This is a relatively new way to get a trait into a crop: taking the plant's own gene and ramping it up," [Allison Snow] said. "We don't know yet if our findings are going to be generalizable, but if they are, it's definitely going to be important."
"Our colleagues developed this novel transgenic trait in rice and we didn't know if it would have a fitness benefit, or a cost, or be neutral," Snow said. "With most types of herbicide resistant genes, there's no benefit to a wild plant unless the herbicide is sprayed. A lot of transgenes in crop plants are either selectively neutral in wild plants or, if they have a benefit, it depends on environmental factors like insects, diseases or herbicides being present."
"It's not always the end of the world if a weed starts to become a lot more common after acquiring a new trait - there may be effective ways to manage that weed," Snow said. "You just can't make sweeping generalizations about genetic engineering, and knowledge from ecological studies like ours can help inform risk assessment and biosafety oversight.
