KC1 — Asparagus officinalis

Summary

A4U43_C04F27160, designated AoKC1 on asparagus chromosome 4, encodes a protein with domains including KAT/AKT, K_chnl_volt-dep_EAG/ELK/ERG, and Ion_trans_dom, and is annotated with outward rectifier potassium channel activity, potassium channel activity, and ion transporter activity. The gene is associated with regulation of membrane potential, monoatomic ion homeostasis, and regulation of K+ transport. AoKC1 is linked to traits including leaf necrosis tolerance, alkali soil sensitivity, magnesium sensitivity, potassium sensitivity, water stress response trait, nitrogen sensitivity, cadmium concentration, inflorescence development trait, wheat powdery mildew disease response, iron concentration, aluminum response trait, leaf chlorosis, sucrose content, leaf number, gibberellic acid sensitivity, yield trait, insect damage response trait, cotyledon morphology trait, vegetative growth time, root hair length, lateral root length, transpiration rate, light intensity response, days to flowering trait, root mass density, water use efficiency, ethylene sensitivity, jasmonic acid content, plant stress response trait, and photosynthetic rate. The encoded protein localizes to the monoatomic ion channel complex, apical part of cell, pollen tube tip, nuclear membrane, apical plasma membrane, vesicle, and cell plate. Related genes in other species link the family to potassium homeostasis, stomatal regulation, and seed production.
