What is herbicide resistant soybean by Monsanto?
In growing soybean, well-planned weed and pest control is important to get desired harvest. If soybean itself had herbicide resistance, low input cultivation would be possible and dust cropping could be much simpler. Monsanto had endeavored, in vain, till I 990s to achieve this goal by creating soybean mutant that is resistant to their best selling organo-phosphoric herbicide Roundup in which the glyphosate is the active ingredient. The resistant strains created, however, had seriously hampered enzymatic activity of EPSPS (5-enol-pyruvylshikimate-3-phosphate synthase: one of the enzymes work to synthesize aromatic amino acid, Tyrosine, Phenylalanine and Tryptphan) and the soybean failed to thrive. The genetic engineering technology was becoming popular at the time, and was naturally employed in introducing gene from different organism into soybean. Herbicide resistant bacterium was found in the glyphosate factory sewage of Monsanto USA. This Agrobacterium tumefaciens CP4 strain is a ki
