Ion content in different tissues of transgenic hairy root-composite plant. a Cl− content, (b) NO3− content, (c) Cl−/NO3− ratio, (d) Na+ content, (e) K+ content, and (f) Na+/K+ ratio of transgenic hairy root-composite plants. Composite plants with hairy root transformed with vector, GmCLC1, and GsCLC-c2 were employed in this study. Results are presented as mean ± SD (n = 3). Data of different lines within the same tissue under control and NaCl treatment were analyzed together by one-way ANOVA followed by Duncan’s test. Letters indicate groups with statistically significant differences P ≤ 0.05
