Comparisons of salt stress-related physiological parameters in GsCLC-c2- and GmCLC1-transgenic soybean hairy root-composite seedlings. a Photo showing the hairy root-composite seedlings with or without NaCl treatment. b Fresh weight, (c) root vigor, (d) leaf area, (e) relative water content (RWC) of the 1st trifoliate, (f) root relative electrolyte leakage (REL), and (g) leaf REL were compared between vector-transformed-, GsCLC-c2- and GmCLC1-transgenic soybean hairy root-composite seedling with or without NaCl treatment. Results are presented as mean ± SD (n = 3). Data of different lines 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
