Correction: Functional Analysis of the Na+,K+/H+ Antiporter PeNHX3 from the Tree Halophyte Populus euphratica in Yeast by Model-Guided Mutagenesis.

[This corrects the article DOI: 10.1371/journal.pone.0104147.].

There is an error in the title of the third subsection of the Results. The correct title is: PeNHX3 mediates Na+, K+ and Li+ transport in yeast.

There is an error in the title of the first subsection of the Discussion. The correct title is: PeNHX3 may function in salt stress and Li+ detoxification in P. euphratica.

There is an error in the title of the second to last subsection of the Discussion. The correct title is: Asn187 and Asp 188 forms an ND motif that is crucial for ion binding and ion translocation in PeNHX3.
