Modified crops reveal hidden cost of resistance

Genetically modified squash plants that are resistant to a debilitating viral disease become more vulnerable to a fatal bacterial infection, according to biologists.

Prof. Andrew Stephenson, Penn State: There is concern that when the transgenes that confer resistance to these viral diseases escape into wild populations, they will (change) those plants. That could impact the biodiversity of plant communities where wild squash are native.
