MYB — Zea mays

Summary

ZM00001EB366790 (ZmMYB) on maize chromosome 8 encodes a protein with Myb and SANT domains and has DNA binding transcription factor activity, DNA binding, protein homodimerization activity, transcription cis-regulatory region binding, protein binding, and zinc binding activities. This gene is associated with ear morphogenesis, pigment accumulation, cell dedifferentiation, phloem loading, negative regulation of abscisic acid biosynthesis, regulation of secondary metabolism, and regulation of anabolism. It is linked to numerous agronomic traits including ear diameter and length, cob diameter, anthesis-silking interval, grain and seed size, seed weight, starch and flavonoid content, leaf width and color, root number, water use efficiency, photosynthetic rate, cold tolerance, and heterosis. Localization evidence connects the product to mitochondria, cytosol, and cytoplasm. Related genes in other species link the family to salt tolerance, ABA content, panicle dry weight, grain iron and zinc content, and fungal disease response.
