KC1 — Asparagus officinalis

Summary

AoKC1 (A4U43_C09F4170) on asparagus chromosome 9 encodes a protein belonging to the KAT/AKT family, with outward rectifier potassium channel activity, ion transporter activity, and additional annotated functions including ATPase inhibitor activity, calcium-dependent protein serine/threonine phosphatase activity, and GAP binding. The gene is associated with regulation of membrane potential, monoatomic ion homeostasis, regulation of K+ transport, upregulation of stomatal opening, response to basic pH, and hypotonic salinity response. It has been linked to numerous agronomically relevant traits including yield, water use efficiency, transpiration rate, photosynthetic rate, leaf necrosis tolerance, root hair length, lateral root length, days to flowering, vegetative growth time, and responses to water stress, aluminum, cadmium, and powdery mildew. Additional associations include potassium translocation, stomatal opening, reactive oxygen species response, and programmed cell death.
