KC1 — Capsicum annuum

Summary

CaKC1 (T459_30434) on pepper chromosome 12 encodes a protein with domains including KHA, KAT/AKT, ion transport, cNMP-binding, ankyrin repeat, and RmlC-like jellyroll, and is annotated with outward rectifier potassium channel activity, potassium channel activity, ion transporter activity, and other molecular functions. The gene is associated with regulation of membrane potential, monoatomic ion homeostasis, regulation of K+ transport, upregulation of stomatal opening, downregulation of cellular defense response, response to basic pH, hypotonic salinity response, and response to nutrient. It is linked to traits including leaf necrosis tolerance, alkali soil sensitivity, water stress response, cadmium concentration, yield trait, water use efficiency, photosynthetic rate, transpiration rate, root hair length, lateral root length, days to flowering, vegetative growth time, and responses to aluminum, insect damage, and other factors. Additional associations include potassium translocation, programmed cell death, osmotic pressure regulation, and reactive oxygen species response. Related genes in other species link the family to sodium and cadmium tolerance, lead uptake, root gravitropism, and stomatal regulation.
