C1 — Zea mays

Summary

ZM00001EB373660 (C1, ZmTDMYB7A107) on maize chromosome 9 encodes a protein with a Myb DNA-binding domain and homeodomain-like superfamily fold, possessing sequence-specific DNA-binding and transcription regulatory activity. The gene is directly associated with spikelet anthocyanin pigmentation in maize and with anthocyanin accumulation. Annotated associations link C1 to the positive regulation of anthocyanin anabolism, pigment anabolism, phenylpropanoid anabolism, lignin anabolism, endosperm development, and the shikimate pathway. It is also associated with traits including plant color, leaf color, anthocyanin content, grain size, plant height, drought tolerance, anthesis silking interval, seed dormancy, and chlorophyll content. The encoded protein localises to the nucleus. Studies of related genes in other species link the family to anthocyanin pigmentation and grain color.
