The exceptional toxicity of arsenate [As(V)] is derived from its close chemical similarity to phosphate (Pi), which allows the metalloid to be easily incorporated into plant cells through the high-affinity Pi transport system. In this study, we identified an As(V)-tolerant mutant of Arabidopsis thaliana named pht1;1-3, which harbors a semidominant allele coding for the high-affinity Pi transporter PHT1;1. pht1;1-3 displays a slow rate of As(V) uptake that ultimately enables the mutant to… CONTINUE READING
