Signalling pathway regulating plant cell growth identified [Registered]

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, making cell expansion the critical path to increased stature. 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-Madison reports the discovery of a hormone and receptor that control cell expansion in plants. Writing in the journal Science, a group led by…
