MYB — Triticum aestivum

Summary

TRAESCS6D02G239800, designated TaMYB on bread wheat chromosome 6D, encodes a MYB transcription factor with DNA-binding, RNA-polymerase-binding and transcriptional co-regulator activities. The gene is associated with circadian regulation of gene expression, photoperiodism, photoprotection, and brassinosteroid and cuticle anabolism. It has been linked to pre-harvest sprouting, antifungal innate immune response, and fructan, glutamate, sulfur and glutathione metabolism. Associations with grain traits include grain iron and zinc content, grain density, test weight, grain shape, grain texture, grain color, and grain yield per plant. The gene is also connected to heading time, days to maturity, harvest index, stand establishment, shoot dry weight, root volume, lateral root number, drought sensitivity, temperature stress response, wheat stripe rust disease response, and mycotoxin content.
