Phylogenetic tree of 134 strains of Pseudomonas syringae from eight phylogroups and of P. corrugata for which virulence was evaluated on 16 to 22 plant species. The extent of the host range of each strain is indicated in the outer colored circle (virulent on > 75% of plant species tested: black; > 50% to 75%: red; > 25% to 50%: pink; > 10% to 25%: dark green; > 0 to 10%: light green; 0: white). Strains were considered to be virulent on a plant species if they caused symptoms on at least half of the replicate plants in each test. The neighbor-joining phylogenetic tree was constructed based on partial sequences of the citrate synthase housekeeping gene as previously described (Berge et al. 2014)
