Influence of ar/R selectivity filter substitution of AtNIP5;1 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), native AtNIP5;1 (AIGR original), A117G (GIGR), I236S (ASGR), and A117G-I236S (GSGR). Data are means ±SD (n=3) for (A) and (B), (n=5–6) for (C) and (D). Different letters above the columns indicate statistically significant differences at P <0.05 by Tukey's test.
