MYB — Triticum turgidum subsp. durum

Summary

TRITD7AV1G249660, designated TtMYB on durum wheat chromosome 7A, encodes a protein with Myb and SANT domains, sequence-specific DNA binding, RNA polymerase binding, and DNA binding transcription factor activity, localising to the nucleus. The gene is associated with regulation of circadian rhythm and gene expression, photoperiodism and flowering, seed development, anthocyanin and flavonoid anabolism, green leaf volatile biosynthesis, mycose metabolism, and response to salt and abiotic stimulus. It is linked to grain weight, protein content, coleoptile length, photosynthetic rate, manganese concentration, drought tolerance, and temperature stress response traits. Studies of related genes in other species connect the family to circadian clock period, thermotolerance, hypocotyl elongation, photoperiodic flowering time, leaf area, biomass, and cold stress response.
