PAP3 — Phaseolus vulgaris

Summary

PHAVU_007G206000, also known as PvPAP3, PvPIF3 or PvPOC1, encodes a PIF3-like basic helix-loop-helix transcription factor on chromosome 7 of French bean. The product exhibits transcription regulator activator activity, phytochrome binding, red/far-red light photoreceptor activity, nuclear import signal receptor activity, and ubiquitin ligase substrate adaptor activity. PvPAP3 is associated with positive and negative regulation of the phytochrome signaling pathway, positive regulation of seed maturation, gibberellin biosynthesis, and thermomorphogenesis. It is linked to regulation of auxin biosynthesis, photosynthesis light reactions, salinity response, seed size, and protein breakdown. The gene is associated with numerous traits including grain yield, leaf area, flower diameter, fruit set, seed set, photoperiod sensitivity, heterosis, vegetative vigor, submergence response, and glyphosate sensitivity. Related genes in other species are linked to shade avoidance, circadian rhythm, freezing tolerance, and defense responses.
