from National Public Radio
Special genes inserted into crop plants have a way of leaking into the environment. That much scientists know for sure. What they're less certain about is what effect those genes have on plants growing in the wild.
Andrew Stephenson is interested in answering that question. He's a plant ecologist at Penn State University. Plant breeders put things called transgenes into plants to give them desirable properties such as disease resistance.
