KC1 — Beta vulgaris subsp. vulgaris

Summary

BvKC1 (BVRB_8G195260) on sugar beet chromosome 8 encodes a protein with domains including an ion transport domain, and ankyrin repeats, and belongs to the KAT/AKT family. The gene product exhibits outward rectifier potassium channel activity, potassium transporter activity, and ion transporter activity. BvKC1 is associated with regulation of membrane potential, monoatomic ion homeostasis, potassium transport, and stomatal opening. It is linked to traits including yield, sucrose content, water use efficiency, transpiration rate, photosynthetic rate, leaf necrosis tolerance, alkali soil sensitivity, cadmium concentration, and root hair length. The gene is also associated with potassium translocation, stomatal opening, reactive oxygen species response, and osmotic pressure regulation. Studies of related genes in other species link the family to guard cell ion flux, stomatal regulation, and potassium accumulation.
