KC1 — Asparagus officinalis

Summary

AoKC1 (KC1) on asparagus chromosome 6 encodes a protein with domains characteristic of potassium channels, including KHA, cNMP-binding, and ankyrin repeats, and is annotated with outward rectifier potassium channel activity, potassium transporter activity, and ion channel activity. The gene is associated with regulation of membrane potential, monoatomic ion homeostasis, stomatal opening, and responses to basic pH and hypotonic salinity. It has been linked to numerous agronomically relevant traits, including yield, water use efficiency, transpiration rate, leaf necrosis tolerance, root hair and lateral root length, days to flowering, and responses to water stress, alkali soil, and various nutrient sensitivities. Associations also include potassium translocation and reactive oxygen species response. Related genes in other species are linked to guard cell ion flux, seed germination, and stress tolerance.
