Growth of wild type (WT) and transgenic plants (#25 and #27) under salt stress treatment.
(a–c) Phenotype (a), fresh weight (b) and electrolyte leakage (c) of WT and transgenic plants grown for 30 days on MS medium (Control, upper panel), MS medium added with 200 mM NaCl (middle panel) or MS medium added with 200 mM NaCl and 100 U/ml CAT (bottom panel). (d–g) Chlorophyll content (d), MDA content (e), H2O2 (f) and O2•− (g) in WT and transgenic plants under control and salt stress conditions. (h–i) Analysis of cell death (h) and DNA laddering profiles (i) of the leaves sampled from WT and transgenic plants grown on MS (control), MS + 200 mM NaCl or MS + 200 mM NaCl + 100 U/ml CAT. Error bars represent standard deviations for three replicates. Asterisks indicate significant difference between WT and transgenic lines under the same growth conditions (*P < 0.05, **P < 0.01, ***P < 0.001).
