【 摘 要 】

The Black Bridged Leaf Turtle, Cyclemys atripons (Testudines; Cryptodira; Geoemydidae), is a poorly known species within the genus Cyclemys. We determined the complete nucleotide sequence of the Cyclemys atripons mitochondrial genome (mtDNA) and found it to be 16,500 base pairs (bp) in length, with the genome organization, gene order and base composition being identical to that of the typical vertebrate. However, unlike for most turtle mtDNA so far reported, an extra base was not found in the NADH3 gene. The C. atripons control region of mtDNA was 981 bp long. Comparisons with three other geoemydids showed that the C. atripons control region contained a highly variable region at the 3' end composed of AT enriched tandem repeats containing a fifteen-unit 5'-A (AT)3-3' variable number of tandem repeats (VNTRs).
