Growth of Th2CysPrx transgenic lines and WT tobacco under NaCl stress. a The distribution chart of the WT, Line7 and 11 in the plates. b, c Seed germination of Th2CysPrx-transformed lines and WT plants under normal conditions (1/2 MS) and salt (125 mM NaCl) stress for 10 d. d Seed germination rates assay. e Chlorophyll contents assay. f The growth phenotype of Th2CysPrx transformed and WT plants. Analysis of fresh weight (g) and root length (h). Control: under normal conditions. All experiments were repeated three times. Data are the mean ± SD of three independent experiments. Asterisks (*, P < 0.05) indicate significant difference compared with WT plants
