Antagonistic genes control rice growth

Scientists at the Carnegie Institution, with colleagues, have found that a plant steroid prompts two genes to battle each other -one suppresses the other to ensure that leaves grow normally in rice and the experimental plant Arabidopsis thaliana, a relative of mustard. The results, published in the December 15, 2009, issue of The Plant Cell, have important implications for understanding how to manipulate crop growth and yield.
