FIG. 2.

Structure analysis of Y. pseudotuberculosis isolates. The three subpopulations are color coded green, red, and blue for subpopulations I, II, and III, respectively. Each isolate has been allocated to a subpopulation. The isolates were identified by strain name, with the ST in parentheses, on the left. Mosaic colors for an isolate indicate mixed population origins from the respective populations with matching colors. The y axis represents the percentage of population assignment, i.e., the proportions of ancestry from the 3 subpopulations as color coded.
