MYB — Zea mays

Summary

ZM00001EB355450, designated ZmMYB (also known as ZmASG4, LCL5, or ZmRVE8), encodes the protein REVEILLE 8, a transcriptional co-regulator with DNA-binding and RNA polymerase-binding activity localized to the nucleus. This maize gene on chromosome 8 is associated with ear morphogenesis, pigment accumulation, phloem loading, and the regulation of secondary metabolism, anabolism, and carbohydrate anabolism. It has been linked to numerous agronomic traits including plant and pericarp color, cob and ear diameter, ear length, seed weight and size, grain size, starch and protein content, lignin and cellulose content, nitrogen content, potassium uptake, nitrate transport, photosynthetic rate, cold tolerance, germination ratio and rate, leaf width and shape, root number, lateral root number, callus induction, and heterosis. Associations also connect it to circadian rhythm, flowering time, biomass, cell size, and responses to temperature, salt, and osmotic stress.
