MYB — Triticum aestivum

Summary

TRAESCS3A02G308500, designated TaMYB on bread wheat chromosome 3A, encodes a protein with Myb and SANT domains and has DNA-binding and transcriptional co-regulator activity. The gene is associated with diverse biological processes including circadian regulation, photoperiodism, photoprotection, and brassinosteroid and cuticle anabolism. It is linked to pre-harvest sprouting, antifungal innate immune response, and metabolism of fructan, glutamate, glucose, sulfur, glutathione, and phosphoglycerides. TaMYB is also associated with grain iron and zinc content, grain protein content, grain yield, test weight, harvest index, stand establishment, plant vigor, drought sensitivity, net photosynthetic rate, quantum yield, and temperature stress response. The protein localizes to the nucleus and is associated with jasmonic acid signaling and polyamine biosynthesis pathways.
