FG (OS02G0178100) — Oryza sativa Japonica

Summary

OsFG (Os02g0178100) is a rice gene on chromosome 2 encoding a CONSTANS-like protein with Znf_B-box and CCT domains. It is associated with multiple molecular functions including glutamate-tRNA ligase activity, protein N-GlcNAc transferase activity, histone methylase activities, and red/far-red light photoreceptor activity. The gene is linked to flowering time, heading date, growth, and domestication traits in rice, as well as to grain yield, spikelet number, panicle traits, and plant height. It has been connected to photoperiod sensitivity, responses to long-day and short-day conditions, regulation of phytochrome signaling, carotenoid metabolism, and chlorophyll breakdown. Associations also include grain plumpness, seed protein content, endosperm storage protein content, and stress responses such as water stress, nitrogen sensitivity, and disease resistance.
