KC1 — Capsicum annuum

Summary

CaKC1 (T459_24156) on pepper chromosome 9 encodes a protein with outward rectifier potassium channel activity, potassium transporter activity, and ion transporter activity. It is associated with regulation of membrane potential, monoatomic ion homeostasis, cellular potassium ion homeostasis, and stomatal opening. The gene is linked to numerous agronomically important traits including yield, water use efficiency, transpiration rate, photosynthetic rate, leaf necrosis tolerance, alkali soil sensitivity, root hair length, lateral root length, days to flowering, and responses to water stress, cadmium, aluminum, and insect damage. It localizes to the pollen tube tip, apical plasma membrane, cell plate, and vesicle. Studies of related genes in other species link the family to sodium tolerance, cadmium tolerance, lead uptake, root gravitropism, and stomatal regulation.
