Light impulses can be used to trigger electrical excitation in plants

Optogenetics denotes the manipulation of cellular processes by light-based biological techniques. An international research team led by the Würzburg plant scientists Rainer Hedrich, Georg Nagel and Dirk Becker has succeeded in applying this method to higher plants: Light impulses can now be used to trigger electrical excitation in plants.
