KC1 — Daucus carota subsp. sativus

Summary

DcKC1 (DCAR_014857) on carrot chromosome 4 encodes a protein belonging to the KAT/AKT family and containing ion transport, cNMP-binding and ankyrin repeat domains. The gene is associated with outward rectifier potassium channel activity, potassium channel activity, ion transporter activity, and regulation of membrane potential. It has been linked to numerous agronomically relevant traits including yield, water use efficiency, transpiration rate, photosynthetic rate, root mass density, lateral root length, leaf number, days to flowering, and responses to water stress, alkali soil, aluminum, cadmium, and powdery mildew. Associations also include potassium homeostasis, translocation and distribution, osmotic pressure regulation, stomatal opening, programmed cell death, reactive oxygen species response, and herbivory defense. The gene localizes to the plasma membrane, vesicle, cell plate, and pollen tube tip.
