ABF1 (HORVU.MOREX.R3.7HG0663690) — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0663690, designated HvABF1 on barley chromosome 7H, encodes a bZIP transcription factor of the BZIP46-like family. The product is annotated with DNA-binding transcription activator activity and additional molecular functions including aromatic aminotransferase and calcium-dependent protein kinase activities. HvABF1 is associated with the regulation of abscisic acid anabolism, TOR signaling, nitrate assimilation, and chlorophyll breakdown, as well as responses to pH and far-red light. The gene is linked to numerous agronomic traits, including endosperm storage protein content, seed protein content, linoleic and linolenic acid content, inflorescence length, vegetative vigor, leaf elongation rate, iron and nitrogen sensitivity, and photoperiod sensitivity. It is also connected to phenotypes such as abscisic acid and gibberellin signaling. Studies of related genes in other species link the family to drought, salinity, cold tolerance, and yield.
