SORBI_3006G190800 — Sorghum bicolor

Summary

SORBI_3006G190800, designated SbABF1, encodes a bZIP transcription activator with DNA-binding transcription activator activity and additional annotated functions including aromatic aminotransferase, calcium-dependent protein kinase, and protein phosphatase regulator activities. In sorghum, SbABF1 is associated with C4 photosynthesis, ear development, pre-harvest sprouting, regulation of abscisic acid anabolism, TOR signaling, chlorophyll breakdown, and responses to pH, far-red light, and water stress. It is linked to traits including seed protein content, seed color, inflorescence length, vegetative vigor, leaf elongation rate, and sensitivities to iron, copper, manganese, nitrogen, and alkali soil. The gene is also associated with endosomal transport, chromatin, the mediator complex, and the PP2A complex. Studies of related genes in other species link the ABF family to drought, salinity, cold tolerance, ABA signaling, leaf senescence, and yield.
