Regions of sampling the Yersinia strains used in this study plotted using the program ArcMap.
The administrative boundaries on the map were obtained from the GADM database of Global Administrative Areas (version 2.8) accessible at https://gadm.org.

Phylogenetic tree designed by the progressiveMauve alignment of chromosomal sequences of several selected Yersinia isolates and reference genomes.
Fig 3.
The dendrogram of clusters of Yersinia isolates based on the 0/1 matrix of successful/unsuccessful BLASTN searches for sequences of polymorphic regions across the whole genome sequences of the isolates.
Isolation sources, regions, and landscapes are marked as explained in the figure legend. The results of the BLASTN search for six polymorphic regions within protein-coding genes of the reference strain Y. pseudotuberculosis IP 32953 are represented by ‘X’ symbols, indicating a negative search result, meaning that the region is either missing or modified in the subject genome.
