P — Zea mays

Summary

ZM00001EB014290, symbol P, is a maize gene on chromosome 1 encoding a protein with Myb-rel_proteinP/Y1_C, Myb_TF_plants, Myb_dom, SANT/Myb, and Homeodomain-like_sf domains. The product localises to the nucleus and is associated with sequence-specific DNA binding and transcription regulator activity. This gene is associated with pigment accumulation, including anthocyanin and phlobaphene biosynthesis, and with the shikimate pathway, lignin regulation, and phytoalexin production. It has been connected to pericarp colour and thickness, grain length and size, ear length, leaf dimensions, shoot and root dry weight, anthesis time, and heat tolerance. Associations also include resistance to corn earworm and corn leaf aphid, and flavone and flavanol-anthocyanin content. Studies of related genes in other species link the family to flowering time, drought tolerance, and flavonoid content.
