Disrupting EPS and the putative LPS kinase WapQ alters Pst leaf adhesion and compromises plant infection. (A) Adhesion to tomato leaf surfaces. The graph denotes the number of cells adhered to leaf surfaces after 5 h. Means ±SD are presented, with values from two independent experiments and triplicates of each measurement represented with a different shape in the figure. (B) Bacterial load following spray infection at different days post-infection [D]. Wild-type (WT) Pst (black), ΔwapQ (red), ΔEPS (purple), and ΔEPS ΔwapQ (blue). Similar results were obtained in two biologically independent experiments and means ±SD are presented, with values from two independent experiments and triplicates of each measurement represented with a different shape in the figure. In each case, ∗P<0.05 determined by Student’s t-test.
