ABF1 (OS06G0211200) — Oryza sativa Japonica

Summary

Rice gene ABF1 (BZIP46, Os06g0211200) encodes a bZIP transcription factor with DNA-binding transcription activator activity, along with annotated associations to aromatic aminotransferase, calcium-dependent protein kinase, and protein phosphatase activities. This gene is linked to abscisic acid signalling and abscisic acid-induced growth arrest, as well as leaf senescence, abiotic stress responses, and signal transduction. It has been associated with the regulation of seed dormancy, chlorophyll breakdown, nitrogen fixation, C4 photosynthesis, TOR signalling, and root system development. Associations with agronomic traits include seed length, seed protein content, endosperm storage protein content, linoleic and linolenic acid content, tuberous root weight, inflorescence length, vegetative vigour, iron content, and responses to water stress, salinity, drought, cold, and various nutrient sensitivities. The protein is localised to the nucleus, chromatin, mediator complex, and vesicle compartments.
