KC1 — Capsicum annuum

Summary

CaKC1 (T459_02168) on pepper chromosome 1 encodes a potassium channel belonging to the KAT/AKT family, with outward rectifier potassium channel activity and ion transporter activity. The gene is associated with regulation of membrane potential, monoatomic ion homeostasis, and regulation of K+ transport, as well as upregulation of stomatal opening and hypotonic salinity response. It is linked to numerous traits including yield, water use efficiency, photosynthetic rate, transpiration rate, leaf number, root mass density, days to flowering, and vegetative growth time. Additional associations include water stress response, alkali soil sensitivity, magnesium sensitivity, potassium sensitivity, nitrogen sensitivity, cadmium concentration, aluminum response trait, and gibberellic acid sensitivity, along with leaf chlorosis, leaf necrosis tolerance, sucrose content, and insect damage response trait. The gene product localizes to the apical plasma membrane, pollen tube tip, vesicle, and cell plate, and is linked to programmed cell death, potassium homeostasis, and stomatal opening.
