MYB1 — Phaseolus vulgaris

Summary

PHAVU_009G062700, designated PvMYB1 on French bean chromosome 9, encodes a MYB transcription factor with a Myb domain, SANT/Myb domain and homeodomain-like superfamily fold. The product binds sequence-specific DNA, chromatin and RNA polymerase II cis-regulatory regions, and has DNA-binding transcription factor activity. PvMYB1 is associated with regulation of primary metabolic processes, phenylpropanoid metabolism, green leaf volatile biosynthesis, anther and tapetum development, pollen development, cell differentiation, circadian rhythm, and responses to cold, other organisms, thirst and salinity. It localises to the nucleus. Studies of related genes in other species link the family to anthocyanin content and drought tolerance.
