The mitochondrial genome of the Chinese giant salamander Andrias davidianus was isolated using the long-and-accurate polymerase chain reaction (LA PCR) method. The sequencing work adopted the shotgun strategy accompanying with seven internal primers to cover the gaps where overlapping clones were not available. The entire mtDNA sequence is 16,503 bp long, with a gene content of 13 protein-coding, two ribosomal RNA and 22 transfer RNA genes, and order identical to that observed in most other vertebrates except for an additional 318 bp non-coding sequence between tRNA-Thr and tRNA-Pro genes. In order to carry out molecular phylogenetic analyses, all 13 protein sequences deduced from whole mitochondrial genomes for eight vertebrate species (six amphibians, two lobe-finned fishes) were combined to a single data set. This data set was refined by the program Gblocks using a stringent parameter setting and then subjected to MP, ML and NJ analyses. Thus phylogenetic relationships among living amphibians were discussed.
