FG (OS06G0275000) — Oryza sativa Japonica

Summary

OS06G0275000, also known as SE1, FG, or HD1 in rice, encodes a CONSTANS-like protein containing B-box zinc finger and CCT domains. The gene is associated with a wide range of molecular functions including glutamate-tRNA ligase activity, protein N-GlcNAc transferase activity, histone methylase activities, and red/far-red light photoreceptor activity. In rice, it has been connected to flowering time, heading date, growth, domestication, and vegetative and floral development. The gene is linked to photoperiod response, circadian clock entrainment, carotenoid metabolism, and chlorophyll breakdown regulation. Associations extend to agronomically important traits including grain plumpness, grain yield, spikelet number, panicle traits, seed protein content, and stress responses such as drought tolerance, heat stress tolerance, and disease resistance. Related genes in other species are linked to flowering time regulation, light responsiveness, root architecture, trichome development, and tuberization.
