unique R&D
partnership model forged between WARDA and the national programs of West African
countries through the ROCARIZ rice network, which facilitated the
shuttle-breeding approach to accelerate the selection process and achieve wide
adaptability of the Lowland NERICAs.

1.07 Ethiopian
bills for plant breeder’s rights and biodiversity
The House of
Peoples' Representatives of Ethiopia recently endorsed two bills: the Plant
Breeders' Right and the Genetic Resources and Community Knowledge and Rights.
The Plant Breeders' Right bill aims to enable the private sector to release new
plant varieties suitable for the local ecosystems and environmental conditions
of the country, and will encourage private investment and facilitate the
utilization of crop varieties developed abroad. The bill was presented by the
Rural Development and the Natural Resources and Environmental Protection
Standing committees of the House.
The Bill Providing for Genetic
Resources and Community Knowledge and Rights is set to provide protection of
Ethiopia's genetic resources, as well to facilitate the expansion of investment
and the equitable share of the benefits of utilizing local genetic
resources.
The bill was presented by the Rural Development, Legal,
Information and Cultural Affairs Standing Committees. Member of the Committee
indicated that community knowledge and recognition given for community resources
would have immense contribution for the protection and preservation the genetic
resources of the country.

1.08 CIMMYT brings the best in
wheat
Scientists talk wheat at the place where the green
revolution began
Prominent players in global wheat
researchhailing from Azerbaijan to Zimbabwe and about 20 countries in
betweenarrived at Ciudad Obregón, Mexico in late March to chart a course
for wheat research in the developing world for the coming decade.
Approximately 130 participants attended the weeklong “International
Symposium on Wheat Yield Potential: Challenges to International Wheat
Breeding,” sponsored by CIMMYT and the Australian Centre for International Agricultural
Research (ACIAR).
“This symposium has been a tremendous opportunity
for sharing ideas and learning right across the world’s wheat research
fraternity,” concludes Tony Fischer, ACIAR Program Advisor for South Asia. “The
representation from both the developing and the developed world is very good and
we once again see that in the developing world innovation system CIMMYT
continues to play a huge leadership role.”
“The original purpose,” says
symposium organizer and CIMMYT wheat physiologist Matthew Reynolds, “was to disseminate new
technologies that would improve the efficiency of wheat breeding in lesser
developed countries. We achieved that and much more. We delivered the results of
our ACIAR project on early generation selection and improved understanding of
the fundamental constraints to yield potential, but then went on to a wide range
of very topical subjects covered by top experts in the field.”
The
meeting opened with a keynote address by Dr. Norman Borlaug entitled “Personal
Reflections of 62 Years of Fighting Hunger.” Following the warmly received
address, the symposium got down to business with a series of 40 technical
presentations. A poster session addressing wheat breeding and production (and
related constraints) in 17 countries ensured that NARS perspectives were well
represented. The concluding day of the meeting was devoted to breakout and
reporting sessions to define wheat research initiatives and explore the roles of
CIMMYT, advanced research institutes, and NARS in putting the plans into action.
CIMMYT held a similar meeting nearly ten years ago to the day, which
focused primarily on increasing yield potential, breeding for drought, and the
use of molecular tools. While these items, particularly water use efficiency,
remain high on CIMMYT’s agenda, the symposium participants observed that the
world wheat situation and agriculture generally is rapidly changing, and
consequently, new priorities have emerged. NARS representatives flagged high
priority issues such as conservation agriculture, the need for higher quality
wheat bred for specific food and industrial uses, and breeding with climate
change in mind, notably heat stress.
“There were a number of exciting
new ideas that emerged from this symposium, says Hans Braun, Director of the
CIMMYT Wheat Program, “all of which depend on ever closer links between
scientists in the international wheat community. In our final sessions we
crystallized these into research thrusts that we would like to incorporate into
our existing program.”
Braun said three major areas cited for more
intensive research emerged from the interactions:
-Integration of
physiological trait-based approaches into conventional breeding schemes to
advance progress on complex traits associated with yield and stress adaptation.
This entails dissecting yield into its physiological components and using
conceptual models to increase the likelihood of combining complementary genes to
capture the desired trait. CIMMYT terms this use of physiological markers
physiological breeding or “smart crossing.”
-More
systematic characterization of target environments than in the past. Combining
comprehensive environment data with CIMMYT’s exceptional and extensive
phenotypic data of genotypes will greatly expand our knowledge about genotype x
environment interaction. This will be further catalyzed by new tools and
methodologies in the areas of geographic information systems, advanced
statistics, modeling, and bioinformatics.
-Conservation agriculture (CA)
was strongly endorsed as a strategy for buffering the adverse effects of
environment on crop yields, especially in the face of climate change and reduced
water resources. This is in addition to CA’s role in stabilizing the natural
resource base and reducing long-term dependence on agro-chemical inputs.

1.10 Breeding wheat varieties for the
future
London, United Kingdom
A low-nitrogen, high-energy wheat
for biofuels, varieties with improved resistance to septoria and fusarium ear
blight, and research that has already delivered results on fighting orange wheat
blossom midge, were amongst the topics reviewed at a recent HGCA plant breeders seminar.
The event was
organised by HGCA to review and disseminate results from a number of the
on-going wheat breeding research projects which they partially fund, many
through the Defra-sponsored Sustainable Arable LINK programme
The 'GREEN
grain' project is looking at wheat as an energy source for feed, potable alcohol
or bioethanol where high-energy, low-protein grain is advantageous.
"The
project will test the hypothesis that wheat genotypes with low nitrogen storage
in stems and grains will show halved nitrogen fertiliser requirements, and will
produce grain of higher value for the feed and bioethanol industries," said
Professor Graham Jellis, HGCA's director of research.
Projects are
investigating resistance in varieties to a number of different diseases
including soil-borne cereal mosaic virus, fusarium ear blight and mycotoxins,
and septoria.
"Although much of this work is geared towards securing the
long-term future of farming, it can provide answers for today," said Professor
Jellis. "Results from the project looking at wheat varieties resistant to orange
wheat blossom midge have already been passed to growers through the HGCA
Recommended List."
"An HGCA review looking at the areas of research
favoured by growers showed strong endorsement for plant breeding, both for what
it can offer in helping with the issues of today, and in addressing the
challenges facing farming in the coming years," said Professor
Jellis.

1.11 University of California, Berkeley joins Africa
Biofortified Sorghum (ABS) project
Berkeley,
California
Researchers at the University of
California, Berkeley, are joining an ambitious project to improve nutrition
for 300 million people in Africa who rely on sorghum as a principal source of
food.
The Africa
Biofortified Sorghum (ABS) project is funded by a $17.6 million grant from
the Grand Challenges in Global Health initiative to Africa Harvest Biotechnology
Foundation International, a non-profit organization dedicated to fighting hunger
and poverty in Africa.
"Our goal is to develop sorghum that will provide
increased calories and needed protein in the diet of African consumers," said
Bob B. Buchanan, UC Berkeley professor of plant and microbial biology and one of
the lead scientists on the project. "We are extremely happy to offer our
expertise and materials for this important project for the public good."
The announcement of UC Berkeley's participation was made from Nairobi,
Kenya, today (Monday, April 10) by project leader Florence Wambugu. "All the
project consortium members are delighted that researchers from UC Berkeley will
be joining the team," said Wambugu, who is a plant pathologist and CEO of Africa
Harvest. "Their contribution will provide a second avenue to ensure success in
achieving the important goal of increasing digestibility of sorghum."
The Grand Challenges in Global Health initiative is supporting
nutritional improvement of four staple crops - sorghum, cassava, bananas and
rice - as one of its 14 "grand challenges" projects that focus on using science
and technology to dramatically improve health in the world's poorest countries.
The initiative is funded by the Bill & Melinda Gates Foundation, the
Wellcome Trust, and the Canadian Institutes of Health Research.
In June
2005, the initiative awarded $16.94 million to Africa Harvest to head a
consortium of public and private research institutes for the ABS project. The
Gates Foundation has just supplemented this amount with $627,932 to fund the
work of Buchanan and co-researcher Peggy G. Lemaux, UC Berkeley Cooperative
Extension specialist in plant and microbial biology.
The two will
address the digestibility portion of the sorghum project, basing their work on
studies they have been conducting for over a decade in their laboratories. Their
work will complement approaches being pursued by other ABS consortium members.
Sorghum is the sixth-most planted crop in the world and has long been a
staple in many regions of Africa and Asia. It is valued for its resiliency,
growing well in dry, hot climates and on poor soils, but it lacks high levels of
vitamins and minerals and is difficult to digest, especially when cooked.
Buchanan and Lemaux expect their sorghum seed to have enhanced protein
and starch digestibility so people can obtain improved nutritional value from
sorghum consumption. The researchers will achieve this improvement by increasing
the levels of two proteins naturally present in the starchy part of the grain.
These two proteins are part of the NADP-thioredoxin (Trx) system, an
oxidation-reduction system that occurs naturally in all living organisms.
"By breaking disulfide (S-S) bonds of certain storage proteins in the
sorghum grain, the introduced Trx proteins are expected to make previously
indigestible protein and starch available for digestion," said Buchanan, who has
worked with these proteins for over three decades. The researchers will also
introduce another protein into the grain that will increase levels of three
protein building blocks-- lysine, threonine and tryptophan -- that are currently
present at low levels in sorghum.
The improved sorghum varieties
developed by UC Berkeley scientists will be bred with varieties now under
development by the ABS project for improved vitamin and mineral content, and
then incorporated by classical breeding into varieties of importance to Africa.
Negotiations for UC Berkeley to join the consortium of companies,
agencies and universities working on the sorghum project were led by Peter
Schuerman, associate director in the Industry Alliances Office, which is part of
the campus's Office of Intellectual Property and Industry Research Alliances
(IPIRA).
"Berkeley is increasing our impact on society through strategic
relationships that maximize social benefit," Schuerman said. "This agreement is
part of a continuing program at Berkeley - the socially responsible licensing
initiative - to use the university's knowledge, expertise and resources to
address critical unaddressed social problems."
Now in its third year,
the initiative has thus far yielded more than 10 separate agreements that
address the needs of the developing world. "I think it's a moral imperative for
land-grant institutions that have basic research that happens to have societal
application to expeditiously translate it into goods and services for the
public," said Carol Mimura, IPIRA's assistant vice chancellor. "Public-private
partnerships of this sort are important because they bring resources to problems
where traditional market drivers do not exist."

1.12 Cataloguing wheat DNA will lead to
quicker breeding
A group of public wheat breeders and scientists from
the Southeast have been awarded $5 million from the U.S. Department of
Agriculture. The funds are earmarked to make using DNA technology a routine part
of wheat breeding nationwide.
A group of public wheat breeders and
scientists from the Southeast have been awarded $5 million from the U.S.
Department of Agriculture. The funds are earmarked to make using DNA technology
a routine part of wheat breeding nationwide.
The project involves wheat
scientists from Georgia, Kentucky, Maryland, North Carolina and
Virginia.
Mapping traits
"This grant gives us the opportunity
to map a lot of very important wheat traits that aren't available at the present
time," said Jerry Johnson, head of the small grains breeding program in the
University of Georgia College of Agricultural and Environmental Sciences. "The
DNA markers will allow us to develop wheat cultivars much more efficiently and
quickly."
Using traditional breeding methods, it can be up to 10 years
from the time a researcher begins crossbreeding plants before a farmer can plant
the new variety.
"With a lot of traits, we have to wait until we've grown
out several plant generations to truly verify that we have the trait in the new
cross," Johnson said.
"Having DNA markers will allow us to verify these
traits earlier and will greatly improve breeding efficiency," he said. "It will
also allow us to combine pest resistance more effectively to improve new
varieties."
Built-in resistance
For the project, the research
team will focus on identifying wheat genes that resist diseases like powdery
mildew, leaf rust, stripe rust and fusarium head blight. All of these diseases
affect wheat in the Southeast. Powdery mildew alone causes annual crop losses of
10 percent to 30 percent in this region.
As a result of the grant
project, U.S. wheat breeders will have access to more than 80,000 DNA analyses
per year. Breeders can then use these markers to precisely select genes that
improve quality or provide resistance to pathogens and pests.
USDA
genotyping labs will provide the molecular analysis required to deploy the
targeted genes into breeding lines. The genetic information will then be stored
in national databases. Seed stocks will be deposited in the USDA Small Grain
Collection.
This will provide long-term, public access to the genetic
information for wheat breeders and researchers worldwide, Johnson
said.
For the sake of pizza and cookies
The wheat research team
will also work to identify genes known to produce wheat with superior milling
and baking qualities.
"The continuous improvement of U.S. varieties is
essential to produce better bread, cookies and pasta products," Johnson said.
"New releases also help U.S.-grown wheat compete internationally."
UGA
wheat breeders have released more than 35 new varieties geared to help growers
fight pests and produce high-quality, high-yield wheat. Johnson's breeding
program at UGA released two new varieties last year and will release two more
this year.
Besides the DNA technology, the project also includes an
outreach effort. Information about the new DNA marker technology will be shared
with growers and the public. An educational program will be geared to attract
students to agriculture.
"We will train the students in molecular and
traditional breeding technologies," Johnson said. "Hopefully, their interest
will be sparked and they'll become our nation's future wheat
breeders."

1.13 Aiming at a never-ending supply of rice
College,
Laguna, The Philippines
Did it ever occur to you where rice came
from?
Myths tell us that as early as 4000 years ago, the Chinese cultivated
rice and later it was introduced to India, where the natives saw this plant and
started tinkering this crop for food.
Much later, this rice trekked all
the way to America through a certain ship captain who docked in Charleston South
Carolina harbor. The man who received it planted it and in 1726, the place
harboring it started to export rice. Today, in various parts of the globe, rice
has flourished and has become a basic staple food to many.
In the
Philippines and in most of Asian countries, rice is part of the day's main
meals, 365 days a year.
Aiming at a never-ending supply of rice is not
just a simplistic "Let's plant rice today and harvest in 120 days." There's more
to it than meets the eye.
Dr. Robert Zeigler1, Director-General of Los
Baños, Laguna-based International Rice Research Institute (IRRI), says that 10
to 20 years from now, IRRI will be facing head-on four major challenges. These
are poverty alleviation, sustaining and maintaining the environment, human
health and nutrition, and scientific capacity to address these
challenges.
Alleviating poverty and maintaining human health
Rice is
grown by farmers mostly from rainfed areas which are prone to erratic rainfall,
flooding, and ironically, drought. And even if rice would grow and produce
grains, the yield would barely enable the farmers to survive until the next
cropping.
However, with the present "revolution in genomics" Zeigler says
that much can be done to make rainfed areas more productive. To reduce poverty,
Zeigler says that other cash crops need to b e explored. "…we look on the
revolution in genomics being a tool to allow us to provide flexibility to
farmers and get them out of that poverty trap."
Moreover, large areas in
Asia have been reported to be malnourished. By using biotechnology, scientists
can enrich the nutritional value of the crop and address
malnutrition.
Sustaining environment
Rice farming needs a lot of
water, nutrients, protection from pests, etc. Science's part in lightening the
load of rice farming on the environment is to find measures to reduce water,
nutrient, chemicals, and green gases emissions so that these will not be too
damaging on the environment.
Water-saving technologies, nutrient uptake,
and environmentally-friendly pest management practices can be explored. Zeigler
points out that "The real challenge than is to understand how to get farmers to
go to their fields and monitor their crops; there are many alternatives to their
time and the opportunity costs of some of the intensive management systems are
going to be a challenge to us."
Scientific capacity
Aiming at a
never-ending supply of rice for the peoples of Asia is an intricate goal.
Zeigler opines that policy issues and concerns "are completely interwoven" with
poverty, human nutrition/health, environment, and scientific factors. Thus,
"there's a tremendous opportunity and it is absolutely essential for the
technical scientist to work very closely with the economists, social scientists,
and policy specialists to make sure that we get our technical solutions right so
they fit within the policy context and therefore would stand a much better
probability of being adopted."

the SEARCA International Conference on "Agricultural and Rural Development in

1.14 MSU researchers shake out basis for rice
domestication
Michigan State University scientists have identified
the genetic mutation that reduces grain shattering during rice domestication
research that will improve production of the crop that feeds more than half of
the world's population.
In an article on the cover of the March 31
edition of Science Magazine, MSU scientists, led by Tao Sang, associate
professor of plant biology, identify for the first time the genetic mutation for
the reduction of shattering, a key step in the domestication of all cereal crops
including corn and wheat.
The researchers were able to pinpoint and
confirm that a single base pair mutation in DNA causing an amino acid change in
a protein led to non-shattering rice varieties. This slight change in DNA
prevented mature rice grains from easily falling from stalks to allow a more
effective field harvest. In essence, humans several thousand years ago
unknowingly practiced de facto gene selection by planting varieties with this
trait.
Shattering in cereal crops refers to grains easily falling off of
plants. The shattering trait of the wild forerunners of rice and cereals
prevents effective field harvest and is undesirable for cultivation.
"What we can learn from historical plant domestication will benefit our
ongoing and future effort to domesticate energy crops that will be equally
important to the long-term sustainability of our society," Sang said. "It is
remarkable how the earliest farmers could have selected a single mutation in DNA
to develop a major food crop of the world."
The researchers first
determined which chromosomal regions contained the mutations selected for rice
domestication. Chromosome 4 was pegged as being responsible primarily for the
reduction of shattering.
"Several hundred hours were spent in the
greenhouses where we had to shake the plants and record the various degrees of
shattering," Sang said. "Even with all the advances in technology, a careful
firsthand observation proves to be essential for biological research."
The researchers then developed a new method for rapid and cost-effective
DNA isolation to clone a gene from the chromosomal region. Changbao Li, research
associate in plant biology, invented a process that increased the speed of DNA
isolation and allowed researchers to efficiently complete the screening of
12,000 seedlings.
"This technical innovation will greatly speed up
genetic research for plants since it saved us time and money, yet delivered
accurate results," Sang said.
"By tracing the breeding of rice and
identifying the genetic mutations, the researchers have opened new doors to the
science community that benefit the world through a more effective use of the
land and water used to grow rice," said Rich Triemer, chairperson of the
Department of Plant Biology.
"These findings will improve yields to a
crop that is the staple food for more than half of the world's population. Our
scientists are continuing the legacy started by William Beal more than one
hundred years ago of using plant research to benefit the world," he said.
The article, "Rice Domestication by Reducing Shattering," was published
today in Science Express an electronic publication designed to get important
papers quickly in front of the scientific community prior to being published in
Science. Science is the world's leading journal of original scientific research,
global news, and commentary and is published by the American Association for the
Advancement of Science.

1.15 New initiative may lead to better
peanuts
Washington, DC
The researchers, with ARS’ Wheat, Peanut
and Other Field Crops Research Unit, are joining the Oklahoma Peanut Commission
and state research and extension professionals in a new, wide-ranging program to
produce disease-resistant plants with tasty, fresh and healthful peanuts for
consumers.
Plant pathologist Hassan Melouk and biologist Kelly Chenault
lead the ARS team. According to their research leader, Dave Porter, the new
program fortifies and expands the ARS unit's efforts to enhance, through
breeding, peanut plants' genetic diversity, and to develop superior peanut
products.
The new initiative, which was started in response to recent
declines in peanut production in southern Plains states, can help growers meet
an increasing demand for peanuts through economical, sustainable and
environmentally compatible management strategies, as well as spur improved crop
production that allows for less pesticide use and greater product value, quality
and safety, according to Porter.
This united effort will benefit from the
continuation of Melouk's work on combining traits of peanut plants that resist
diseases with those that boost oleic acid content. Studies have shown that oleic
acid--which staves off deterioration and gives peanut products longer shelf
life--may promote a lower risk of coronary heart disease.
Melouk is
working with peanut lines from Bolivia and Ecuador that resist Sclerotinia
blight and may be a boon to breeding in the United States. His previous work
with Oklahoma State and Texas A&M universities generated cultivars that
resist the blight. Some of the cultivars also produce oil with high oleic acid
content.
The new initiative will also benefit from Chenault’s
breakthroughs on the genetic front with disease-resistant peanut plants. Her
goal is to someday integrate disease-resistance genes into susceptible peanut
varieties.

Plants give pests sock in the gut
A novel enzyme
in corn helps the plants defend themselves from voracious caterpillars by
disrupting the insects' ability to digest food, and ultimately killing them,
according to researchers. The enzyme could be used in tandem with other
biological pesticides such as the Bt toxin to prevent the pests from developing
resistance and making the toxin more effective.
"The enzyme is found in
insect-resistant strains of corn, and it breaks down proteins and peptides in
the insects' gut. It is a unique active defense against herbivory," says Dawn
Luthe, professor of plant stress biology at Penn State.
Luthe and
researchers at Mississippi State University have since developed several lines
of corn resistant to multiple pests, using conventional plant breeding and
insect-resistant strains of corn from Antigua.
Researchers have found
that when caterpillars fed on the insect-resistant plants, one enzyme -- Mir1-CP
or maize insect resistance cysteine protease, in particular --accumulated at the
feeding site within an hour of the caterpillar's feeding and continued to
accumulate at the site for several days.
"Upon isolation and
purification of the enzyme, we found that Mir1-CP binds to chitin, a major
component of insects and fungi," says Luthe. "Physiological tests show that
caterpillars have impaired nutrient utilization when they eat the enzyme. They
just can't convert what they eat into body mass."
Luthe presented the
findings at the annual meeting of the American Chemical Society today (March 30)
in Atlanta.
With the help of antibodies specific to the enzyme, the
researchers were able to determine that Mir1-CP is made in the vascular bundles,
or strands of conducting vessels in the stem and leaves of a plant. Luthe thinks
that when an insect starts feeding, the enzyme is probably transported to
vascular tissue that conducts sugars and other metabolic products upward from
the leaves, as well as to the soft tissue found in leaves and stem.
Though it is still unclear whether the transport of Mir1-CP is a
specific response to the insect feeding, studies show that maize tissue that
naturally expresses Mir1-CP causes a 50 percent inhibition in caterpillar
growth. Transgenic black Mexican sweet corn cells that express Mir1-CP inhibit
caterpillar growth by 70 percent, Luthe says.
Mir1-CP is harmful to
caterpillars mainly because of its damaging effect on their peritrophic matrix.
This is a membrane that lines the gut of most insects and aids digestion. It
also protects the insects from being invaded by microorganisms and parasites
through the food they eat.
At the heart of the matrix is a protein
called the insect intestinal mucin, or IIM. It is very similar to the mucus
layer in animals and is vital for nutrient utilization because it helps the flow
of nutrients into the food gut.
The researchers tested the permeability
of the matrix using blue dextran, a fermented sugar solution commonly used as a
molecular size marker. Results showed that Mir1-CP created holes in the matrix.
To replicate the test in vivo, the researchers fed caterpillars with
plants susceptible to the insects and those resistant to them. Results indicate
that after seven days, the level of both IIM and IIM messenger RNA in insects
that were feeding on the resistant plants had fallen significantly.
"If
the IIM is being degraded by the enzyme, pieces of it should not appear in the
fecal pellets of the insect," notes the Penn State researcher.
When used
in conjunction with the Bt-toxin, a low dose of Mir1-CP was able to achieve a
very high mortality rate in the insects, as well as an extremely low growth
rate.
"In the long run, the enzyme degrades the insect's peritrophic
matrix and retards the caterpillar's ability to generate a new one," says Luthe.
The research has potential global implications in generating a cheap and
highly effective way of controlling crop pests.
Other authors of the
paper include Tibor Pechan, Srinidi Mohan, Renuka Shivaji, Lorena Lopez, Alberto
Camas, Erin Bassford, Seval Ozkan, Peter Ma, all at Mississippi State
University; and W. Paul Williams, U.S.D.A.

1.17 Botanical gardens not just 'pretty places'
Botanical
gardens play an often unrecognised role in international development from
supplying medicinal plants to HIV/AIDS patients to improving urban food security
according to a report published today (20 April).
The report by
Botanic Gardens Conservation International argues that botanical gardens
are uniquely placed to use plant diversity to contribute to human
wellbeing.
"We feel it is both a practical and ethical imperative that
botanic gardens are encouraged and enabled to link plant conservation with
improvements to human wellbeing," says Suzanne Sharrock, the organisation's
public awareness director.
"We hope the report will help to build support
for them especially in developing countries."
The report stresses
that many botanical gardens have a strong research emphasis, and are involved in
developing plants for use in agriculture and healthcare.
The Kisantu
Botanic Garden in the Democratic Republic of Congo, for example, has conducted
research to extend the shelf life of mangosteen fruit. Ghana's Aburi Botanical
Garden has been improving access to herbal medicines by helping local
communities to set up medicinal gardens.
While it is possible that
displaying plant diversity in such centres could slightly increase the risk of
samples being taken by unscrupulous researchers, Sharrock believes that research
benefits provided by the gardens greatly outweigh such risks.
"Being able
to produce plant material in a sustainable way is likely to empower communities
and reduce such biopiracy, rather than promoting it," she told
SciDev.Net.
The report also notes botanical gardens' role in plant
conservation. Many globally threatened species are represented in their living
collections and seed banks.

the largest professional body representing 800 botanical gardens in 120
countries.

1.18 Global actors, markets and rules
driving the diffusion of GM crops in developing countries
The
adoption of the technology of genetic modification (GM) in developing countries
is shaped by a number of players, which include multinational corporations,
scientists, farmers, consumers, and anti-globalization and environmental NGOs;
and is also influenced by global and national markets and by international and
national rules on intellectual property rights and biosafety. Sakiko Fukuda-Parr, of Harvard
University, explores some of the policy issues for developing countries related
to the introduction of GM crops, and argues that developing economies should
develop policy approaches that are specific to their own unique set of
circumstances. Her essay, entitled “Introduction: Global actors, markets and
rules driving the diffusion of genetically modified (GM) crops in developing
countries”, is published in the second issue of the International
Journal of Technology and Globalisation 2006 - Vol. 2, No.1/2 pp. 1 -
11.
While crop breeding and improvement have traditionally been
public sector initiatives, several factors have contributed to provide powerful
market incentives to the private sector of developed countries to invest in
agriculture in the last two decades. These factors include: scientific advances
in molecular biology; changes in the legislation, in particular with regards to
property right protection; and the availability of large US seed markets for
maize, soy, canola, and cotton. As a result, the first biotech crops that were
commercialized are mainly crops suitable for temperate zones, and industrialized
countries currently account for 65% of the total area planted with biotech
crops. However, Argentina is the second country in terms of biotech crop
production, and diffusion is rapid in Brazil, China, and India, countries which
are investing heavily on crops and traits that fit their local priorities and
requirements.
Efforts to develop crops tailored to suit local needs, and
aimed at the local markets of developing nations for the benefit of
resource-poor farmers, “cannot depend entirely on national public sector efforts
alone” argues Fukuda-Parr. The author adds that “public-private partnership,
building regulatory and IPR enforcement mechanisms, and having the right kind of
IPR regimes globally are all critical.”
ABSTRACT
The theme of this
special issue – genetically modified (GM) crops – goes to the heart of the
process of globalisation, technology and development. This introductory essay
explains how this new technology is being driven by the actors (multinational
corporations), markets (large global markets) and rules (intellectual property)
of globalisation. But it is also shaped by the other national and global actors
(farmers, research scientists, anti-globalisation and environmental NGOs),
markets (national priorities) and rules (national biosafety). The papers in this
issue address some policy questions for developing countries: markets that are
too small for corporate sector, or to be kept GM free, or dominated by monopoly
products; the rules of intellectual property rights and the enforcement of
biosafety regulation. Developing countries need to develop policy approaches
that are specific to its own unique set of circumstances.

Genetic markers point toward low linolenic acid
soybeans
Agricultural Research Service (ARS) scientists in the Plant
Genetics Research Unit at Columbia, Mo., are improving soybean oil’s
longevity--and marketability--by lowering its linolenic acid
content.
Most soybeans contain high levels of linolenic acid, which has
double chemical bonds that break down in the presence of air, heat and light,
according to molecular biologist Kristin Bilyeu at Columbia. This is a
troublesome trait for producers and consumers who want durable, shelf-stable
food.
Soy oil is often partially hydrogenated to reduce linolenic acid.
Hydrogenation increases products’ shelf life and stability, but produces trans
fats (also called trans fatty acids), which several studies have linked to high
cholesterol and heart disease.
With growing public awareness and new
laws requiring food labels to list trans fats, the food oil industry would
welcome an alternative to hydrogenated oils. Could low-linolenic soybeans
provide the solution?
With colleagues from ARS and Iowa State University
(ISU), Bilyeu has developed molecular markers that identify specific mutations
in three genes which can be used in plant breeding programs to lower soy oil’s
linolenic acid content. Oil from the low-linolenic soybeans does not require
hydrogenation.
Walter Fehr of ISU and James Wilcox, formerly with ARS,
identified the low-linolenic soybean lines in mutant plants that Bilyeu used to
identify the mutant genes and develop the molecular markers.
Usually,
soybean breeders depend on random segregation of the three genes for
low-linolenic acid. Using these new markers will improve the identification of
soybean genotypes for low linolenic acid content. Eventually, Bilyeu hopes the
breeding process will result in stable, nutritious beans for the food oil
industry.
The QualiSoy Initiative, under the auspices of the United
Soybean Board, is helping to bring seed companies, processors, and food
manufacturers together to expand the market for low-linolenic soybean oil. This
oil would create a competitive advantage for growers and allow food
manufacturers and vendors to market long-lasting products without compromising
their nutritional value.

1.20 Bacterial gene could help crops beat the heat of global
warming, say University of Florida researchers
Gainesville,
Florida
Though E. coli bacteria are notorious for making people sick, a University of Florida study shows that a gene
found in the microbes can keep plants healthy by improving their resistance to
heat stress – a discovery that may help researchers develop food crops that
withstand harsh climates and global warming.
Tobacco plants carrying the
gene thrived after spending a week in nonstop 95-degree heat, said Bala
Rathinasabapathi, an associate professor of horticultural sciences with UF’s
Institute of Food and Agricultural Sciences. The gene poses no threat to
human health.
Researchers believe the plants were unusually resilient
because they contained up to four times the normal amounts of vitamin B-5 and
one of its components, the amino acid beta-alanine, he said.
The UF study
appears in the March issue of the journal Plant Molecular Biology.
“We’re already researching the gene’s effect on tomatoes and lettuce,
which are economically important to Florida and vulnerable to heat,” said
Rathinasabapathi, who co-authored the study with graduate student Walid Fouad.
“Large-scale application is several years away but we believe this technology
will be practical and affordable. It’s certainly needed.”
Up to 20
percent of the world’s food crop is lost to heat stress each year, he said. That
figure is likely to increase if predictions of future global warming prove
correct.
According to the U.S. Environmental Protection Agency, many
scientists believe the Earth’s average surface temperatures will increase by up
to 10 degrees in the next century.
Besides fighting crop loss, the gene
could enable farmers in tropical and subtropical areas to grow a wider variety
of foods, Rathinasabapathi said.
The connection between the gene and
heat tolerance was discovered by accident, as researchers tried to learn how
plants make beta-alanine. The process is well understood in bacteria, so the
researchers decided to take a gene that helps regulate beta-alanine production
in E. coli and observe its effects in plants.
They transferred the gene
to tobacco, a species popular in genetic research. During an experiment on heat
stress, Fouad was surprised to find plants carrying the gene were taller than
their ordinary counterparts.
“We hypothesized that the plants grew taller
and larger under higher than optimal temperatures because something associated
with the gene protected them from heat,” Rathinasabapathi said. “One possibility
was that the large amounts of beta-alanine and vitamin B-5 they were producing
played a role.”
In the current study, researchers found tobacco plants
modified with the gene contained four times as much beta-alanine and vitamin B-5
as ordinary tobacco plants. And modified plants exposed to 95-degree heat for
one week weighed almost twice as much as ordinary plants grown under the same
conditions.
But when the modified plants were kept at temperatures
typical for tobacco farming – about 75 degrees – they grew at the same rate as
their ordinary counterparts.
“The practical applications for this gene
may be limited to situations where crops will be exposed to temperatures of 90
degrees or more,” Rathinasabapathi said. “We’re conducting follow-up studies to
learn more about how the gene works, so we can maximize its
benefits.”
The UF study marks one of the few times a plant’s metabolic
system has been successfully changed with genetic engineering, said Ulrich
Genschel, a junior group leader at the genetics department of the Weihenstephan
Center of Life Sciences in Freising, Germany, part of the Technical University
of Munich.
The findings suggest beta-alanine helps plants tolerate heat
but it may play a supporting role, he said. Plants use beta-alanine to make
other substances – such as vitamin B-5 – and one of them could provide the
actual protection.
“In any case, this work emphasizes the importance of
the biochemical pathway involved in vitamin B-5 production,” said Genschel, who
studies vitamin B-5 production in plants and microbes. “It will be interesting
to see what else the authors discover about the role of beta-alanine in
plants.”

1.21 Kenya advances on GM cotton
Michael Ouma
The Kenya Agricultural Research Institute (KARI) is
currently conducting confined field trials of insect resistant genetically
modified (GM) cotton with the Bt gene Cry1Ac. The four-month-long trials are
being used to measure economic impacts and the Bt gene's effectiveness against
bollworm pests. The article says that several biosafety measures have put in
place at the test site; the test field is separated from other cotton fields by
a 500 meter separation distance, and all of the material from the test will be
incinerated on-site. Members of Kenya's National Biosafety Committee and the
Kenya Plant Health Inspectorate Service (KEPHIS) will inspect the site
periodically. The article reports that cotton production has fallen dramatically
in Kenya over the past years, from 70,000 bales in 1986 to just 20,000 in 2000,
with insect pests "the main factor" behind the drop-off. [According to a related
article (Crop Biotech Update; April 21), Kenyan members of parliament (MPs) from
the House committees on "Agriculture, Lands, and Natural Resources" and
"Education, Research, Science, and Technology" recently visited the GM test
site. The MPs "expressed their commitment to key biotechnology and biosafety
legislation once it's brought to Parliament to help speed up the process of
introducing improved seeds to local farmers."] The article can be viewed online

1.22 US$3m for global survey of how
science helps farming
A global effort to assess how science can
improve agriculture has received a US$3 million boost thanks to a grant made by
the World Bank last week (29 March).
The International Assessment of Agricultural
Science and Technology for Development (IAASTD) will evaluate the relevance
and effectiveness of different agricultural technologies, from traditional
irrigation techniques to genetically modified crops.
"We need to make
informed decisions now in order to meet the future needs of growing populations
and changing diets, and to improve the health and wellbeing of poor people," said project director Robert Watson in a press release.
"These decisions
must also protect the environment and ensure broad-based economic growth," added
Watson, who is the World Bank's chief scientist.
The three-year project
aims to give policymakers robust information on how science can improve
agriculture and contribute to sustainable development.
It will assess the
impacts of new and existing technologies, highlight key uncertainties and risks,
and identify priorities for research and investment.
The project, which
involves governments, researchers, businesses and civil society groups from
around the world, will produce global and regional reports in much the same way
as the recent Millennium Ecosystem Assessment which Watson co-chaired (see Healthy
ecosystems 'critical in fight against poverty').
Its initial reports
will be made public by the end of 2007.
The new grant from the World Bank's
Global Environment Facility will be supplemented with US$7.5 million from other
donor agencies, including the UN Food and Agriculture Organization
(FAO).
Shivaji Pandey, chair of FAO working group on biotechnology, says more
political commitment is needed to make science and technology integral to
development strategies.
He told SciDev.Net that developing countries should
invest more in agricultural research and technology development because of their
high rates of return.

10-year CLIMA breeding program makes grasspea a safe animal
feed
Western Australia
A high protein, low cost grain legume,
known as grasspea, will push into drought prone and waterlogged areas of Western
Australia for the first time after the release of Australia’s first commercial
variety, Ceora.
A resilient, drought tolerant feed and forage crop, it
can be planted late in autumn, meaning growers can let weeds emerge at the break
of season and spray them off, before seeding Ceora.
Its release marks the
end of a 10-year breeding program to make Ceora a safe animal feed by reducing
levels of the neurotoxin ODAP, which naturally occurs in the Lathyrus genus,
which includes grasspea.
With ODAP levels in Ceora well within animal
safety limits, researcher on the Centre
for Legumes in Mediterranean Agriculture (CLIMA) project, Colin Hanbury
explained that Western Australia's animal and grain producers could now access
some of the crop’s many agronomic advantages.
“Grasspea is a common food
source in drought-stricken environments of Ethiopia, North Africa and the Indian
sub-continent, so it’s well adapted to marginal conditions.
“It’s also
much more tolerant to waterlogging than existing grain legumes and so growers
can introduce valuable rotations to enrich soils in such areas for the first
time,” Dr Hanbury said.
When used as a green manure in Department of
Agriculture and Food, Western Australia (DAFWA) trials, grasspea lifted
subsequent cereal yields by up to 20 per cent.
Dr Hanbury reassured
growers that Ceora’s poisonous past was well behind it, with Grains Research and
Development Corporation, Rural Industries Research and Development Corporation
and CLIMA supported research reducing ODAP levels to a quarter of the recognised
0.2 per cent safe level.
“CSIRO trials showed sheep liveweight gain per
kilogram was greater than on lupins, while non-ruminants, such as pigs and
poultry, could be safely fed Ceora,” he said.
Dongara graingrower, Chris
Gillam, bulked up Ceora last season on alkaline (pH 7.0) soils that received
400mm of growing season rainfall.
“It established quite easily in our
zone at a seeding rate of about 35-40kg/ha and displayed good early vigour
which, because of the plant’s prostrate growth, meant it competed well with
weeds and could block them out.
“We had a very good growing season, but
were hampered by sclerotinia disease and so growers should avoid following
canola too closely in the rotation. We harvested 1.5 t/ha, despite the disease,” Mr Gillam said.

1.24 Association among pollen grain features to maximise
reproductive fitness: A study in Dianthus
species
Tejaswini, Department of Genetics and Plant Breeding,
G.K.V.K., University of Agricultural Sciences, Bangalore
560064
Summary
Components of pollen fitness and variability
result in non-random fertilisation with respect to pollen genotype.
Variability in pollen fitness may be due to several factors of which pollen
grain size, germination capacity and pollen tube growth rate are the major
components. The study taken up in Dianthus spp. reveals
interrelationship among these components so as to maximise the probability of
reproductive success of an individual pollen genotype. Association between
pollen germination percentage and pollen tube growth rate was positive so as to
harness the energy incurred by the parental genotype in production of pollen
grains.
Introduction
Evolution tends to maximise and favor
those characters that support survival. In sexually reproducing organisms,
those features that help to maximise individual’s offspring production are
selected for. Consequently, evolution has the tendency to shape
those features associated with reproduction in such a way as to maximise
individual’s reproductive fitness. Fruit and seed set are the two
important indicators of the reproductive success of plants. Reproductive success
depends on pre-pollination as well as post pollination strategies of an
individual. Number of pollen grains produced, mechanisms of pollen transfer,
mechanisms evolved to attract pollinator can be considered as pre pollination
strategies of plant contributing for its reproductive fitness. Similarly,
size of pollen grains, germination percentage and pollen tube growth rate can be
considered as important post pollination strategies of plant towards its
reproductive fitness. Variation among plants within species is observed
for pollen grain size, germination percentage and pollen tube growth
rate.
The present study tries to evaluate the interrelation among size,
germination percentage and pollen tube growth rate to understand the process of
maximisation for reproductive fitness in the post pollination
stage.

1.25 CIMMYT develops herbicide resistant
maize hybrids
The International Maize and Wheat Improvement Center
(CIMMYT), in collaboration with public and private partners, has developed and
tested 26 Imidazolinone-resistant (IR) 3-Way maize hybrids, across 18 sites in
several sub-Saharan African countries. These hybrids are available to National
Agricultural Research Systems (NARS) and seed companies in eastern and southern
Africa companies for inclusion into trials to decide on variety registration,
release, and eventual commercialization in various sub-Saharan African
countries.
Imidazolinone-resistance (IR) is a natural form of herbicide
resistance originally discovered in mutation-derived populations. Imidazolinone
herbicides possess high biological potency at low application rates, and thus
are an attractive alternative for weed control. The seed of IR-hybrids coated
with Imidazolinone offers an effective protection against Striga, a flowering
parasitic plant with devastating effects on crop production in sub-Saharan
Africa. In trials, IR-hybrids show a 50% increase in yield and provide close to
100% Striga control. Without Imidazolinone seed treatment, the same hybrids can
be commercialized in non-Striga affected areas.

1.26 Papaya ripening genes identified
Papaya is an
important fruit for the tropics, where it is used in both the food and cosmetics
industries. As a result, studies are on the way on the the papaya's genome, in
order to identify candidate genes that may be used to improve the nutritional
quality of papaya through marker-assisted breeding or genetic engineering. Luke
C. Devitt and colleagues of the Queensland Agricultural Biotechnology Center
contribute their findings as they report the "Discovery of genes associated with
fruit ripening in Carica papaya using expressed sequence tags." Their
work appears in a recent issue of Plant Science.
To identify genes
involved in papaya fruit ripening, researchers generated a total of 1171
expressed sequence tags (ESTs) from clones of two independent fruit cDNA
libraries derived from yellow and red-fleshed fruit varieties. ESTs are short
DNA fragments of expressed genes. They have been used extensively and
effectively in a number of fruit species as a tool for rapid gene
discovery.
Researchers found that the most abundant gene sequences
isolated were those coding for the enzymes chitinase, which breaks down chitin;
1-aminocyclopropane-1-carboxylic acid (ACC) oxidase, which controls the release
of ethylene in plants; catalase, which breaks down harmful hydrogen peroxide
into hydrogen and water; and methionine synthase, which processes amino acids.
Researchers also found putative genes contributing to fruit softening, among
them cell wall hydrolases, cell membrane hydrolases, and ethylene synthesis and
regulation sequences. By comparing ESTs with gene sequences in other plant
species, researchers identified expressed papaya genes which could play a role
in fruit aroma and color.

1.27 Research analyzes wild rice diversity
Rice is an
important crop to many economies worldwide, but is constantly plagued by fungal
diseases and insect pests. To protect rice varieties, scientists turn to the
crop's wild relatives, which harbour genes that may protect their domesticated
counterparts from destruction and damage. One such wild rice is Oryza
granulata, which has genes for immunity against bacterial blight, and for
tolerance to shade and seasonal drought. O. granulata, however, is
difficult to cross with cultivated rice, and is threatened with extinction due
to disturbance of its habitat. To contribute to conservation efforts for O.
granulata, Wei Qian and colleagues of the Chinese Academy of Sciences
carried out studies on the "Genetic diversity in accessions of wild rice
Oryza granulata from South and Southeast Asia." Their work appears in a
recent issue of Genetic Resources and Crop Evolution.
The scientists used
Random Amplification of Polymorphic DNA PCR (RAPD-PCR) to assess the genetic
variability among 23 accessions of O. granulata collected from main
distribution areas worldwide. RAPD-PCR makes use of short primers which anneal
to an organism's genome at random. This PCR technique generates hundreds of
sequences of different lengths, which in turn generate a DNA or profile that can
differentiate within and between species. The authors report that RAPD-PCR
analysis of Oryza granulata reveals moderate to high levels of genetic
variation in the wild rice species. The researchers thus suggested that
population studies should be done to further research in wild rice conservation,
a feat which could be achieved by international cooperation amongst rice
geneticists.

1.28 Selection of potato lines resistant to multiple
pathogens
Potatoes rank number four in the list of world food crops
(after rice, wheat and maize), and are grown worldwide. Potatoes are however
affected by numerous diseases, which threaten potato crop production, in
particular by small-scale, resource-poor farmers in developing countries who
lack access to chemical controls and certified disease-free seeds. Classical
breeding for resistance to pathogens involves the identification of resistance
genes, often harboured by wild relatives of cultivated species. These genes are
introgressed into cultivars by crossing the "donor parent", which carries the
resistance gene, to the "recipient parent" to be improved. The resulting progeny
is then repeatedly backcrossed to the "recipient parent" to remove unwanted
genes carried by the "donor parent". Knowledge of the genetic position of the
desirable traits and of closely linked DNA-based markers allows the targeting of
specific genes for introgression, and provides a fast track to increase genetic
gain in crop breeding programs. This technique is known as marker assisted
selection.
Researchers at the Max-Planck Institute for Plant Breeding
Research have developed potato lines that harbor multiple resistance genes by
marker assisted selection, described in the report "Marker-assisted combination
of major genes for pathogen resistance". The article is published in the Online
First section of the journal Theoretical Applied Genetics. The lines generated
are resistant to four important potato pathogens: the Potato Virus Y, the
soilborne fungus Synchytrium endobioticum (responsible for potato wart),
and the root cyst nematodes Globodera rostochiensis and Globodera
pallida. The selected plants can be used as sources of multiple resistance,
and they are available from the IPK (Institut für Pflanzengenetik und
Kulturpflanzenforschung) potato germplasm bank maintained at 18190
Groß-Lüsewitz, Germany.

1.29 Silicon transporter identified in
rice
Silicon is the second most abundant element present on the
earth's crust, and is a very important element for plants. Silicon benefits
plants in many ways: it improves the rate of absorption of many important plant
nutrients; it decreases susceptibility to attack by fungal pathogen and insects
by stimulating the plant's defense mechanisms and by contributing to the
strength and thickness of cell walls; it helps plants to grow on the presence of
salt and heavy metals contaminants; and it protects the plant against damage
from UV rays. Silicon has been used for centuries in agriculture as a fungicide,
mainly in the form of horsetail extract.
Plants differ however widely in
their silicon content, and this difference is related to varying abilities of
different species to take up silicon from soil through their roots. Although
silicon can represent 5% and above of the dry weight of grasses, such as rice,
most dicotyledonous plants, which comprise many important crops, are unable to
accumulate silicon at levels sufficient to be beneficial. How do plants absorb
silicon? Until now, scientists have been unable to answer this question. This
week, a collaborative effort between researchers belonging to several research
institutions in Japan has provided a major breakthrough in the field of plant
silicon. The team describes the first gene important for silicon uptake to be
identified in higher plants: Low silicon rice1 or Lsi1. Their
report, entitled "A silicon transporter in rice" is published in the latest
issue of the scientific journal Nature.
Rice plants with reduced or
impaired Lsi1 gene activity are very susceptible to attack by pathogens
and insects, and have a severely reduced grain yield (1/10 of the yield of non-
mutants). The authors show that the Lsi1 gene encodes a protein that is
localized in the membrane of root cells and is necessary for the uptake of
silicon. This discovery will have tremendous implications for agriculture, as it
opens the way to crop improvement initiatives aimed at providing important food
crops with the tool required to absorb silicon.

CIAT identifies a more nutritious cassava
variety
Scientists in the International Center for Tropical
Agriculture (CIAT) have identified Col 2436, an improved variety of yuca
(cassava)with about three more times protein content in roots compared to normal
varieties, combined with twice the amount in provitamin-A carotenoids.
Therefore, this variety can be of incalculable value to improve the nutrition of
many rural communities, especially in Africa, where cassava is the main food
crop. The variety can also be used for the production of feeds, as it will
reduce the need for protein additives.

the objective of designing strategies to strengthen national and regional
abilities to use plant genetic resources for food and agriculture. A number of
draft reports on national plant breeding and biotechnology surveys are now
available on the web (for Ethiopia, Kazakhstan, Sri Lanka, Tajikistan and
Uzbekistan). In addition, FAO, in collaboration with the International Maize and
Wheat Improvement Center (CIMMYT) and the International Center for Agricultural
Research in the Dry Areas (ICARDA), recently carried out a series of workshops
in Central Asian countries on designing strategies to strengthen the sustainable
use of plant genetic resources. Draft reports from the workshops held in
Uzbekistan (6 April 2006) and Tajikistan (8 April 2006) are now available. For
both the national surveys and the workshop reports, see the "what's new" section

WIPO database – PatentScope
In April 2006, the World Intellectual
Property Organization (WIPO) upgraded its online database, PatentScope, so that
over 1.2 million international applications filed under WIPO's Patent
Cooperation Treaty (PCT) from 1978 to the present are now available in fully
searchable form for free consultation. The information may be searched in
several ways e.g. using keywords (such as 'biotechnology' or 'et/biotechnology'
[i.e. with the word biotechnology in the english title]), names of applicants or
dates and complete documents may be printed or downloaded. Together with
documents on each patent application (e.g. description, claims), the database
gives access to information on the status of the application. PatentScope is a
valuable technical resource as new technologies are often disclosed for the
first time as international patent applications and the patent applications
filed under the PCT system are typically those that inventors consider to be the
most valuable and therefore worth patenting internationally. See http://www.wipo.int/patentscope/ or
contact publicinf@wipo.int for more information. WIPO is one of the United
Nations specialised agencies. It administers 23 international treaties dealing
with different aspects of intellectual property protection and has 183 member
nations.

of intellectual property rights in the sharing of benefits arising from the use
of biological resources and associated traditional knowledge", prepared by A.K.
Gupta. This 164-page publication uses 3 detailed case studies from Nigeria,
India and Mali to consider the role of the existing intellectual property system
in providing benefit-sharing mechanisms for local communities and individual
innovators. The case study in Mali deals with a voluntary initiative for sharing
benefits through the licensing, and possible commercialisation, of a cloned gene
(Xa21) derived from a wild rice variety obtained from Mali, via international

Economic impact of transgenic crops in developing
countries
ABSTRACT
Transgenic crops are being adopted rapidly at
the global level, but only a few developing countries are growing them in
significant quantities. Why are these crops so successful in some countries but
not in others? Farm level profitability ultimately determines whether farmers
adopt and retain a new technology, but this depends on much more than technical
performance. Recent economic studies in developing countries find positive, but
highly variable, economic returns to adopting transgenic crops. These studies
confirm that institutional factors such as national agricultural research
capacity, environmental and food safety regulations, intellectual property
rights and agricultural input markets matter at least as much as the technology
itself in determining the level and distribution of economic benefits.

The First Decade of Genetically Engineered Crops in the
United States
By Jorge Fernandez-Cornejo and Margriet Caswell, with
contributions from Lorraine Mitchell, Elise Golan, and Fred Kuchler
Economic Information Bulletin No. (EIB-11) 36pp, April 2006
Ten
years after the first generation of genetically engineered (GE) varieties became
commercially available, adoption of these varieties by U.S. farmers is
widespread for major crops. Driven by farmers' expectations of higher yields,
savings in management time, and lower pesticide costs, the adoption of corn,
soybean, and cotton GE varieties has increased rapidly. Despite the benefits,
however, environmental and consumer concerns may have limited acceptance of GE
crops, particularly in Europe.
This report focuses on GE crops and their
adoption in the United States over the past 10 years. It examines the three
major stakeholders of agricultural biotechnology and finds that:
1. the pace
of R&D activity by producers of GE seed (the seed firms and technology
providers) has been rapid,
2. farmers have adopted some GE varieties widely
and at a rapid rate and benefited from such adoption, and
3. the level of
consumer concerns about foods that contain GE ingredients
varies by country,
with European consumers being most concerned.

The national
investment in plant breeding is declining. Is this cause for concern? What
are constructive responses? The Plant Breeding Coordinating Committee is being
organized as a permanent forum for leadership regarding this and other issues,
problems, and opportunities of long-term strategic importance to the public and
private plant breeding profession and to the U.S. national plant breeding effort
as a whole.
Participants in this national workshop will:
1) organize
the Plant Breeding Coordinating Committee, including first election of officers;
and,
2) provide the Plant Breeding Coordinating Committee with guidance for
its initial work.
Keynote speakers will look at plant breeding in the context
of our national goals for agriculture:
-Excellence in science and
technology.
-A competitive agricultural system in the global economy
-A
safe and secure food and fiber system
-A healthy, well-nourished
population
-Harmony between agriculture and the environment
-Economic

2006-2008. Plant Breeding Academy, University of California,
Davis.
The University of California Seed Biotechnology Center
would like to inform you of an exciting new course we are offering to teach the
principles of plant breeding to seed industry personnel.
This two-year
course addresses the reduced numbers of plant breeders being trained in academic
programs. It is an opportunity for companies to invest in dedicated personnel
who are currently involved in their own breeding programs, but lack the genetics
and plant breeding background to direct a breeding program. Participants will
meet at UC Davis for one week per quarter over two years (eight sessions) to
allow participants to maintain their current positions while being involved in
the course.
Instruction begins Fall 2006 and runs through Summer
2008 (actual dates to be determined)

7. EDITOR'S NOTES
Plant Breeding News is an electronic forum for the
exchange of information and ideas about applied plant breeding and related
fields. It is published every four to six weeks throughout the year.
The
newsletter is managed by the editor and an advisory group consisting of Elcio
Guimaraes (elcio.guimaraes@fao.org), Margaret Smith (mes25@cornell.edu), and
Anne Marie Thro (athro@reeusda.gov). The editor will advise subscribers one to
two weeks ahead of each edition, in order to set deadlines for
contributions.
REVIEW PAST NEWSLETTERS ON THE WEB: Past issues of the
Plant Breeding Newsletter are now available on the web. The address is: http://www.fao.org/WAICENT/FAOINFO/AGRICULT/AGP/AGPC/doc/services/pbn.html
Please note that you may have to copy and paste this address to your
web browser, since the link can be corrupted in some e-mail applications. We
will continue to improve the organization of archival issues of the newsletter.
Readers who have suggestions about features they wish to see should contact the
editor at chh23@cornell.edu.
Subscribers are encouraged to take an active
part in making the newsletter a useful communications tool. Contributions may be
in such areas as: technical communications on key plant breeding issues;
announcements of meetings, courses and electronic conferences; book
announcements and reviews; web sites of special relevance to plant breeding;
announcements of funding opportunities; requests to other readers for
information and collaboration; and feature articles or discussion issues brought
by subscribers. Suggestions on format and content are always welcome by the
editor, at pbn-l@mailserv.fao.org. We would especially like to see a broad
participation from developing country programs and from those working on species
outside the major food crops.
Messages with attached files are not
distributed on PBN-L for two important reasons. The first is that computer
viruses and worms can be distributed in this manner. The second reason is that
attached files cause problems for some e-mail systems.
PLEASE NOTE: Every
month many newsletters are returned because they are undeliverable, for any one
of a number of reasons. We try to keep the mailing list up to date, and also to
avoid deleting addresses that are only temporarily inaccessible. If you miss a
newsletter, write to me at chh23@cornell.edu and I will re-send it.
