MYB — Zea mays

Summary

ZM00001EB123770 (ZmMYB, also known as ZmASG4, LCL5, or RVE8) encodes a protein with SANT/Myb and homeodomain-like domains, and is annotated with sequence-specific DNA binding, RNA polymerase binding, and transcriptional co-regulator activities, localizing to the nucleus. In maize, this gene is associated with ear morphogenesis, phloem loading, pigment accumulation, cell dedifferentiation, and regulation of secondary metabolism, as well as carbohydrate, arabinose, fructose, pyruvate, and riboflavin metabolism. It has been linked to numerous agronomic traits including grain size, seed weight, ear diameter and length, cob diameter, leaf width and shape, plant color, anthocyanin and flavonoid content, lignin and cellulose content, nitrogen and protein content, starch content, photosynthetic rate, cold tolerance, germination ratio, root number, and heterosis. Related genes in other species are associated with circadian rhythm, photoperiodic flowering, thermotolerance, and hypocotyl elongation.
