This review focuses on the blue light responses in bacteria and on the bacterial proteins which have been demonstrated to function as blue light receptors. Results of the previous years reveal that different types of photoreceptors have already evolved in prokaryotes. However, for most of these photoreceptors the exact biological functions and the mechanisms of signaling to downstream components are poorly understood.
