KC1 — Cucumis melo

Summary

MELO3C002718.2 (CmKC1) on melon chromosome 13 encodes a protein with domains including KHA_dom, KAT/AKT, ion transport, cNMP-binding, and RmlC-like jellyroll, and is annotated with outward rectifier potassium channel activity, potassium channel activity, ion transporter activity, and other molecular functions. The gene is associated with regulation of membrane potential, monoatomic ion homeostasis, regulation of K+ transport, upregulation of stomatal opening, and responses to basic pH, drought, salinity, and abscisic acid signaling. It is linked to traits including leaf necrosis tolerance, alkali soil sensitivity, water stress response, cadmium concentration, water use efficiency, transpiration rate, photosynthetic rate, yield, root hair length, lateral root length, days to flowering, vegetative growth time, and responses to aluminum and insect damage. Localisation evidence connects the product to the monoatomic ion channel complex, apical part of cell, pollen tube tip, cell plate, vesicles, and SNARE and CORVET complexes. Related genes in other species link the family to sodium, cadmium and lead tolerance, root gravitropism, and guard cell ion flux.
