SORBI_3002G225100 — Sorghum bicolor

Summary

SORBI_3002G225100, designated SbABF1, encodes a bZIP transcription activator with DNA-binding transcription activator activity and additional annotated molecular functions including aromatic aminotransferase activity, calcium-dependent protein kinase activity, and protein phosphatase regulator activity. In sorghum, SbABF1 is associated with diverse biological processes such as C4 photosynthesis, ear development, pre-harvest sprouting, regulation of abscisic acid anabolism, TOR signaling, and responses to nitrate assimilation, pH, and far-red light. It is linked to traits including seed protein content, seed color, inflorescence length, vegetative vigor, sprouting tolerance, and sensitivities to iron, copper, manganese, and alkali soil. The gene is also associated with abscisic acid and gibberellin signaling, drought resistance, cold stress, and salinity responses. Related genes in other species are linked to drought tolerance, yield, leaf senescence, and abiotic stress resistance.
