KC1 — Capsicum annuum

Summary

CaKC1 (T459_33060) from pepper (Capsicum annuum) encodes a protein with domains characteristic of voltage-gated potassium channels, including KHA, KAT/AKT, and ion transport domains, and is annotated with outward rectifier potassium channel activity and ion transporter activity. The gene is associated with regulation of membrane potential, potassium ion homeostasis, stomatal opening, and responses to drought, salinity, and abscisic acid signaling. It has been linked to numerous agronomically relevant traits, including yield, water use efficiency, photosynthetic rate, transpiration rate, leaf necrosis tolerance, root hair length, lateral root length, days to flowering, and responses to water stress, alkali soil, and various nutrient sensitivities. Localization evidence connects the product to the plasma membrane, pollen tube tip, vesicle, and cell plate. Studies of related genes in other species link the family to stomatal regulation, ion transport, and stress tolerance.
