Genetically-Altered Crops Can Produce Tough, Hard-To-Kill Weeds

genic crops, and delay the possible negative consequences, if not prevent them in the first place," said Snow.

One solution might be for scientists to insert genetically-engineered traits into the DNA of the cytoplasm of plant cells, instead of the nucleus. The DNA from the nucleus gets into every pollen grain of a plant, and will travel far and wide on the wind, or hitch a ride with pollinators such as bees. But a gene in the cytoplasm could only be inherited through the seeds of a particular plant.

In the future, Snow wants to study transgenes for insect-resistance. "We want to quantify how much of a benefit there is to a weed that acquires these transgenes," she said. "It's a very basic ecological question, but nobody knows the answer."
