Abstract Most plants do not tolerate highly saline environments; the development of salt stress tolerance is crucial for improving crop yield. An efficient way of finding genes involved in salt tolerance is to study and use data from halophytes. In this study, we used the Mesembryanthemum crystallinum (ice plant) expression data-set and selected for further study the gene McHKT2, which encodes for the Arabidopsis sodium transporter ortholog AtHKT1. In comparison with the HKT1 amino acid sequences from other plants, McHKT2 has several unique features. It seems to be localized to the plasma membrane, and its overexpression confers strong salt tolerance in Arabidopsis thaliana. Our results indicate that McHKT2 is a suitable candidate protein that can induce salt tolerance in non-halophytes. Like McHKT2, using transcriptome data-sets from halophytes such as ice plant give us an efficiency way to obtain new gene resources that might involve in plant salt tolerance.
