摘要： Simple Summary Duplicated control regions have been reported several times in the tree frog family Rhacophoridae, and previous studies have mostly relied on sequence analysis to reconstruct their evolution. This is the first study to employ a phylogenetic method to demonstrate the existence of concerted and parallel evolution succinctly and intuitively in the duplicated control regions of the family Rhacophoridae. Phylogenetic relationships were also used to illustrate the parallel evolution of ATP8 loss of function in the genus Polypedates. In general, this study elucidated the evolutionary patterns and pathways of mitochondrial gene rearrangement of the family Rhacophoridae from a phylogenetic perspective, which aids in understanding the evolutionary history of this fascinating tree frog taxon from a molecular evolution standpoint. New developments in sequencing technology and nucleotide analysis have allowed us to make great advances in reconstructing anuran phylogeny. As a clade of representative amphibians that have radiated from aquatic to arboreal habitats, our understanding of the systematic status and molecular biology of rhacophorid tree frogs is still limited. We determined two new mitogenomes for the genus Polypedates (Rhacophoridae): P. impresus and P. mutus. We conducted comparative and phylogenetic analyses using our data and seven other rhacophorid mitogenomes. The mitogenomes of the genera Polypedates, Buergeria, and Zhangixalus were almost identical, except that the ATP8 gene in Polypedates had become a non-coding region; Buergeria maintained the legacy "LTPF" tRNA gene cluster compared to the novel "TLPF" order in the other two genera; and B. buergeri and Z. dennysi had no control region (CR) duplication. The resulting phylogenetic relationship supporting the above gene rearrangement pathway suggested parallel evolution of ATP8 gene loss of function (LoF) in Polypedates and CR duplication with concerted evolution of paralogous CRs in rhacophorids. Finally, conflicting topologies in the phylograms of 185 species reflected the advantages of phylogenetic analyses using multiple loci.
