KC1 — Daucus carota subsp. sativus

Summary

DCAR_027919 (DcKC1) on carrot chromosome 8 encodes a protein with domains including KAT/AKT, KHA_dom, and ion transport domains, and is annotated with outward rectifier potassium channel activity, ion transporter activity, ATPase inhibitor activity, calcium-dependent protein serine/threonine phosphatase activity, and GAP binding. The gene is associated with regulation of membrane potential, monoatomic ion homeostasis, regulation of K+ transport, upregulation of stomatal opening, response to basic pH, hypotonic salinity response, and response to nutrient. It localizes to the monoatomic ion channel complex, vesicle, cell plate, and pollen tube tip. DcKC1 is linked to traits including yield, water use efficiency, transpiration rate, photosynthetic rate, root mass density, leaf number, days to flowering, water stress response trait, aluminum response trait, cadmium concentration, and insect damage response trait. It is also associated with potassium translocation, stomatal opening, osmotic pressure regulation, and reactive oxygen species response. Related genes in other species link the family to stomatal regulation, seed germination, and jasmonic acid biosynthesis.
