MYB14 — Zea mays

Summary

ZmMYB14 (MYB14) on maize chromosome 3 encodes a DNA-binding transcription factor with a Myb domain and a SANT/Myb domain, belonging to the plant SWI/SNF-associated transcription factor family. It is localized to the nucleus and has sequence-specific DNA-binding activity. The gene is associated with anthocyanin breakdown, pigmentation, flavonoid metabolism, and regulation of phenylpropanoid metabolism, as well as cell dedifferentiation, inositol and polyamine metabolism, proline metabolism, fatty acid elongation, the shikimate pathway, and chloride transport. It is linked to numerous agronomic traits including grain yield, grain weight, grain size, grain volume, plant height, leaf angle, ear length, awn color, pericarp color, seed coat color, anthocyanin content, lignin content, protein content, drought tolerance, salt tolerance, days to heading, germination rate, seed dormancy, mesocotyl length, coleoptile length, callus induction, and cytoplasmic male sterility. Related genes in other species are associated with secondary cell wall biosynthesis, xylem vessel formation, and nematode susceptibility.
