MYB — Triticum aestivum

Summary

TRAESCS4A02G474100, designated TaMYB on bread wheat chromosome 4A, encodes a protein with Myb and SANT domains and has DNA-binding transcription factor activity, sequence-specific DNA binding, transcription cis-regulatory region binding, RNA polymerase binding, and transcriptional co-regulator activity, localised to the nucleus. The gene is associated with photoperiodism, circadian regulation of gene expression, photoprotection, brassinosteroid and fructan anabolism, antifungal innate immune response, and pre-harvest sprouting. It is also associated with grain iron and zinc content, grain protein content, grain yield per plant, test weight, and harvest index, as well as heading time, plant vigor, stand establishment, drought sensitivity, temperature stress response, net photosynthetic rate, and quantum yield. Related genes in other species are linked to circadian rhythms, photomorphogenesis, flowering time, and heat and cold stress responses.
