The accumulation profiles of Na+ and K+ in the shoots of rice.
| NaCl Treatment | Lines | Na+ Content (mg/g, DW) | K+ Content (mg/g, DW) | Na+/K+ Ratio |
|---|---|---|---|---|

| OE-18 | 2.58 ± 0.17 | 17.51 ± 0.69 | 0.15 ± 0.01 | |
| OE-19 | 2.53 ± 0.26 | 17.77 ± 0.65 | 0.14 ± 0.02 | |
| 100 mM | WT | 14.42 ± 0.42 | 8.61 ± 0.61 | 1.68 ± 0.08 |

| OE-18 | 14.08 ± 0.80 | 10.28 ± 1.31 * | 1.38 ± 0.18 * | |
| OE-19 | 13.54 ± 0.95 | 9.92 ± 0.44 | 1.37 ± 0.12 ** | |
| 200 mM | WT | 27.90 ± 0.65 | 5.28 ± 0.72 | 5.35 ± 0.58 |
| OE-17 | 25.21 ± 1.27 ** | 6.70 ± 0.95 * | 3.80 ± 0.35 ** | |
| OE-18 | 25.62 ± 1.39 * | 7.80 ± 0.80 ** | 3.32 ± 0.48 ** | |
| OE-19 | 25.60 ± 0.89 * | 7.88 ± 0.54 ** | 3.26 ± 0.33 ** |
The error bars indicate the ±SD of five biological replicates. WT represents wild-type; OE-17, OE-18, and OE-19 represent the transgenic rice lines, respectively. DW: dried weight; * and ** indicate significant differences at the p < 0.05 level and p < 0.01 level, respectively (LSD-test).
