ATR2 — Triticum aestivum

Summary

TaATR2 (TRAESCS1A02G193200) on wheat chromosome 1A encodes a transcription factor of the AIB/MYC-like family, with annotated molecular functions including BHLH transcription factor binding, histone binding, and RNA polymerase II cis-regulatory region sequence-specific DNA binding. The gene is associated with regulation of glucosinolate biosynthetic process, cellular response to sulfur starvation, induced systemic resistance, drought recovery, and positive regulation of seed maturation. It is linked to grain iron and zinc content, seed protein content, test weight, stand establishment, wheat leaf rust disease response, anther extrusion, and nitrate content. Related genes in other species link the family to jasmonic acid signalling, defence response, drought tolerance, and seed oil accumulation, as well as bacterial blight resistance and phosphate starvation responses.
