SORBI_3008G043900 — Sorghum bicolor

Summary

SORBI_3008G043900 (SbABF1) on sorghum chromosome 8 encodes a bZIP domain-containing protein with DNA-binding transcription activator activity. It is associated with diverse biological processes including C4 photosynthesis, ear development, pre-harvest sprouting, regulation of abscisic acid anabolism, TOR signaling, and responses to pH, nitrate assimilation, and far-red light. The gene is linked to traits such as seed protein content, seed color, inflorescence length, vegetative vigor, leaf elongation rate, photoperiod sensitivity, water stress response, iron and nitrogen sensitivity, and sprouting tolerance. Localization evidence connects the product to the mediator complex, PP2A complex, chromatin, and nuclear envelope. Studies of related genes in other species link the ABF family to drought, salinity, cold tolerance, ABA signaling, leaf senescence, and yield.
