KC1 — Sorghum bicolor

Summary

SbKC1, encoded by the sorghum gene SORBI_3006G093400 on chromosome 6, is a protein belonging to the KAT/AKT family, with outward rectifier potassium channel activity and ion transporter activity. It is associated with regulation of membrane potential, potassium ion transport and homeostasis, stomatal opening, and responses to basic pH and hypotonic salinity. The gene has been linked to numerous agronomically relevant traits, including yield, leaf necrosis tolerance, water stress response, transpiration rate, root mass density, nitrogen sensitivity, and cadmium concentration. It is also connected to alkali soil sensitivity, magnesium sensitivity, and wheat powdery mildew disease response. Related genes in other species link the family to potassium translocation, drought stress tolerance, osmotic stress tolerance, and grain potassium content.
