Supplementary Files (table,figure)

<b>Additional file 1: Table S1. </b>Amphibian species with mt gene duplication or loss in this study. (XLSX 12 kb) <b>Additional file 2: Figure S1.</b><b> </b>Phylogenetic tree of all amphibians studied using ML method based on the nucleotide dataset of 13 mt PCGs. The number of species sampled for each lineage is shown in brackets. We marked the branches of the species with mt gene rearrangements and the names of species only involved with PCGs rearrangements in dark red, and a pale red background was set on the branch of neobatrachians, the group with the most intensive rearrangements. (PDF 542 kb) <b>Additional file 3: Figure S2.</b> Mitogenomic rearrangement patterns of all amphibian species investigated. The numbers in first column indicated the occurrence frequencies of patterns(a number less than three is defined as a rare rearrangement in this study). (PDF 119 kb) <b>Additional file 4: Word S1. </b>Amplification scheme and primers sequences for sequencing four mitochondrial genomes in this study.(DOCX 14.2kb) <b>Additional file 5: Text S1. </b>Multiple sequence alignment file (fasta format, an input file for constructing phylogenetic trees) based on nucleic acid sequences of 13 protein-coding genes from 233 species mitogenomes. (TXT 2899kb) <b>Additional file 6: Table S2. </b>List of best models for performing phylogenetic tree based on BI method in this study. (XLSX 10 kb)<b></b><br>
