ABF1 — Triticum aestivum

Summary

TRAESCS5A02G237200, designated TaABF1 on bread wheat chromosome 5A, encodes a bZIP transcription factor of the BZIP46-like family with DNA-binding transcription activator activity. The gene is associated with regulation of abscisic acid anabolism, positive regulation of TOR signaling, regulation of nitrate assimilation, and upregulation of chlorophyll breakdown. It has been linked to pre-harvest sprouting tolerance, seed protein content, endosperm storage protein content, linoleic and linolenic acid content, vegetative vigor, leaf elongation rate, water stress response, photoperiod sensitivity, iron and nitrogen sensitivity, and inflorescence length. Localisation associations include the THO complex, PP2A complex, mediator complex, chromatin, and nuclear envelope. Studies of related genes in other species link the family to drought, salinity, cold tolerance, leaf senescence, root growth, yield, and storage root yield.
