Analysis of H₂O₂ accumulation and oxidative enzymes under H₂O₂ stress condition. (A) Phenotype of nced3 and wild type leaves after 100 mM H₂O₂ treatment for 2 d. (B) DAB staining of H₂O₂ accumulation. Three independent replicates were performed. (C) SOD and CAT activities of nced3 and wild type three-leaf-stage seedlings under 100 mM H₂O₂ treatment for 24 h. Data shown are ± SD from three independent replicates. Asterisks indicate statistically significant differences (Student's t-test; ^*P < 0.05).
