KC1 — Daucus carota subsp. sativus

Summary

DcKC1 (DCAR_022886) on carrot chromosome 6 encodes a protein with voltage-sensitive potassium channel, outward rectifier potassium channel activity, potassium transporter activity, ion transporter activity, ion channel activity, ATPase inhibitor activity, and protein membrane adaptor activity, among other annotated molecular functions. The protein contains KAT/AKT, ion transport, cNMP-binding, and ankyrin repeat domains. DcKC1 is associated with regulation of membrane potential, potassium ion homeostasis and transport, stomatal opening, and responses to pH, salinity, and nutrients. It is linked to traits including yield, water use efficiency, photosynthetic rate, transpiration rate, root mass density, leaf number, days to flowering, vegetative growth time, and responses to water stress, aluminum, cadmium, and powdery mildew. Additional associations include potassium translocation, stomatal opening, programmed cell death, reactive oxygen species response, and herbivory defense.
