A comparison of Na+ influx into excised roots from seedlings of control plants and those with defined mutations
The controls were Columbia (for akt1), Ws (for skor-1 and scr-2), and Columbia gl1 (for sos3-1, hkt1-3, and sos3 hkt1). Seedlings were 12 d old, except for scr-2 seedlings, which were 19 d old, to allow the mutant plants to reach a comparable size with control plants. Values represent mean ± se (n = 6). FM, Fresh mass.
| Mutant Name | Na+ Influx

|---|---|---|
| Control | Mutant | |
| μmol g−1 FM min−1 | ||
| akt1 | 1.95 ± 0.09 | 2.14 ± 0.28 |
| skor-1 | 1.82 ± 0.10 | 1.50 ± 0.14 |
| sos3-1 | 2.48 ± 0.17 | 2.40 ± 0.13 |
| hkt1-3 | 2.48 ± 0.17 | 2.47 ± 0.12 |
| sos3-1 hkt1-3 | 2.48 ± 0.17 | 2.38 ± 0.10 |
| scr-2 | 1.82 ± 0.10 | 2.10 ± 0.09a |
a When statistically significantly different to the respective controls, P < 0.05.
