Shoot accumulation of Cl^– was increased in the NPF2.4 overexpression lines, while NO₃⁻ content remained unaffected. A, Cl^– concentrations in the shoot of NPF2.4 overexpression lines and null segregants after high salt treatment (75 mm NaCl). B, NO₃^– concentrations in the shoot of NPF2.4 overexpression lines and null segregants after high salt treatment. C, Cl^– concentrations in the shoot of NPF2.4 overexpression lines and null segregants after low salt treatment (2 mm NaCl). D, NO₃^– concentrations in the shoot of NPF2.4 overexpression lines and null segregants after low salt treatment. Error bars represent mean ± se; n = 4. Significance is indicated by the asterisks (single-factor ANOVA and Tukey test, * P ≤ 0.05).
