KC1 — Solanum tuberosum

Summary

StKC1 (PGSC0003DMG400009648) on potato chromosome 8 encodes a voltage-sensitive potassium channel belonging to the KAT/AKT family, with outward rectifier potassium channel activity and ion transporter activity. It is associated with regulation of membrane potential, monoatomic ion homeostasis, and potassium transport, as well as stomatal opening, wound healing, and responses to drought, salinity, and basic pH. The gene is linked to traits including water use efficiency, transpiration rate, photosynthetic rate, yield, leaf necrosis tolerance, root hair and lateral root length, days to flowering, and responses to aluminum, cadmium, and insect damage. It localizes to the apical plasma membrane, pollen tube tip, vesicle, and cell plate, and is connected to ABA-mediated signaling and drought response pathways. Studies of related genes in other species link the family to stomatal regulation, potassium accumulation, and stress tolerance.
