MYB — Triticum turgidum subsp. durum

Summary

TRITD1BV1G157080, designated TtMYB, encodes a protein with Myb and SANT domains, DNA binding, transcription cis-regulatory region binding, protein homodimerization, and zinc-binding activities. In durum wheat, this gene is associated with negative regulation of abscisic acid biosynthesis, anthocyanin and flavonoid anabolism, cellular auxin homeostasis, determination of dorsoventral asymmetry, lateral root development, leaf senescence, and responses to salt, sucrose, gibberellin, salicylate, and abiotic stimuli. It is linked to grain weight, protein content, coleoptile length, photosynthetic rate, manganese concentration, drought tolerance, and salt tolerance. The encoded protein localizes to mitochondria, cytosol, and cytoplasm. Related genes in other species are linked to anther development, yield, and enhanced salt tolerance with increased ABA content.
