MYB — Triticum aestivum

Summary

TRAESCS1D02G275400 (TaMYB, also known as TaDIV2, TaMID1, or MYB) on bread wheat chromosome 1D encodes a DNA-binding transcription factor with a Myb/SANT domain that localizes to the cytoplasm and mitochondria. 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 connected to numerous grain quality and yield traits including flour yield, starch yield, protein content, seed hardness, vitreousness, dormancy, sprouting tolerance, amylose content, grain weight per spike, and mineral content (iron, zinc, phosphorus). Associations also include drought response, salt stress tolerance, ABA sensitivity, temperature-sensitive male sterility, awn length, flag leaf senescence, and vascular bundle number. Studies of related genes in other species link the family to anther development, yield, and enhanced salt tolerance.
