FAR1 — Brachypodium distachyon

Summary

BdFAR1 (BRADI_4G34550V3) on Brachypodium distachyon chromosome 4 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, negative gravitropism, and leaf senescence. The gene has been linked to traits including grain yield, panicle number, leaf area, vegetative vigor, seed coat hardness, root system morphology, photoperiod-sensitive flowering time, photosynthetic ability, starch grain synthesis, brassinosteroid content, and responses to temperature stress, UV light, aphids, cadmium, and phosphorus uptake. It localizes to the nucleus, cytoplasm, and plasma membrane. 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.
