| Function | 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 and the Pfr form that absorbs maximally in the far-red region. 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 including those encoding the small subunit of ribulose- bisphosphate carboxylase, chlorophyll A/B binding protein, protochlorophyllide reductase, rRNA, etc. It also controls the expression of its own gene(s) in a negative feedback fashion. Involved in the flowering time regulation. {ECO:0000269|PubMed:12468726, ECO:0000269|PubMed:15707897}. |
| Subcellular Location | Cytoplasm {ECO:0000269|PubMed:15707897}. Nucleus, nucleoplasm {ECO:0000269|PubMed:15707897}. Nucleus speckle {ECO:0000269|PubMed:15707897}. Note=Cytoplasmic in darkness, but translocated to the nucleus upon illumination, when associated with PAPP5 into speckles. |
