| Abstract |
|
The mitochondrial genome of the Chinese big-headed turtle, Platysternon megacephalum, was obtained using polymerase chain reaction (PCR). The entire mtDNA sequence, the longest mitochondrial genome in turtles reported so far, is 19161 bp. This mitochondrial genome exhibits a novel gene order, which greatly differs from that of any other vertebrates. It is characterized by four distinctive features: 1) the translocation of a gene cluster including three tRNA genes (tRNA(His), tRNA(Ser), tRNA(Leu(CUN))) and ND5 gene, 2) two tRNA(Thr) pseudogenes, 3) a duplication of pseudo tRNA(Thr)/tRNA(Pro)/D-loop region and 4) 3 non-coding spacers. These unique identities represent a new mitogenomic gene order in vertebrates. The TDRL model was proposed to account for the generation of the gene order in P. megacephalum.
