Phytochrome B

PhyB is a regulatory photoreceptor which exists in two forms that are reversibly interconvertible by light: the Pr form that absorbs maximally in the red region of the spectrum (660 nm) and the Pfr form that absorbs maximally in the far-red region (730 nm). Photoconversion of Pr to Pfr induces an array of morphogenetic responses, whereas reconversion of Pfr to Pr cancels the induction of those responses. Pfr controls the expression of a number of nuclear genes. It also controls the expression of its own gene by a negative feedback and is involved in the regulation of flowering time .
