ABF1 — Brachypodium distachyon

Summary

BdABF1 (BRADI_3G38200V3) on Brachypodium distachyon chromosome 3 encodes a bZIP transcription factor with DNA-binding transcription activator activity and additional annotated molecular functions including aromatic aminotransferase activity, calcium-dependent protein kinase activity, and protein phosphatase regulator activity. The gene is associated with the positive regulation of TOR signaling, regulation of nitrate assimilation, upregulation of chlorophyll breakdown, and pre-harvest sprouting. It is linked to abscisic acid and gibberellin signaling, drought resistance, cold stress, salinity tolerance, and ER stress responses. Associations also include traits such as inflorescence length, seed protein content, vegetative vigor, leaf elongation rate, photoperiod sensitivity, iron and nitrogen sensitivity, and endosperm storage protein content. The product localizes to the THO complex, PP2A complex, mediator complex, chromatin, and nuclear envelope. Studies of related genes in other species link the family to abiotic stress tolerance, yield, grain traits, and root growth.
