Photoreceptors in Plant Photomorphogenesis to Date. Five Phytochromes, Two Cryptochromes, One Phototropin, and One Superchrome

Plants are bombarded by a myriad of signals, not just from their physical environment, but from friend and foe alike. As a consequence, they have evolved a remarkably sophisticated system of receptors and signal transduction pathways that generate appropriate responses. That light plays a major
