Distribution of inversions. a Different color of regions in the map correspond to the number of strains included in this analysis. Pie chart along each region shows the distribution of the inversions in strains of that region (Additional file 12: Table S7). b R1-R23 and R24-R41 were identified as shared and strain-specific inversions, respectively. Among the shared inversions, R17-R23 were region-specific
