B-1 — Sorghum bicolor

Summary

SORBI_3006G130800 (SbB-1) on sorghum chromosome 6 encodes a protein with myo-inositol:proton symporter activity, hexose transmembrane transporter activity, and multiple other transport and signaling functions including phosphorelay sensor kinase activity, calcium-dependent protein serine/threonine kinase activity, and protein phosphatase activity. The gene is associated with nitrate transmembrane transport, potassium ion import and homeostasis, monosaccharide transport, abscisic acid metabolism, regulation of stomatal opening, red and far-red light signaling, circadian regulation of calcium oscillation, and acquisition of seed longevity. It is linked to traits including photosynthetic ability, biomass yield, carotenoid content, photoperiod-sensitive flowering time, water stress response, leaf drying, root phototropism, and sensitivity to glyphosate, nitrogen, potassium, magnesium, and UV-B light. Related genes in other species connect the family to root-to-shoot nitrate and potassium translocation, salt tolerance, and cadmium resistance.
