BUSCO scores of de novo assemblies. Stacked barplots showing the proportions of complete, complete and duplicated, fragmented, and missing BUSCO genes of the order Rickettsiales identified in each of the assembled genomes. Historic samples are shown above the dashed lines and 9 newly sequenced specimens are shown below the line. The color of the label names indicates that they are either of type wMel (blue) or wMelCS (red).
