PHYC — Brachypodium distachyon

Summary

BRADI_1G08400V3 (BdPHYC) on chromosome 1 of Brachypodium distachyon encodes a phytochrome photoreceptor with red/far-red light photoreceptor activity, histidine kinase activity, and ubiquitin ligase activity. It is associated with photoperiodism, vernalization response, circadian regulation, de-etiolation, chloroplast avoidance movement, anthocyanin and abscisic acid metabolism, and reproductive behavior. The gene is linked to traits including photoperiod-sensitive flowering time, chlorophyll ratio, leaf area, shoot elongation under submergence, photosynthetic ability, temperature stress response, viral disease response, and glyphosate sensitivity. It localizes to the nucleus, cytosol, and plasmalemma, and is part of nuclear ubiquitin ligase complexes. Related genes in other species connect the family to heading date, grain yield, plant height, and photoperiod-dependent flowering.
