FAR1 — Brachypodium distachyon

Summary

BdFAR1 (BRADI_4G24666V3) on chromosome 4 of Brachypodium distachyon encodes a FHY3/FAR1 family protein with a FAR1 DNA-binding domain and MULE transposase domain, annotated as a DNA-binding transcription activator and far-red light photoreceptor with histidine kinase and protein kinase activities. It is associated with red/far-red light signaling, circadian clock regulation, photomorphogenesis, anthocyanin metabolism, gravitropism, leaf senescence, and alcohol biosynthesis. The gene is linked to traits including grain yield, panicle number, leaf area, root morphology, photoperiod-sensitive flowering, photosynthetic ability, starch grain synthesis, cadmium concentration, phosphorus uptake, aphid response, seed coat hardness, and temperature stress response. Studies of related genes in other species connect the family to far-red high-irradiance response, circadian clock function, chloroplast biogenesis, drought tolerance, and phosphate deficiency tolerance.
