MYB — Triticum aestivum

Summary

TRAESCS3D02G134000, designated TaMYB on bread wheat chromosome 3D, encodes a MYB-domain transcription factor with sequence-specific DNA binding, RNA polymerase binding and transcriptional co-regulator activities. The gene is associated with circadian regulation of gene expression, photoperiodism, photoprotection, and upregulation of circadian rhythm. It is linked to pre-harvest sprouting, brassinosteroid and cuticle anabolism, fructan and glutamate metabolism, and the antifungal innate immune response. Associations with agronomic traits include grain yield per plant, grain iron and zinc content, grain protein content, test weight, harvest index, radiation use efficiency, plant vigor, stand establishment, drought sensitivity, temperature stress response, and net photosynthetic rate. The product localises to the nucleus and is also connected to lipid transport, sulfur and glutathione metabolism, and chromosome localization.
