MYB (TRAESCS3B02G407700) — triticum aestivum

Summary

TRAESCS3B02G407700 (TaMYB, also known as TaDIV2, TaMID1-3B) on wheat chromosome 3B encodes a MYB-family transcription factor with DNA-binding, protein homodimerization, and zinc-binding activities. The gene is associated with negative regulation of abscisic acid biosynthesis, antifungal innate immune response, photoprotection, photoperiodism, cellular auxin homeostasis, brassinosteroid anabolism, and pre-harvest sprouting. It has been linked to grain iron and zinc content, grain density, grain texture, grain color, seminal root length, leaf lamina length, culm solidness, drought sensitivity, stem rust, and harvest index. The product localizes to mitochondria and cytosol. Studies of related genes in other species connect the family to drought tolerance, abscisic acid sensitivity, and yield-related traits.
