Phylogenetic distribution of T6SS clusters in P. putida species. Maximum likelihood tree with 1000 bootstrap replicates were built with Mega 6 for the core component protein TssB. T6SS cluster nomenclature (Boyer et al., 2009; Barret et al., 2011) is used to show the major phylogenetic clusters. Three main groups are clearly distinguishable: group 1.2 (green), group 2 (red) and group 4B (blue). P. aeruginosa and A. tumefaciens T6SSs loci are included into the phylogenetic tree to illustrate all the subgroups: 1.1 (P. aeruginosa H2), 1.2 (P. putida K2-K3), 2 (P. putida W619), 3 (P. aeruginosa H1), 4A (P. aeruginosa H3), 4B (P. putida K1) and 5 (A. tumefacines).
