Arecent report in PNAS by Asahina\udet al. (1) addresses the fascinating\udquestion of tissue repair\udin plants. According to recent\udsuggestions, plants and animals might\udshare cellular mechanisms that allow regeneration\udof tissues after damage (2).\udHowever, plants and animals differ greatly\udin their mode of development and their\udability to respond to damage-inducing environmental\udfactors (3). Terrestrial plants\udcannot move their whole body in response\udto environmental cues, and, because of\udtheir cell walls, they also lack cellular mobility\udwithin the plant. This means that\udplants must regenerate damaged tissue\udthrough cellular regeneration at the point\udof damage. Traditionally, this regeneration\udwas considered to occur by dedifferentiation\udof existing mature cells followed by\udcell division to form callus and differentiation\udto form the cellular constituents of\udthe new tissue, although details of this\udprocess have been questioned recentl
