FAR1 — Beta vulgaris subsp. vulgaris

Summary

BvFAR1 (BVRB_4G087770) on sugar beet chromosome 4 encodes a DNA-binding transcription activator specific to RNA polymerase II, belonging to the FHY3/FAR1 family with FAR1 DNA-binding, MULE transposase, and zinc-finger PMZ and SWIM domains. The gene is associated with far-red and red light signaling pathways, photomorphogenesis regulation, positive gravitropism, circadian rhythm upregulation, and negative regulation of leaf senescence. It is linked to isoprenoid and flavonoid metabolism, anthocyanin biosynthesis, and abscisic acid-mediated signaling. Associations include traits such as seed coat hardness, root system morphology, light quality responses, seedling hypocotyl length, shoot branching, lateral root number, seed yield, and nutrient uptake (phosphorus, nitrate, iron). Phenotypic connections encompass light response, phosphate starvation, suberin deposition, pathogen resistance, and flowering. The protein localizes to the nucleus.
