KC1 — Beta vulgaris subsp. vulgaris

Summary

BvKC1 (BVRB_2G043230) on sugar beet chromosome 2 encodes a protein with domains including KHA_dom, KAT/AKT, and is annotated with outward rectifier potassium channel activity, ion transporter activity, ATPase inhibitor activity, calcium-dependent protein serine/threonine phosphatase activity, and GAP binding. The gene is associated with regulation of membrane potential, monoatomic ion homeostasis, regulation of K+ transport, and upregulation of stomatal opening. It is linked to traits including yield, sucrose content, water use efficiency, photosynthetic rate, transpiration rate, root mass density, leaf number, days to flowering, vegetative growth time, and responses to water stress, alkali soil, aluminum, cadmium, and powdery mildew. Additional associations include potassium translocation, stomatal opening, reactive oxygen species response, and programmed cell death. Related genes in other species link the channel family to stomatal regulation, potassium accumulation, and stress tolerance.
