KC1 — Solanum tuberosum

Summary

StKC1 (KC1) on potato chromosome 9 encodes a potassium channel NKT1 protein belonging to the KAT/AKT family with a KHA domain, annotated with outward rectifier potassium channel activity, ion transporter activity, and additional molecular functions including ATPase inhibitor activity and calcium-dependent protein serine/threonine phosphatase activity. The gene is associated with regulation of membrane potential, monoatomic ion homeostasis, potassium transport regulation, stomatal opening, and wound healing. It localizes to the ion channel complex, apical plasma membrane, pollen tube tip, and vesicle. StKC1 is associated with leaf necrosis tolerance, alkali soil sensitivity, magnesium sensitivity, potassium sensitivity, water stress response, nitrogen sensitivity, cadmium concentration, inflorescence development, wheat powdery mildew disease response, iron concentration, aluminum response, leaf chlorosis, sucrose content, leaf number, gibberellic acid sensitivity, yield, insect damage response, cotyledon morphology, vegetative growth time, root hair length, lateral root length, transpiration rate, light intensity response, days to flowering, root mass density, water use efficiency, ethylene sensitivity, jasmonic acid content, plant stress response, and photosynthetic rate.
