KC1 — Solanum tuberosum

Summary

StKC1 (PGSC0003DMG400014505) on potato chromosome 8 encodes a voltage-sensitive potassium channel with outward rectifier potassium channel activity, potassium transporter activity, and ion transporter activity. It also shows 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, upregulation of stomatal opening, and downregulation of cellular defense response. StKC1 is linked to traits including yield, water use efficiency, transpiration rate, photosynthetic rate, leaf necrosis tolerance, water stress response, root mass density, root hair length, lateral root length, vegetative growth time, days to flowering, sucrose content, and responses to alkali soil, magnesium, potassium, nitrogen, cadmium, aluminum, gibberellic acid, ethylene, and jasmonic acid. It is also associated with potassium translocation, stomatal regulation, programmed cell death, osmotic pressure regulation, and reactive oxygen species response.
