KC1 — Capsicum annuum

Summary

CaKC1 (T459_29178) on pepper chromosome 12 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 and potassium channel activity. The gene is associated with regulation of membrane potential, potassium ion homeostasis, stomatal opening, and responses to basic pH and hypotonic salinity. It is linked to traits including yield, water use efficiency, photosynthetic rate, transpiration rate, root and shoot growth, days to flowering, leaf necrosis tolerance, and responses to water stress, aluminum, cadmium, and powdery mildew. Additional associations include potassium translocation, xylem loading, stomatal regulation, and reactive oxygen species responses. Studies of related genes in other species connect the family to sodium and cadmium tolerance, root gravitropism, and seed germination.
