MYB — Triticum turgidum subsp. durum

Summary

TRITD3AV1G047500, designated TtMYB on chromosome 3A of durum wheat, encodes a transcriptional co-regulator with DNA-binding and RNA polymerase-binding activities. The protein localises to the nucleus and is associated with the regulation of circadian rhythm, photoperiodic flowering, and gene expression. TtMYB has been connected to anthocyanin and flavonoid biosynthesis, green leaf volatile production, mycose metabolism, and responses to salt and abiotic stress. Associations with agronomic traits include grain weight, protein content, coleoptile length, photosynthetic rate, manganese concentration, drought tolerance, and temperature stress response. Studies of related genes in other species link the family to circadian clock function, hypocotyl elongation, leaf area, biomass, thermotolerance, and cold stress response.
