| 中文摘要 | The mitochondrial genome complete sequence of Achalinus meiguensis was reported for the first time in the present study. The complete mitochondrial genome of A. meiguensis is 17239 bp in length and contains 13 protein-coding genes, 22 tRNA, 2 rRNA, and 2 non-coding regions (Control regions). On the basis of comparison with the other complete mitochondrial sequences reported, we explored the characteristic of structure and evolution. For example, duplication control regions independently occurred in the evolutionary history of reptiles; the pseudo-tRNA of snakes occurred in the Caenophidia; snake is shorter than other vertebrates in the length of tRNA because of the truncations of T psi C arm (less than 5 bp) and "DHU" arm. The phylogenic analysis by MP and BI analysis showed that the phylogenetic position of A. meiguensis was placed in Caenophidia as a sister group to other advanced snakes with the exclusion of Acrochordus granulatus which was rooted in the Caenophidia. Therefore we suggested that the subfamily Xenodermatinae, which contains A. meiguensis, should be raised to a family rank or higher rank. At the same time, based on the phylogenic statistic test, the tree of Bayesian was used for estimating the divergence time. The results showed that the divergence time between Henophidia and Caenophidia was 109.50 Mya; 106.18 Mya for divergence between Acrochordus granulatus and the other snakes of the Caenophidia; the divergence time of A. meiguensis was 103 Mya, and Viperidae diverged from the unilateral of Elapidae and Colubridae was 96.06 Mya. |
