AP2 — Triticum aestivum

Summary

TRAESCS3D02G039000 (TaAP2, AP2) on wheat chromosome 3D encodes an AP2/ERF domain-containing protein with DNA-binding transcription factor activity and transcription cis-regulatory region binding. It is associated with numerous biological processes including antifungal innate immune response, photoprotection, photoperiodism, meristem development, jasmonic acid and fatty acid anabolism, the GABA shunt, carbohydrate and lipid transport, glucose and sucrose metabolism, glutathione metabolism, photorespiration, detoxification, virus-induced PTGS, and syngamy. The gene is associated with a wide range of agronomic traits including grain weight, grain number, grain length, grain size, grain yield, spike length, grains per spike, plant height, anther extrusion, stem elongation, anthesis time, seed shape, pollen fertility, sporogenesis, floral organ identity, drought tolerance, and stripe rust. Studies of related genes in other species further connect the family to seed weight, panicle architecture, and stress responses.
