Table 4 The number of strains of Pseudomonas syringae in phylogroup 2 and for all phylogroups considered together according to their host range extent and capacity to swarm on semi-solid nutrient medium. In both cases, there is a significant interaction of host range extent and swarming (Fisher’s exact test, P < 0.01). There were not sufficient strains to test the interaction of swarming and host range for phylogroups other than PG02
