MYB — Zea mays

Summary

ZmMYB (ZM00001EB288890) on maize chromosome 6 encodes a protein with Myb and SANT domains and is associated with DNA binding, transcription cis-regulatory region binding, protein homodimerization activity, and zinc binding. In maize, it is associated with ear morphogenesis, pigment accumulation, phloem loading, cell dedifferentiation, negative regulation of abscisic acid biosynthesis, and processes including arabinose, fructose, pyruvate, and lipid metabolism. It has been linked to traits such as plant and pericarp color, anthocyanin, flavonoid, lignin, starch, protein, and nitrogen content, seed weight and size, grain size, ear diameter and length, cob diameter, leaf width and shape, root number, germination ratio, photosynthetic rate, cold tolerance, and heterosis. Associations with drought, salt, and abiotic stress tolerance, ABA sensitivity, and seed lipid biosynthesis have also been noted.
