B-1 — Sorghum bicolor

Summary

SORBI_3010G260600 (SbB-1) on sorghum chromosome 10 encodes a calcium and calcium/calmodulin-dependent serine/threonine-protein kinase. The gene is associated with diverse molecular functions including hexose, nitrate, and carbohydrate transmembrane transporter activities, potassium:proton antiporter activity, red/far-red light photoreceptor activity, and protein phosphatase activity. It has been linked to biological processes such as response to symbiont, nitrate transmembrane transport, potassium ion homeostasis, regulation of stomatal opening, abscisic acid metabolism, circadian regulation of calcium ion oscillation, and acquisition of seed longevity. Associations with agronomically relevant traits include photosynthetic ability, biomass yield, carotenoid content, photoperiod-sensitive flowering time, water stress response, nitrogen sensitivity, and glyphosate sensitivity. The gene product localizes to multiple cellular compartments including the tonoplast, endosome, Golgi complex, chloroplast stroma, and nuclear envelope.
