Figure. S2. 3D view of the genome features of the 23 Xac strains. The red triangles denote XacA* strains, the pink circles denote XacAw strains and the yellow diamond denote XacA strains.

Figure S3. Depletion curves of core-genome (left) and accumulation curves of pan-genome (right) of the 23 Xac strains. The fitted curves (red line) were added by using get_homologues based on model proposed by Tettelin in 2005 (Pubmed=16172379)
Figure S4. Results of the ClonalFrame analysis on the basis of un-gapped sequences of the longest 9 aligned blocks of 23 Xac genomes generated by progressiveMAUVE. The inferred clonal genealogy was shown on the left and the distribution of the recombination (red) and mutation (green) events estimated by ClonalFrame on the corresponding branches were shown on right. The distribution of the 9 blocks were indicated according to the start and end position on XacA306 chromosome. All possible events revealed by ClonalFrame were shown, and the relationship between event panels and their corresponding nodes were indicated with dash lines. The recombination events (red in the event panels) only occurred in XacA node and Aw & A* node (red dash lines).
