Relative expression levels of pathogenesis-related genes in N. benthamiana. N. benthamiana leaves were infiltrated with ptHR941 and an empty vector as control for RT-qPCR analysis. Leaves infiltrated with empty vector were used as control for relative quantification of gene expression. EF-1α was used as internal control. a-g Relative expression levels of a PR-1a vs control, b PR-5 vs control, c PDF1.2 vs control, d NPR1 vs control, e PAL vs control, f RBOHB vs control, and g ERF1 vs control. Significance was determined by t-test: *P < 0.05, **P < 0.01. Results are the mean values from three independent experiments. Vertical bars indicate SD
