Figure 7. Effect of drought and salt stress on contents of H₂O₂ and malondialdehyde.

H₂O₂ contents in wild-type and transgenic plants in control and treatment with drought and salt stress (panel A). Malondialdehyde contents in wild-type and transgenic plants in control and treatment with drought and salt stress (panel B). Four-week-old seedlings withheld water or irrigated with 200 mM NaCl for 6 days were used in the experiments. Data are means ± SE of three biological replicates. Asterisks represent statistically significant differences between wild-type and transgenic lines. * P≤0.05, ** P≤0.01.
