Growth of <i>Pst hrcC</i>^<i>-</i> (A) and <i>Psp</i> 1448a (B) in Col-0, <i>tga1-1 tga4-1, npr1-1 and tga1-1 tga4-1 npr1-1</i> plants.

<p>Four-week old leaves were syringe-infiltrated with a bacterial suspension of <i>Pst </i><i>hrcC</i>^<i>-</i> at 10⁵ colony forming units (cfu) ml^-1 or <i>Psp</i> 1448a at 10⁶ cfu ml^-1. The error bars represent the standard deviation of six replicates, each containing 8 leaf discs from one plant. An ANOVA of the log-transformed data was performed at α = 0.05; treatments with common letters over bars are not significantly different from each other. Post-hoc tests are presented in Table S2. Each experiment was repeated twice with similar results.
