Figure 1

Yeast expressing specific Arabidopsis aquaporin homologs display sensitivity to arsenite (As(III)) and antimonite (Sb(III)). Δfps1 (background W303-1A) cells were transformed with the empty vector pYES2.1 (control) or aquaporin homologs rAQP9, ScFPSI, AtNIP1;1, Atnip1;1Δ2–44, AtNIP2;1, Atnip2;1Δ2–37, AtNIP5;1, Atnip5;1Δ2–67, AtNIP6;1, Atnip6;1Δ2–69, AtNIP7;1 or Atnip7;1Δ2–35 and spotted at an A600 of 0.01 on medium containing various concentrations of (A) As(III) or (B) Sb(III) as indicated. Growth was recorded after 5 days at 30°C. All data were duplicated in at least two independent experiments with consistent results.
