Eight transmembrane segments in the Arabidopsis Na+ transporter, AtHKT1, have been proposed to be arranged around the axis of the pore. We report here that the addition of a GFP or a FLAG tag to the C terminus of AtHKT1 impairs the Na+ transport in Xenopus ooytes as detected by electrophysiological measurements.
