Motile microorganisms react to a host of external stimuli, including light, gravity, the magnetic field of the Earth as well as thermal and chemical gradients, in their habitat in order to select a niche suitable for survival and reproduction. Several forms of light-induced behavior have been described in microorganisms including phototaxis, photophobic responses, and photokinesis. Other functions of photoreceptors are regulation of development and entrainment of circadian rhythms. Basically five types of photoreceptor molecules have been identified in microorganisms: BLUF proteins, cryptochromes, phototropins, phytochromes, and rhodopsins. The photoreceptors can control light-activated ion channels or activated enzymes. The responses to the different stimuli in their habitat can be connected in a complex network of signal transduction chains.
