FG — Brachypodium distachyon

Summary

BdFG (BRADI_3G56260V3) on Brachypodium distachyon chromosome 3 encodes a CONSTANS-like protein with B-box zinc finger and CCT domains, and is associated with multiple molecular functions including glutamate-tRNA ligase activity, protein N-GlcNAc transferase activity, and red/far-red light photoreceptor activity. The gene is linked to photoperiod sensitivity, flowering time regulation, and responses to both long-day and short-day conditions. It has been connected to agronomically important traits including grain yield, spikelet number, stem length, seed protein content, and vegetative vigor. Additional associations include carotenoid metabolism, chlorophyll breakdown regulation, and responses to water stress, nitrogen sensitivity, and pathogen resistance. Studies of related genes in other species link the CONSTANS-like family to heading date, panicle architecture, and stress tolerance in cereals, as well as flowering time and light responsiveness in Arabidopsis.
