Figure 3.

Distribution of type III secretion system effectors (T3SEs) across the Pseudomonas syringae species complex. Black boxes indicate presence; grey boxes indicate possible truncation. It should be noted that avrB is listed as present by similarity, but is known not to translocate (Baltrus et al., 2011). T3SE names are given at the bottom—genes designated with the same letter are within the same family, numbers indicate subfamilies. The effector with similarity to PthG from Pantoea, indicated in bold, is putatively from outside the P. syringae species complex.
