KC1 — Cucumis melo

Summary

MELO3C019454.2 (CmKC1) on melon chromosome 7 encodes a protein with domains including KHA_dom, KAT/AKT, and ion transport domains, and is annotated with outward rectifier potassium channel activity, potassium transporter activity, and ion transporter activity. It is associated with regulation of membrane potential, monoatomic ion homeostasis, regulation of K+ transport, and upregulation of stomatal opening. The gene is linked to numerous agronomic traits including yield, water use efficiency, transpiration rate, photosynthetic rate, leaf necrosis tolerance, alkali soil sensitivity, potassium sensitivity, cadmium concentration, iron concentration, sucrose content, root hair length, lateral root length, days to flowering, and vegetative growth time. It is also connected to potassium translocation, stomatal opening, osmotic pressure regulation, reactive oxygen species response, and programmed cell death. Studies of related genes in other species link the family to sodium tolerance, cadmium tolerance, lead uptake, and root gravitropism.
