HORVU.MOREX.R3.5HG0486380 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0486380 (ABF1, also known as HvABF1, HvABF2, HvBZIP23, HvBZIP67, HvBZIP46, HvABF3, HvABF4, ABF3, ABF4, DPBF1, DPBF2, DPBF5, and ABI5) on barley chromosome 5H encodes a bZIP domain-containing protein with DNA-binding transcription activator activity. It is associated with regulation of abscisic acid anabolism, TOR signaling, nitrate assimilation, chlorophyll breakdown, and salicylic acid metabolism. The gene has been linked to numerous agronomic traits including endosperm storage protein content, seed protein content, seed color, linoleic and linolenic acid content, inflorescence length, vegetative vigor, leaf elongation rate, water stress response, photoperiod sensitivity, iron content, and responses to various nutrient sensitivities. It localizes to the THO complex, PP2A complex, mediator complex, chromatin, and nuclear envelope. Related genes in other species are associated with drought, salinity, cold tolerance, ABA signaling, seed germination, grain yield, and root growth.
