KC1 — Cucumis melo

Summary

MELO3C022820.2 (CmKC1) on melon chromosome 10 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 K+ transport, and upregulation of stomatal opening. It is linked to traits including leaf necrosis tolerance, alkali soil sensitivity, magnesium sensitivity, potassium sensitivity, water stress response, nitrogen sensitivity, cadmium concentration, yield, water use efficiency, photosynthetic rate, transpiration rate, light intensity response, and insect damage response. Additional associations include potassium translocation, programmed cell death, osmotic pressure regulation, reactive oxygen species response, and stomatal opening. Studies of related genes in other species link the family to sodium tolerance, cadmium tolerance, root gravitropism, and stomatal regulation.
