SORBI_3010G081800 — Sorghum bicolor

Summary

SORBI_3010G081800 (SbABF1) on sorghum chromosome 10 encodes a bZIP transcription factor with DNA-binding transcription activator activity, along with annotated functions including aromatic aminotransferase, calcium-dependent protein kinase, protein phosphatase regulator, and phosphorelay response regulator activities. SbABF1 is associated with diverse biological processes such as C4 photosynthesis, regulation of abscisic acid anabolism, TOR signaling, nitrate assimilation, chlorophyll breakdown, ear development, pre-harvest sprouting, and responses to pH and far-red light. The gene is linked to traits including seed protein content, linoleic and linolenic acid content, inflorescence length, vegetative vigor, photoperiod sensitivity, water stress response, iron and nitrogen sensitivity, and sprouting tolerance. Localization evidence connects the product 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, and yield.
