B-1 — Sorghum bicolor

Summary

SORBI_3002G12121800 (SbB-1) on sorghum chromosome 2 encodes a protein with myo-inositol transporter domains and myo-inositol:proton symporter activity, hexose transmembrane transporter activity, and other annotated molecular functions. The gene is associated with biological processes including nitrate transmembrane transport, potassium ion homeostasis, abscisic acid metabolism, regulation of stomatal opening, and acquisition of seed longevity. It is linked to traits including photosynthetic ability, biomass yield, carotenoid content, photoperiod-sensitive flowering time, water stress response, root phototropism, and sensitivity to various nutrients and light conditions. The gene product localizes to multiple cellular compartments including the tonoplast, endosome membrane, Golgi complex, chloroplast stroma, and nuclear envelope. Related genes in other species are associated with nitrate and potassium translocation, salt tolerance, cadmium resistance, seed longevity, and root development.
