PHAVU_004G046601 — Phaseolus vulgaris

Summary

PHAVU_004G046601, designated PvCO on chromosome 4 of French bean (Phaseolus vulgaris), encodes a CONSTANS-like protein containing a CCT domain. The gene is associated with a wide array of molecular functions including euchromatin binding, protein N-GlcNAc transferase activity, and red and far-red light photoreceptor activity. PvCO is linked to the regulation of flowering, particularly through upregulation of short-day photoperiodism and response to both long and short days, as well as photoentrainment of the circadian clock. It has been connected to numerous agronomic traits including photoperiod sensitivity, vegetative vigor, stem length, leaf angle, fruit set, seed storage protein content, and responses to water stress, nitrate, and glyphosate. Studies of related genes in other species link the family to photoperiod-dependent flowering time, drought tolerance, and seed development.
