pap5-1 plants accumulate reduced H 2 O 2 in response to Pst DC3000 infection. A, Histochemical detection of H2O2 accumulation using DAB staining. Wild-type and pap5-1 leaves were excised following Pst DC3000 infection and stained with DAB for hydrogen peroxide. B, Quantification of H2O2 following Pst DC3000 infection. The bars represent mean and SD of H2O2 accumulation. Asterisks represent significant difference in H2O2 production compared to wild type (Student’s t-test; P < 0.05).
