Photoresponsive strategy of cyanobacteria

Abstract

Light is not only energy source but also important signal for photosynthetic organisms. Thus, photosynthetic organisms possess highly developed photoresponsive systems to acclimate to changing light environments. Cyanobacteria possess such systems and cyanobacteriochromes play central roles as a photoreceptor. In this review, we introduce cyanobacterial photoresponsive strategy regulated by the cyanobacteriochromes and our recent studies on photoresponsive systems of a unique cyanobacterium Acaryochloris marina.
