Phytochrome B

A plant photo regulatory protein that exists in two forms that are reversibly interconvertible by LIGHT. In response to light it moves to the CELL NUCLEUS and regulates transcription of target genes. Phytochrome B plays an important role in shade avoidance and mediates plant de-etiolation in red light.

Photophobia (Light Sensitivity) 01/01/2020 - "PHOTOPERIODIC CONTROL OF HYPOCOTYL 1 (PCH1) and PCH1-LIKE (PCHL) were shown to directly bind to phytochrome B (phyB) and suppress phyB thermal reversion, resulting in plants with dramatically enhanced light sensitivity. " 01/01/2011 - "Altered dark- and photoconversion of phytochrome B mediate extreme light sensitivity and loss of photoreversibility of the phyB-401 mutant." 05/01/2000 - "A new type of mutation in the plant photoreceptor phytochrome B causes loss of photoreversibility and an extremely enhanced light sensitivity." 12/01/2018 - "In these accessions, natural variants of phytochrome B were found to cause both decreased light sensitivity and lower phosphate uptake. "
2.	Starvation 09/01/2015 - "Rice Phytochrome B (OsPhyB) Negatively Regulates Dark- and Starvation-Induced Leaf Senescence." 03/11/2022 - "Seedlings growing under light deprivation, as often experienced in severe shading or night darkening, exhibit an accelerated senescing process, which is mediated by a complex signaling network that includes sugar starvation responses and light signaling events via the phytochrome B (phyB)-PHYTOCHROME-INTERACTING FACTOR (PIF) signaling routes. "
3.	Hypersensitivity (Allergy) 09/01/2012 - "This red light hypersensitivity can be overcome by eliminating phytochrome B (phyB) and phyD, indicating that LRB1/2 act downstream of these two photoreceptor isoforms. "
