GM Rice Risks Creating Superweeds

"In the first modification of its kind, Japanese researchers have inserted a gene from the human liver into rice to enable it to digest pesticides and industrial chemicals. The gene makes an enzyme, code-named CPY2B6, which is particularly good at breaking down harmful chemicals in the body."

"But scientists caution that if the gene were to escape to wild relatives of the rice it could create particularly vicious superweeds that were resistant to a wide range of herbicides."
