Figure 2

Pan- and core-genome plot (A) and flower plot diagram (B) of 17 Leu. mesenteroides strains. An ordered list of the 17 strains was randomly generated and 20 sets of the randomly ordered strains were subjected to pan- and core-genome analysis. The average number of core- and pan-genome sizes were plotted with standard deviations. The pan-genome represents the total genes of genomes in a subset sampled and the core-genome represents the genes shared by all genomes in the same subset. The flower plot diagram represents gene numbers in the core-genome (in the center) and unique-genome (in the petals) of Leu. mesenteroides pan-genome, and in the genome of each Leu. mesenteroides strain (in the parentheses). The type strains of Leu. mesenteroides subspecies are highlighted in bold.
