MYB — Zea mays

Summary

ZM00001EB160410 (ZmMYB, also known as ZmASG4, ZmLCL5, or ZmRVE8) on maize chromosome 3 encodes a DNA-binding transcription factor with sequence-specific DNA binding, transcription cis-regulatory region binding, RNA polymerase binding, and transcriptional co-regulator activities, localizing to the nucleus. It is associated with ear morphogenesis, phloem loading, pigment accumulation, cell dedifferentiation, and regulation of secondary metabolism, anabolism, and carbohydrate anabolism. The gene is linked to numerous agronomic traits including ear diameter and length, cob diameter, grain size, seed weight, starch, protein, anthocyanin, flavonoid, lignin, and cellulose content, as well as cold tolerance, photosynthetic rate, nitrogen content, potassium uptake, nitrate transport, germination ratio, heterosis, and plant color. Related genes in other species are associated with circadian rhythm, photoperiodic flowering time, thermotolerance, and hypocotyl elongation.
