title: Evolution of the channelrhodopsin photocycle model.
abstract: Many processes in green algae are under control of rhodopsin-type photoreceptors, but only a few have been studied at least in some detail in the past. Up to now, functionally and biochemically only the channelrhodpsins ChR1 and ChR2 are characterized. Thus, this short review reports on channelrhodopsin properties with a strong focus on the knowledge about the photoreaction cycle(s).
