OECD Unique Identifier details

Commodity: Wheat
Traits: Drought tolerance,Glufosinate tolerance
Name of product applicant: INDEAR S.A.
Summary of application:

Wheat genetically modified by the introduction of the HaHB4 and bar genes, exhibits the phenotype of tolerance to various environmental stresses, including drought tolerance, which allows the plant to maintain and provide an increase in yield under adverse environmental conditions, and confer the phenotype of tolerance to herbicides based on glufosinate-ammonium.
The transcription factor HAHB4 is a product of expression of the HaHB4 gene. The expression of HAHB4 in transgenic plants is able to generate the phenotype of tolerance to drought, but does not trigger in the plant processes foreign to their normal physiological mechanisms. Through the delicate regulation of the response to ethylene and other phytohormones, a series of signaling pathways allow the plant to cope with the lack of water while awaiting the cessation of stress, thus remaining in adequate conditions to continue its growth by improving conditions.
As for the PAT protein, the enzyme encoded by the bar gene, like other L-phosphinothricin-N-acetyl transferases, is highly substrate-specific, and catalyzes the N-acetylation of L-phosphinothricin (L-ppt) . L-Glutamate (the closest analog to L-ppt) and other related compounds (such as methionine-sulphoximine or hydroxylysine) are very poor substrates for this enzyme.

Summary of the safety assessment (food safety):
• Inheritance studies conducted indicated that Mendelian segregation exists. • New expression proteins are expressed in low levels. • It is compositionally equivalent to its non-transgenic counterpart. • No evidence of similarity or homology was found with known toxic proteins. • There is no evidence of expression of known allergenic substances for the proteins expressed in the event. It is concluded that the event is substantially equivalent to its conventional counterpart, therefore, it is as safe and no less nutritious than conventional commercial varieties.
Where detection method protocols and appropriate reference material (non-viable, or in certain circumstances, viable) suitable for low-level situation may be obtained:

Country introduction:

In Argentina, the food and feed risk assessment process of transformation events, as the result of modern biotechnology, is carried out by the National Service for Agrifood Health and Quality (Senasa). The General Office of Biotechnology, is the area responsible for carrying out this task. It has an specific professional team and the advise of a Technical Advisory Committee composed of experts from several scientific disciplines representing different sectors involved in the production, industrialization, consumption, research and development of genetically modified organisms.

Stacked events:

Stacked events with all single events approved, are assessed as a new event, but with much less requirements, always on a case-by-case basis.
