MYB — Triticum turgidum subsp. durum

Summary

TRITD4AV1G258720, designated TtMYB on durum wheat chromosome 4A, encodes a protein with sequence-specific DNA binding, RNA polymerase binding, and transcriptional co-regulator activities. The protein localises to the nucleus and is associated with the regulation of circadian rhythm, photoperiodic flowering, and gene expression, as well as anthocyanin and flavonoid biosynthesis, green leaf volatile production, mycose metabolism, and responses to salt and abiotic stimuli. TtMYB is linked to seed development, cell wall organisation, and grain weight. Associations with flowering time, drought tolerance, photosynthetic rate, coleoptile length, protein content, and manganese concentration have been noted. Studies of related genes in other species connect the family to circadian clock function, thermotolerance, cold and heat stress responses, hypocotyl elongation, and biomass accumulation.
