KC1 — Capsicum annuum

Summary

CaKC1 (T459_32400) on pepper chromosome PGAv.1.6.scaffold798 encodes a potassium channel protein belonging to the KAT/AKT family, 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 basic pH and hypotonic salinity. CaKC1 has been linked to numerous agronomic traits including yield, water use efficiency, photosynthetic rate, transpiration rate, leaf necrosis tolerance, root hair length, lateral root length, days to flowering, vegetative growth time, and responses to water stress, aluminum, cadmium, and insect damage. It is also associated with potassium translocation, stomatal opening, programmed cell death, and reactive oxygen species response. Related genes in other species are linked to sodium and cadmium tolerance, root gravitropism, and seed germination.
