KC1 — Beta vulgaris subsp. vulgaris

Summary

BvKC1 (BVRB_2G047040) on sugar beet chromosome Bvchr2_un.sca010 encodes a protein with voltage-sensitive potassium channel, outward rectifier potassium channel activity, potassium transporter activity, and ion transporter activity, also annotated with ATPase inhibitor, calcium-dependent protein serine/threonine phosphatase, and GAP binding activities. The protein contains KHA, cNMP-binding, and ankyrin repeat domains. BvKC1 is associated with regulation of membrane potential, potassium transport, stomatal opening, hypotonic salinity response, and wound healing. It is linked to numerous agronomic traits including yield, sucrose content, water use efficiency, photosynthetic rate, transpiration rate, root mass density, lateral root length, root hair length, days to flowering, leaf number, and vegetative growth time. Associations also include potassium translocation, osmotic pressure regulation, reactive oxygen species response, and mineral nutrient partitioning.
