KC1 — Daucus carota subsp. sativus

Summary

DCAR_024742 (DcKC1) on carrot chromosome 7 encodes a protein with domains including KHA_dom, KAT/AKT, Ion_trans_dom, cNMP-bd_dom, Ankyrin_rpt, and others, and is annotated with outward rectifier potassium channel activity, potassium transporter activity, and additional molecular functions including 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, and downregulation of cellular defense response. It has been linked to numerous agronomically relevant traits including yield, water use efficiency, transpiration rate, photosynthetic rate, leaf necrosis tolerance, root mass density, lateral root length, root hair length, vegetative growth time, days to flowering, sucrose content, and responses to water stress, alkali soil, aluminum, cadmium, and powdery mildew. Localization evidence connects the product to the apical plasma membrane, pollen tube tip, cell plate, vesicle, and SNARE and CORVET complexes.
