Mt-genome rearrangements and fragmentation in booklice. A Comparison of number of gene boundaries (NGBs) between booklice with fragmented or non-fragmented mt-genomes. No significant difference was detected. The number above each error bar is sampling size. B A boxplot comparing the mt-genome rearrangements (NGBs count) across the species within the Liposcelis genus through pairwise comparisons. Each datapoint represents a comparison between the species considered and one of the other Liposcelis species. C The figure shows a comparison of mt-genome recombination (using NGBs as a proxy) between all species with fragmented and unfragmented mt-genomes. The datapoints are the same as the previous figure but they have been pooled together and no significant difference was detected. D Phylogenetic tree of the genus Liposcelis based on PCG123 dataset. The values in each node are posterior probability from MrBayes, bootstrap values based on IQtree and PhyML. Four branches with fragmented mt-genomes are labelled in red. All other trees based on three datasets (PCG123rRNA, PCG12, PCG12rRNA) are reported in Additional file 1: Fig. S2, and confirm the topology shown here
