Cloning and Functional Analysis of <Emphasis Type="Italic">SaCLCc1</Emphasis>, a Gene Belonging to the Chloride Channel Family (<Emphasis Type="Italic">CLC</Emphasis>), from the Halophyte <Emphasis Type="Italic">Suaeda altissima</Emphasis> (L.) Pall.

One of the genes of the CLC (Chloride Channel) family, SaCLCc1, from the halophyte Suaeda altissima (L.) Pall. was cloned. To investigate the function of SaCLCc1, it was expressed in the S. cerevisiae deletion mutant Δgef1::LEU2 for the only gene of the CLC family in this organism. The growth of the transformed SaCLCc1-expressing mutant Δgef1 was restored when cells were grown in Fe²⁺-deficient YPEG medium, in minimal synthetic media SD and SR (pH 7.0), and in rich YPD medium containing Mn²⁺. The complementation of the Δgef1 mutant phenotype with the SaClCc1 gene indicates the involvement of the SaClCc1 protein in the transport of Cl^– ions.
