A leading industry group has given scientists the go-ahead to build genetically engineered peanuts that could be safer, more nutritious and easier to grow than their conventional version. The work could lead to peanuts that yield more oil for biofuel production, need less rainfall and grow more efficiently, with built-in herbicide and pest resistance — traits that have already been engineered into major crops such as cotton, corn, soybeans and canola. [...] with the two leading peanut-producing countries, China and India, working aggressively on transgenic peanuts, the American Peanut Council and its research arm, the Peanut Foundation, this month approved a major policy change.
