Phytochrome

Vedclass · Answer

(A) The red-far red light response is a classic photomorphogenic response in plants.This response is mediated by a pigment protein known as Phytochrome.Phytochrome exists in two interconvertible forms: $P_r$ (which absorbs red light) and $P_{fr}$ (which absorbs far-red light).When $P_r$ absorbs red light,it converts to $P_{fr}$,and when $P_{fr}$ absorbs far-red light,it converts back to $P_r$.
