AP37 — Triticum aestivum

Summary

TRAESCS3B02G357500 (TaAP37, also known as TaERF4-3B) on wheat chromosome 3B encodes a protein with an AP2/ERF domain, possessing DNA-binding, transcription coactivator and corepressor activities, and protein homodimerization capability. The gene is associated with regulation of ethylene, jasmonic acid, and salicylic acid biosynthetic and metabolic processes, hydrogen peroxide biosynthesis, and defense responses to insects and herbivores. It has been linked to seed size, grain weight, flowering time, plant height, root development, stomatal traits, and responses to drought, high temperature, salinity, and osmotic stress. Additional associations include trichome formation, embryo development, phloem or xylem histogenesis, and light response. Studies of related genes in other species connect the family to pathogen resistance, grain yield, anthocyanin content, and cold tolerance.
