RL Gene 85:381-390(1989).
CC -!- FUNCTION: Regulatory photoreceptor which exists in two forms that are
CC reversibly interconvertible by light: the Pr form that absorbs
CC maximally in the red region of the spectrum and the Pfr form that
CC absorbs maximally in the far-red region. Photoconversion of Pr to Pfr
CC induces an array of morphogenic responses, whereas reconversion of Pfr
CC to Pr cancels the induction of those responses. Pfr controls the
CC expression of a number of nuclear genes including those encoding the
CC small subunit of ribulose-bisphosphate carboxylase, chlorophyll A/B
CC binding protein, protochlorophyllide reductase, rRNA, etc. It also
CC controls the expression of its own gene(s) in a negative feedback
CC fashion.
CC -!- SUBUNIT: Homodimer.
CC -!- PTM: Contains one covalently linked phytochromobilin chromophore.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the phytochrome family. {ECO:0000305}.
