My comments: While it poses a similar problem as approved GMO soybeans because both species self pollinate, profit per acre for wheat is less than corn or soybeans, making the higher cost of GMO wheat seed less attractive to the farmer.
A soybean crop used in foodstuffs is less obvious than bread. “Hey, don’t mess with my bread” is more concerning than “hey don’t mess with the hidden soy in my Doritos. However, I bet Tofu and soy milk consumers are more politically active!
Finally, do we need any more selection pressure on weed populations to select for Roundup resistant strains?
