KC1 — Capsicum annuum

Summary

CaKC1 (T459_14893) on pepper chromosome 5 encodes a protein with domains including KAT/AKT, ankyrin repeats, a cyclic nucleotide-binding domain, and an ion transport domain, and is annotated with outward rectifier potassium channel activity, potassium channel activity, and ion transporter activity. The gene is associated with regulation of membrane potential, potassium ion homeostasis and transport, stomatal opening, and responses to basic pH and hypotonic salinity. It is linked to traits including yield, water use efficiency, photosynthetic rate, transpiration rate, leaf necrosis tolerance, alkali soil sensitivity, cadmium concentration, and wheat powdery mildew disease response. Additional associations include potassium translocation, programmed cell death, osmotic pressure regulation, and reactive oxygen species response. Studies of related genes in other species connect the family to stomatal regulation, sodium and cadmium tolerance, seed germination, and gravitropism.
