Soybean 305423


Trait: Transformation of the composition of fatty acids
Inserted gene:
gm-fad2-1-Gen-fragment

Source: soybean (Glycine max)

Function: through the introduction of a copy of its natural gene, the production of the enzyme D12-desaturase in the soybean is blocked (antisense). This enzyme is instrumental in the transformation of oleic acid to linoleic acid. The result: the soybeans have a significantly higher content of oleic acid and, conversely, less linoleic acid. At high temperatures, such as in the case of the tempering of fats or of frying, a portion of the linoleic acid will be transformed into trans fat acids, which are regarded as questionable in regards to health. In the processing of oils from 305423-Soybean, fewer trans fat acids are produced.

Function: the gene codes for the protein ALS (acetolactate synthase), which makes the plant insensitive to certain herbicides. The herbicide resistence is used as a selective marker.

Methods for the genetic modification: Microparticle bombardment of plant cells or tissue.
