Same with the tomato that everyone was scared of, it was missing the rot gene. ] You'll find I'm right about the genetics. The resistance was accomplished by the INSERTION of a bacterial gene by viral infection (this is the normal mechanism of gene insertion). Here is a reference: psrast.org The pesticide 'Roundup' works by inhibiting an enzyme that is necessary for the plant to synthesise certain aromatic amino acids, killing the plant. The targeted enzyme is called 5-enolpyruvyl shikimate-3-phosphate synthetase, or EPSPS. The genetic modification in Roundup Ready soybeans involves incorporating a bacterial version of this enzyme, (from Agrobacterium species, strain CP4) into the soybean plant, giving the soybean protection from Roundup. In this way, the soybeans and any weeds can be sprayed with Roundup, killing the weeds and leaving the soybeans. Because of the way that this gene was incorporated into soybeans, several other genes are also present. They are: the cauliflower mosaic virus 35S promoter, the EPSPS chloroplast transit protein (CTP) sequence from petunias and the 3' untranslated region of the nopaline synthetase gene (NOS3').
