AP2-4 — Zea mays

Summary

ZmAP2-4 (ZM00001EB387280) on maize chromosome 9 encodes a protein with an AP2/ERF domain and DNA-binding domain superfamily, and is annotated with DNA binding, transcription cis-regulatory region binding, and DNA binding transcription factor activity. The gene is associated with biological processes including regulation of seed development, endosperm development, floral organ abscission, seed abscission, starch biosynthesis, vegetative phase change, sporangia development, organogenesis, miRNA processing, mRNA breakdown, proteasome degradation, alkane and wax anabolism, mycose biosynthesis, demethylation, digestion, and organelle organization. It localizes to the nucleus and transcription regulator complex. Associations with agronomic traits include grain yield, biomass yield, plant height, anthesis time, tassel branch number, leaf number, floral organ number and identity, meristem identity, phyllotaxy, heterosis, seed color, fruit color, drought tolerance, and salt tolerance, as well as phenotypes related to abscisic acid, stress response, seed germination, and seedling growth.
