MYB — Triticum aestivum

Summary

TRAESCS3A02G375500 (TaMYB, also known as TaDIV2, TaMID1, or TaMYB-3A) on bread wheat chromosome 3A encodes a protein with Myb and SANT domains and has DNA binding transcription factor activity, transcription cis-regulatory region binding, protein homodimerization activity, DNA binding, zinc binding, and protein binding. The gene is associated with negative regulation of abscisic acid biosynthesis, pre-harvest sprouting, photoprotection, photoperiodism, cellular auxin homeostasis, brassinosteroid anabolism, and antifungal innate immune response. It is linked to grain iron and zinc content, grain yield per plant, harvest index, test weight, grain protein content, stand establishment, plant vigor, root weight, lateral root number, drought sensitivity, stem rust, cell membrane stability, and reproductive period. The product localizes to mitochondria and cytoplasm and is associated with gibberellin signaling and primary root development pathways. Related genes in other species link the family to salt stress tolerance, ABA sensitivity, and reproductive development.
