The oxidative burst assay in WT and SsbXoc transgenic N. benthamiana plants inoculated with Hpa1 and Pst DC3000. WT and transgenic plants were injected with Hpa1 protein (10 μg ml-1) and Pst DC3000 pathogen (OD = 0.01), and at 6 hpi, treated leaves were collected. (A) Visualization of H2O2 accumulation by DAB staining in leaves inoculated with Hpa1 and Pst DC3000. (B) Evaluation of H2O2 levels in leaves. Upper panel shows H2O2 levels in WT and transgenic lines inoculated with empty vector preparation (EVP; negative control) and Hpa1; Lower panel shows H2O2 levels in WT and transgenic lines inoculated with 10 mM MgCl2 (negative control) and Pst DC3000. (C) Phenotypes of WT and transgenic lines inoculated with Hpa1 and Pst DC3000 after 24 h. Inoculation sites are indicated with open circles. Error bars represent SD, and values with different letters are significant at P < 0.05.
