The idea was that if exposure to herbicides could trigger weeds' selection-pressure response2 and thereby change their receptors to herbicides to block binding and herbicide action, the same change could be made in crops using biotechnology approaches. During this time, DuPont and Monsanto both were working on developing crops that combined superior crop-protection chemistry with superior genetics.
