Additional file 2 of Rapid evolution of mitochondrion-related genes in haplodiploid arthropods

Additional file 2: Figures S1–S4. Fig. S1 Terminal branch evolutionary ratesof different gene categories among arthropod groups. Asterisks indicate significant differences among hymenopterans, other non-Hymenoptera haplodiploid species, or diploid species. Fig. S2 Correlation between divergence time and terminal branch evolutionary ratesbased on Spearman’s rank correlation. Spearman’s rank correlation coefficient is estimated based on all species from hymenopterans, other non-Hymenoptera haplodiploid species, or diploid species. Fig. S3 Root-to-tip evolutionary rate of different gene categories among all species, hymenopterans, other haplodiploid species, and diploid species. Significance was denoted based on letters. Letters on top of the violin plots denote significant differences based on the Kruskal-Wallis test and multiple comparison tests after Kruskal-Wallis. Letters were ordered alphabetically based on the median of the distributions from the highest to the lowest. Fig. S4 Terminal branch evolutionary rate of different gene categories among hymenopterans with subsampling strategy. In each subsampling, one hymenopteran with the rest of the arthropods to keep the divergence time consistent among subsamples
