Dendrogram analysis of Pseudomonas syringae pv. syringae UMAF0158 and 25 selected strains of the P. syringae complex (see S1 Table) based on the presence of T3Es.
A matrix was created based on the presence/absence of T3E proteins (see supporting information S9 Table). Then, the corresponding distance matrix was inferred, and the R package APE was used to generate the tree (see Materials and Methods section). The scale shows the joining distance between each join point (strains) in the matrix. Some strains were labelled with the corresponding phylotype of pv. syringae [21, 22] and clade of phylogroup 2 of P. syringae complex .
