The complete mitochondrial genome of (Reptilia: Squamata) is presented for the first time in this study. It is a circular molecule of 17 415 bp in length (GenBank accession no. KU641019), consisting of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes (12S and 16S rRNA) and two control regions (D-loop), with the typical gene order and direction of transcription in Serpentes. The overall base composition is 33.65% A, 26.70% C, 13.16% G and 26.49% T. Mitochondrial genomes analyses based on NJ method yield phylogenetic trees, including 14 reported snakes belonging to four families (Colubridae, Elapidae, Viperidae and Typhlopidae). These molecular data presented here provide a useful tool for systematic analyses of genus and family Colubridae.
本研究首次展示了(爬行纲:有鳞目)的完整线粒体基因组。它是一个长度为17415 bp的环状分子(GenBank登录号KU641019),由13个蛋白质编码基因、22个转运RNA基因、两个核糖体RNA基因(12S和16S rRNA)和两个控制区(D环)组成,具有蛇亚目典型的基因排列顺序和转录方向。总体碱基组成为33.65%的A、26.70%的C、13.16%的G和26.49%的T。基于NJ方法的线粒体基因组分析产生了系统发育树,其中包括14种已报道的属于四个科(游蛇科、眼镜蛇科、蝰蛇科和盲蛇科)的蛇。这里呈现的这些分子数据为游蛇属和游蛇科的系统分析提供了一个有用的工具。
