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   -!- SIMILARITY: Belongs to the phytochrome family. {ECO:0000305}.
