| Abstract |
|
We first determined two complete mitochondrial genomes of Kinosternidae (Kinosternon leucostomum, 16 559bp and Sternotherus carinatus, 16 554bp) by primer walking and long-PCR technique, which were deposited in the GenBank database under the accession number FJ915117 and HQ114563 respectively. In the two sequences, we identified three distinctive features: (1) a 31bp nucleotides intergenic regions located between the COX1 and tRNASer (UCN) genes, but found so far generally overlapped by 9bp or 5bp in other turtle families; (2) a 10bp spacer between tRNACys and tRNATyr, while most other turtle families had no spacers; (3) a single nucleotide insertion in the ND4 gene of S. carinatus, which was rarely observed in other turtles. The phylogenetic analyses based on the 12 mtDNA protein genes indicated that the ML and BI trees all showed K. leucostomum and S. carinatus assembled together to form a clade of the Kinosternidae which was sister group to the Chelydridae; and the assemblage of Kinosternidae + Chelydridae had a sister-taxon relationship to the Cheloniidae + Testudinoidea clade. Although the Asian "box turtle" and the kinosternids all had the kinetic plastron with the hinge, it was found that the Asian "box turtle" was not close to the Kinosternidae, indicating that the hinge structure might not be derived from one common ancestor.
