ABF1 (OS09G0456200) — Oryza sativa Japonica

Summary

OsABF1 (also known as OsbZIP72, OsAREB2, and ABF4) on rice chromosome 9 encodes a bZIP domain-containing protein with DNA-binding transcription activator activity, along with annotated associations to protein phosphatase, kinase, and aminotransferase activities. The gene is linked to abscisic acid signalling and gibberellin signalling, and has been connected to leaf senescence, abiotic stress, oxidative stress, and flower development. It is associated with the regulation of seed dormancy, chlorophyll breakdown, root system development, C4 photosynthesis, phloem loading, and nitrogen fixation. Traits linked to OsABF1 include seed length, seed protein content, inflorescence length, vegetative vigor, leaf elongation rate, water stress response, iron sensitivity, and sprouting tolerance. Related genes in other species are associated with drought tolerance, biomass, and tuber yield.
