HKT1 — Cucumis melo

Summary

MELO3C017399.2 (symbol HKT1, preferred name CmHKT1) on melon chromosome 3 encodes a transmembrane cation transporter with sodium and potassium transporter activity, belonging to the TrkH/K-transport and cation transporter families. It is associated with sodium and potassium ion membrane transport, potassium ion homeostasis, osmotic response, and salinity response, and is localized to the plasma membrane, ER membrane, Golgi membrane, and mitochondria. The gene has been associated with salt tolerance, sodium accumulation and exclusion, potassium retention, seed germination under salt stress, root length, lateral root development, photosynthetic rate, drought tolerance, and seed production. Studies of related genes in other species link the family to sodium transport, recirculation, and homeostasis, potassium uptake, and fertility, and to fruit yield.
