PBF — Zea mays

Summary

ZM00001EB094330 (PBF) on maize chromosome 2 encodes a Dof zinc-finger protein that binds DNA and localises to the nucleus. The gene is associated with regulation of endosperm development, nutrient and carbohydrate storage, starch and amylopectin metabolism, and protein processing. It has been linked to grain yield, grain size and weight, seed size and weight, starch and amylopectin content, grain lysine and amino acid content, cold tolerance, and anthesis time. Additional associations include ER stress response, meiosis, double fertilization, auxin anabolism, and nucleosome assembly. Studies of related genes in other species further connect the family to endosperm and grain development.
