CO (GLYMA_08G255200V4) — Glycine max

Summary

GLYMA_08G255200V4, also known as GmCO, encodes a CONSTANS-like protein containing B-box and CCT domains. The gene is associated with euchromatin binding, protein N-GlcNAc transferase activity, and various photoreceptor activities. GmCO is linked to flower formation, photoperiodism, circadian clock entrainment, and responses to light quality and duration. It has been connected to numerous agronomically relevant traits including photoperiod sensitivity, net photosynthetic rate, vegetative vigor, leaf angle, stem length, iron content, water stress response, and nematode damage response. The gene is also associated with inflorescence branch arrangement, fruit set, seed storage protein content, and heterosis. Related genes in other species link the family to photoperiod-dependent flowering time, drought tolerance, and seed development.
