FAR1 — Brachypodium distachyon

Summary

BdFAR1 (BRADI_2G36810V3) on Brachypodium distachyon chromosome 2 encodes a FHY3/FAR1 family protein with DNA-binding transcription activator activity, phytochrome binding, and far-red light photoreceptor activity. It is associated with responses to red and far-red light, circadian rhythm regulation, photomorphogenesis, anthocyanin metabolism, and negative gravitropism. The gene has been linked to grain yield, panicle number, leaf area, vegetative vigor, photosynthetic ability, photoperiod-sensitive flowering, root system morphology, seed coat hardness, temperature stress response, aphid response, phosphorus uptake, and cadmium concentration. It localizes to the nucleus, cytoplasm, and plasmalemma. Studies of related genes in other species connect the family to far-red light signaling, circadian clock function, chloroplast biogenesis, drought tolerance, and shade avoidance.
