Abstract
Chlamydomonas reinhardtii accurately senses the information provided by light and regulates important cellular functions, including gene expression, sexual life cycle, phototaxis, photosynthesis, and photoprotection, using a network of specialized photoreceptors. It is equipped with a single-copy phototropin, four cryptochromes (one animal-type, one plant, and two DASH cryptochromes), and eight rhodopsin-like proteins (two animal-type rhodopsins, two microbial-type channelrhodopsins that act as light-gated cation-selective ion channels, and four histidine-kinase rhodopsins), as well as the UV-B photoreceptor UVR8. This review summarizes knowledge and recent findings on Chlamydomonas photoreceptors with a focus on their known cellular and physiological functions.
