HKT1 — Zea mays

Summary

ZmHKT1 (ZM00001EB071370) on maize chromosome 2 encodes a cation transporter HKT7 with transmembrane cation transporter, sodium transporter, and potassium transporter activities, and symporter activity. The gene is associated with regulation of sodium transporter activity, sodium and potassium ion membrane transport, potassium ion homeostasis, response to salt and osmotic stress, calcium signaling, ethylene anabolism, and meiotic drive. It localizes to the plasmalemma, Golgi membrane, ER membrane, and mitochondria. ZmHKT1 is associated with salt stress tolerance, sodium exclusion and accumulation, potassium retention, seed germination under salt stress, and traits including plant height, root length and volume, shoot dry weight, leaf relative water content, chlorophyll content, net photosynthetic rate, total soluble sugar content, and seed production. Related genes in other species are linked to sodium homeostasis, salt tolerance, and ion distribution.
