KC1 — Beta vulgaris subsp. vulgaris

Summary

BvKC1 (BVRB_3G066600) on sugar beet chromosome Bvchr3_un.sca001 encodes a voltage-sensitive potassium channel with outward rectifier potassium channel activity, potassium transporter activity, and ion transporter activity, and also carries annotations for ATPase inhibitor activity, calcium-dependent protein serine/threonine phosphatase activity, and SNARE functions. The gene is associated with regulation of membrane potential, monoatomic ion homeostasis, potassium transport, stomatal opening, and responses to drought, salinity, and basic pH. It is linked to traits including water use efficiency, transpiration rate, photosynthetic rate, yield, sucrose content, leaf necrosis tolerance, root hair and lateral root length, days to flowering, and vegetative growth time. Phenotypic associations include potassium translocation, stomatal opening, osmotic pressure regulation, reactive oxygen species response, and programmed cell death. Related genes in other species are linked to guard cell ion flux, stomatal closure, and seed germination.
