root cells of Arabidopsis thaliana For plants, the only way to grow is for cells to expand. Unlike animals, cell division in plants happens only within a tiny region of the root and stem apex. But just how plants regulate cell growth at the molecular level using the genes, receptors and hormones that govern the process has been something of a black box. Now, a team of scientists from the University of Wisconsin reports the discovery of a hormone and receptor that control cell expansion in plants. Full Story
