KC1 — Daucus carota subsp. sativus

Summary

DcKC1 (DCAR_011386) on carrot chromosome 3 encodes a protein with domains including KHA_dom, KAT/AKT, and ion transport domains, and is annotated with outward rectifier potassium channel activity, ion transporter activity, ATPase inhibitor activity, and calcium-dependent protein serine/threonine phosphatase activity. The gene is associated with regulation of membrane potential, monoatomic ion homeostasis, regulation of potassium transport, and upregulation of stomatal opening. It is linked to traits including leaf necrosis tolerance, alkali soil sensitivity, water stress response, aluminum response, cadmium concentration, wheat powdery mildew disease response, yield trait, water use efficiency, transpiration rate, photosynthetic rate, root mass density, and days to flowering. Additional associations include potassium translocation, stomatal opening, reactive oxygen species response, programmed cell death, and mineral nutrient partitioning. The encoded protein localizes to monoatomic ion channel complexes, the apical plasma membrane, vesicles, and the cell plate.
