MYB — Triticum aestivum

Summary

TRAESCS6B02G266800, designated TaMYB on wheat chromosome 6B, encodes a protein containing Myb and SANT domains. The protein localises to the nucleus and is associated with sequence-specific DNA binding, transcription cis-regulatory region binding, RNA polymerase binding, and transcriptional co-regulator activity. TaMYB is associated with circadian regulation of gene expression, photoperiodism, photoprotection, and upregulation of circadian rhythm, as well as brassinosteroid and cuticle anabolism, antifungal innate immune response, and pre-harvest sprouting. The gene is linked to grain iron and zinc content, grain yield per plant, test weight, heading time, harvest index, leaf chlorophyll content, drought sensitivity, and wheat stripe rust disease response. Studies of related genes in other species connect the family to circadian clock period, photoperiodic flowering time, thermotolerance, and anthocyanin biosynthesis.
