OS02G0766700 — Oryza sativa Japonica

Summary

Rice ABF1 (Os02g0766700, also known as BZIP23) encodes a bZIP transcription factor with DNA-binding transcription activator activity, along with annotated protein phosphatase, kinase, and aminotransferase activities. The gene is associated with abscisic acid signalling and abscisic acid-induced growth arrest, as well as leaf senescence, abiotic stress responses, and signal transduction. It is linked to the regulation of seed dormancy, chlorophyll breakdown, root system development, nitrogen fixation, nitrate assimilation, TOR signalling, and C4 photosynthesis. Associations with agronomic traits include seed length, seed protein content, endosperm storage protein content, linoleic and linolenic acid content, inflorescence length, vegetative vigor, leaf elongation rate, water stress response, iron content, and sensitivity to various metals and alkali soil. Related genes in other species are associated with drought tolerance, cold tolerance, biomass, tuber yield, and grain protein content.
