ABF1 (SORBI_3003G167700) — Sorghum bicolor

Summary

SORBI_3003G167700 (SbABF1) on sorghum chromosome 3 encodes an uncharacterized protein with DNA-binding transcription activator activity and additional annotated molecular functions including calcium-dependent protein kinase and protein phosphatase activities. The gene is associated with regulation of abscisic acid anabolism, positive regulation of TOR signaling, C4 photosynthesis, ear development, pre-harvest sprouting, and upregulation of chlorophyll breakdown. It is linked to traits including seed protein content, inflorescence length, vegetative vigor, leaf elongation rate, photoperiod sensitivity, water stress response, iron content, and sprouting tolerance. Localization associations include the THO complex, PP2A complex, mediator complex, chromatin, and nuclear envelope. Studies of related genes in other species link the ABF family to drought tolerance, abscisic acid signaling, leaf senescence, and yield.
