Phytochromes constitute a family of plant photoreceptors that regulate a wide variety of photomorphogenic processes. They act as photochemical switches that interconvert between the inactive (Pr, red-absorbing) and the active state (Pfr, far-red absorbing form) of the receptor, thereby controlling the recognition by reaction partners of the downstream signalling processes. Our studies are focused on phytochromes from Agrobacterium tumefaciens (Agp1, Agp2).
