KC1 — Daucus carota subsp. sativus

Summary

DcKC1 (DCAR_017845) on carrot chromosome 5 encodes a voltage-sensitive potassium channel with outward rectifier potassium channel activity, potassium transporter activity, and ion transporter activity, and also carries annotations for 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 potassium transport, upregulation of stomatal opening, and downregulation of cellular defense response, as well as responses to basic pH and hypotonic salinity. It has been linked to numerous agronomically relevant traits including yield, water use efficiency, transpiration rate, photosynthetic rate, leaf necrosis tolerance, alkali soil sensitivity, cadmium concentration, iron concentration, sucrose content, root hair length, lateral root length, root mass density, days to flowering, and vegetative growth time. The encoded protein localizes to the monoatomic ion channel complex, SNARE complex, pollen tube tip, apical plasma membrane, and cell plate.
