Growth responses of wild-type (WT) and aha2 mutant plants to lithium and cesium. A, Root growth response to LiCl. Seedlings were germinated for 3 d on control medium (one-half-strength MS, 1% Suc, pH 5.7) and further grown on control medium or medium supplemented with LiCl at the concentrations indicated on the x axis. The asterisk indicates statistical significance between the wild type and aha2 mutants (P < 0.0001). B, Images of seedling growth on the medium supplied with LiCl. Seedlings were germinated for 3 d on control medium (one-half-strength MS, 1% Suc, pH 5.7) and further grown on medium supplemented with 20 mm LiCl. C, Root growth responses to CsCl. The asterisk indicates statistical significance between the wild type and aha2 mutants (P < 0.0001). D, Images of seedling growth on medium supplied with CsCl. E, Effect of potassium on lithium-induced root growth inhibition. F, Effect of potassium on cesium-induced root growth inhibition.
