MYB — Zea mays

Summary

ZmMYB (ZM00001EB389960) on maize chromosome 9 encodes a protein with Myb and SANT domains, also known as Protein REVEILLE 6. It localises to the nucleus and has DNA-binding, transcription factor, RNA polymerase binding and transcriptional co-regulator activities. The gene is associated with ear morphogenesis, pigment accumulation, phloem loading, cell dedifferentiation, and regulation of secondary metabolism, anabolism and carbohydrate anabolism. It has been linked to numerous agronomic traits including grain size, seed weight, cob and ear diameter, leaf width and shape, plant color, anthocyanin, flavonoid, lignin, cellulose, starch, protein and nitrogen content, photosynthetic rate, cold tolerance, germination ratio, root number, heterosis, and potassium uptake. Studies of related genes in other species connect the family to circadian rhythms, flowering time, photomorphogenesis, thermotolerance and stress responses.
