Many animals and plants regenerate tissues or even whole organs after injury. Typically, specialized cells at the wound site revert to a ‘pluripotent’ state–via a process called dedifferentiation—which means they regain the ability to develop into the various cell types required for regeneration. The dedifferentiated cells rapidly divide to form a callus from which the damaged tissue or organ will regenerate. Now, a research team from the RIKEN Plant Science Center in Yokohama has identified a master regulator of the response of plants to injury.
