Modulation of AtZAT6 expression affects oxidative burst under mock and pathogen-infected conditions. A and B, Quantification of H₂O₂ content (A) and O₂•^– content (B) in plants under mock and pathogen-infected conditions. For the assays, 28-d-old plant leaves were infected with mock (10 mm MgCl₂), Pst DC3000 plus 10 mm MgCl₂, and Pst DC3000(avrRpt2) plus 10 mm MgCl₂ for designed times. Means ± sds of three independent experiments are shown in the results, and asterisks indicate the significant difference of P < 0.05 compared with the wild type (WT).
