Figure 3 From: A subgroup of plant aquaporins facilitate the bi-directional diffusion of As(OH)3 and Sb(OH)3across membranes Expression of Arabidopsis aquaporin homologs improves yeast growth in the presence of arsenate (As(V)). Δfps1 Δacr3 Δycf1 transformed with the empty vector pYES2.1 (control) or the indicated aquaporin homologs were spotted at an A600 of 0.01 on medium containing various concentrations of As(V) as indicated. Growth was recorded after 6 days at 30°C.Back to article page
