MYB — Triticum turgidum subsp. durum

Summary

TRITD1AV1G045080, designated TtMYB on durum wheat chromosome 1A, encodes a protein with a Myb/SANT domain and homeodomain-like superfamily fold, annotated with DNA binding transcription factor activity, RNA polymerase binding, metallopeptidase activity, and transcriptional co-regulator functions. The gene is associated with circadian rhythm regulation, photoperiodic flowering, anthocyanin and flavonoid biosynthesis, green leaf volatile production, and mycose metabolism. It is linked to seed development, cell wall organization, and responses to salt and abiotic stimulus. Associations with grain weight, protein content, coleoptile length, photosynthetic rate, manganese concentration, drought tolerance, and temperature stress response trait have been observed. Related genes in other species are linked to circadian clock period, thermotolerance, hypocotyl elongation, and photoperiodic flowering time.
