Transcriptome changes associated with Pto/Prf-mediated ETI and flagellin-activated PTI. (A) RG-PtoR tomato plants were vacuum-infiltrated with different DC3000 mutants (Table 1). Leaf photographs were taken 4 days later. (B) Total number of genes differentially expressed during ETI (calculated as the ratio between the expression in DC3000 ΔfliC and DC3000 ΔavrPto ΔavrPtoB ΔfliC) or PTI (calculated as the ratio between DC3000 ΔavrPto ΔavrPtoB and the triple mutant) at 6 hai. A ≥2-fold difference and P <0.05 were used as cutoff. The number of genes in each category is shown.
