OS02G0610500 — Oryza sativa Japonica

Summary

OsFG (OS02G0610500) on rice chromosome 2 encodes a CONSTANS-like protein with B-box zinc finger and CCT domains, and is annotated with diverse molecular functions including glutamate-tRNA ligase, protein N-GlcNAc transferase, and histone methylase activities. The gene is associated with flowering time regulation, particularly heading date, as well as growth, domestication, and vegetative and floral development in rice. It is linked to photoperiod sensitivity, grain yield, spikelet number, panicle traits, and grain plumpness. Additional associations include responses to light quality (red/far-red), circadian clock photoentrainment, carotenoid metabolism, chlorophyll breakdown, and stress responses such as water stress and nematode damage. Studies of related genes in other species link the family to flowering time, light responsiveness, drought tolerance, and disease resistance.
