MYB — Zea mays

Summary

ZmMYB (ZM00001EB274210) on maize chromosome 6 encodes a protein with a MYB domain, SANT domain, and homeodomain-like superfamily domain, with DNA binding, sequence-specific DNA binding, transcription cis-regulatory region binding, DNA binding transcription factor activity, RNA polymerase binding, transcriptional co-regulator activity, and protein binding, localised to the nucleus. The gene is associated with ear morphogenesis, pigment accumulation, phloem loading, and regulation of secondary metabolism and anabolism. It is linked to numerous agronomic traits including grain size, seed weight, ear diameter and length, cob diameter, anthocyanin and flavonoid content, starch, protein, lignin and cellulose content, photosynthetic rate, cold tolerance, nitrogen content, potassium uptake, nitrate transport, root number, leaf width and shape, plant color, heterosis, and germination ratio. Related genes in other species are associated with circadian rhythm, photoperiodic flowering time, thermotolerance, and hypocotyl elongation.
