Plant organ growth is not so different from animals
(PHYSorg.com Biology)

For a long time, researchers assumed that cell death occurs mainly during animal organ growth, but not in plant organs. A research group led by Hannele Tuominen from UPSC has now demonstrated that the death of certain cells in the root facilitated the growth of lateral roots. These new findings hint at organ growth of plants and animals might not be so different as thought. The study was published today in the journal Current Biology.
