MYB — Triticum turgidum subsp. durum

Summary

TRITD7AV1G003710, designated TtMYB on durum wheat chromosome 7A, encodes a protein containing SANT/Myb and homeodomain-like domains. The protein localises to the nucleus and exhibits DNA-binding, RNA polymerase-binding and transcriptional co-regulator activities. TtMYB is associated with circadian rhythm regulation, photoperiodic flowering, anthocyanin and flavonoid biosynthesis, green leaf volatile production, seed development, cell wall organisation, and responses to salt and abiotic stress. The gene is linked to grain weight, protein content, photosynthetic rate, coleoptile length, manganese concentration, drought tolerance and temperature stress response. Studies of related genes in other species connect the family to circadian clock function, thermotolerance, cold stress response, photomorphogenesis, biomass accumulation, leaf area and cell size.
