KC1 — Beta vulgaris subsp. vulgaris

Summary

BvKC1 (BVRB_6G143700) on sugar beet chromosome 6 encodes 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, monoatomic ion homeostasis, regulation of K+ transport, upregulation of stomatal opening, and responses to basic pH, hypotonic salinity, and wounding. It is linked to numerous agronomically important traits including yield, sucrose content, water use efficiency, transpiration rate, photosynthetic rate, leaf number, root mass density, days to flowering, and vegetative growth time. Associations also include leaf necrosis tolerance, alkali soil sensitivity, cadmium concentration, aluminum response, and wheat powdery mildew disease response. The encoded protein localizes to ion channel complexes, the plasma membrane, vesicles, and the cell plate.
