MYB — Triticum turgidum subsp. durum

Summary

TRITD6BV1G150850 (TtMYB) on chromosome 6B encodes a protein with Myb and SANT domains, DNA binding transcription factor activity, RNA polymerase binding, and transcriptional co-regulator activity, localised to the nucleus. In durum wheat, TtMYB is associated with circadian rhythm regulation, photoperiodic flowering, seed development, anthocyanin and flavonoid biosynthesis, green leaf volatile production, salt and abiotic stress responses, and cell wall organisation. It has been linked to grain weight, protein content, manganese concentration, coleoptile length, photosynthetic rate, drought tolerance, and flowering time. Related genes in other species are associated with circadian clock function, photomorphogenesis, thermotolerance, cold and heat stress responses, hypocotyl elongation, leaf area, biomass, and phenylpropanoid biosynthesis.
