Gene : PHYA A. thaliana

DB identifier  ? AT1G09570 Secondary Identifier  ? locus:2012300
Name  ? phytochrome A Brief Description  phytochrome A
TAIR Computational Description  phytochrome A;(source:Araport11)
TAIR Curator Summary  Light-labile cytoplasmic red/far-red light photoreceptor involved in the regulation of photomorphogenesis. It exists in two inter-convertible forms: Pr and Pfr (active) and functions as a dimer.The N terminus carries a single tetrapyrrole chromophore, and the C terminus is involved in dimerization. It is the sole photoreceptor mediating the FR high irradiance response (HIR). Major regulator in red-light induction of phototropic enhancement. Involved in the regulation of de-etiolation. Involved in gravitropism and phototropism. Requires FHY1 for nuclear accumulation.

PHYA_ARATH PHYA_ARATH-2 developmental stage Accumulates progressively in maturating seeds to reach a peak in dry seeds (PubMed:23708772). Expressed upon seed imbibition (PubMed:23708772).
A0A1P8AVD9_ARATH 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.
PHYA_ARATH PHYA_ARATH-2 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. Can phosphorylate FHY1 and, possibly, FHL, in red light conditions; this inactivates their co-shuttling to the nucleus (PubMed:19208901). Regulates phototropic responses both in the nucleus (e.g. hypocotyl elongation and cotyledon opening under high-irradiance conditions and seed germination under very-low-fluence conditions) and in the cytoplasm (e.g. negative gravitropism in blue light and red-enhanced phototropism) (PubMed:17566111). Promotes seed germination, suppression of hypocotyl elongation, and randomization of hypocotyl growth orientation in far-red light; these responses to far-red light are repressed by UNE10/PIF8 (PubMed:31732705). Stabilizes UNE10/PIF8 but sequesters PIF3/PAP3 from its target genes promoters in far-red light (PubMed:31732705).
A0A1P8AVD9_ARATH PHYA_ARATH PHYA_ARATH-2 similarity Belongs to the phytochrome family.
PHYA_ARATH PHYA_ARATH-2 subcellular location Cytoplasmic in darkness, but translocated to the nucleus upon illumination, when associated with PAPP5 into speckles.
PHYA_ARATH PHYA_ARATH-2 tissue specificity Expressed in fruits, flowers, leaves, stems, seedlings and roots.
