Fig. S1 Neighbor-joining tree constructed on the basis of sequences of the housekeeping gene fragment cts for 70 environmental Pto relatives and 23 clonal P. syringae crop pathogens.

Fig. S2 (a) Neighbor-joining tree based on the concatenated set of the nine gene fragments also used to build the phylogenetic tree shown in Fig. 2; (b) Bayesian consensus trees based on the individual nine gene fragments treating gene fragments as partitions with their own evolutionary models.

Fig. S3 Disease symptoms caused by environmental strains on Arabidopsis thaliana ecotype ‘Columbia’, cauliflower, celery and snapdragon, compared with a crop pathogen of each plant species and the Pto strain K40.
