KC1 — Sorghum bicolor

Summary

SbKC1, encoded by SORBI_3002G049700 on sorghum chromosome 2, is a voltage-sensitive potassium channel with outward rectifier potassium channel activity, ion transporter activity, and additional annotated functions including ATPase inhibitor activity, calcium-dependent protein serine/threonine phosphatase activity, and SNARE-related roles. The gene is associated with regulation of membrane potential, upregulation of stomatal opening, potassium ion transport and homeostasis, response to basic pH, hypotonic salinity response, and cell plate formation. It is linked to leaf necrosis tolerance, water stress response, transpiration rate, stomatal complex closure time, days to flowering, sucrose content, nitrogen sensitivity, aluminum response, cadmium concentration, and insect damage response. Additional associations include potassium translocation, osmotic pressure regulation, reactive oxygen species response, and herbivory defense.
