Studies of biological light‐sensing mechanisms are revealing important roles for ion channels. Photosensory transduction in plants is no exception. In this article, the evidence that ion channels perform such signal‐transducing functions in the complex array of mechanisms that bring about plant photomorphogenesis will be reviewed and discussed. The examples selected for discussion range from light‐gradient detection in unicellular algae to the photocontrol of stem growth in Arabidopsis . Also included is some discussion of the technical aspects of studies that combine electrophysiology and photobiology.
