MYB — Triticum aestivum

Summary

TRAESCS3D02G368000, designated TaMYB (also known as TaDIV2, TaMID1 or TaMYB-3D) on bread wheat chromosome 3D, encodes a MYB-domain transcription factor with DNA-binding, protein homodimerization and zinc-binding activities. The gene is associated with negative regulation of abscisic acid biosynthesis, cellular auxin homeostasis, brassinosteroid anabolism, photoprotection, photoperiodism, and antifungal innate immune response. It has been linked to pre-harvest sprouting, grain iron and zinc content, grain yield per plant, harvest index, grain protein content, grain density and texture, stem rust, drought sensitivity, net photosynthetic rate, days to flowering, leaf lamina length, coleoptile color, plant vigor, and stand establishment. Localisation evidence connects the product to mitochondria and cytosol. Studies of related genes in other species link the family to drought tolerance, abscisic acid sensitivity, and yield.
