Effect of salt stress on contents of oxidants (A and B) and antioxidant enzymes (C–D) in wild-type and transgenic rice plants. (A and B) Plants were exposed to 200 mM NaCl for 2 days before determination of H₂O₂ (A) and malondialdehyde (MDA) (B). (C–E) were exposed to 200 mM NaCl for 24 hours and before determination of peroxidase (POD; C), superoxide dismutase (SOD; D), and catalase (CAT; E). Data are mean±SE of three replicates. Asterisks indicate statistically significant differences (P < 0.05) between wild-type (WT) and transgenic lines (OE and Ri).
