Influence of ar/R selectivity filter substitution of OsLsi1 on the transport activity for silicic acid (A), arsenite (B), boric acid (C), and water (D). Transport activity was determined for the water-injected negative control (H2O), oocytes expressing native OsLsi1 (GSGR original), or mutated proteins G88A (ASGR), S207I (GIGR), and G88A-S207I (AIGR). Data are means ±SD (n=3) for (A) and (B), (n=5–8) for (C) and (D). Different letters above the columns indicate statistically significant differences at P <0.05 by Tukey's test.
