Abstract

We report the complete mitogenome of , which is 17,750 bp in size and includes 13 protein-coding (PCGs), 2 rRNA genes, 22 tRNA genes, and 2 control regions. PCGs, with 13 genes, is 11,427 bp in length. All PCGs use ATN as the typical start codon except COX1 with GTG; the TAG was found as the stop codon in ND1 and ND2, the AGA was found as the stop codon in COI and ND6, the TAA was found as the stop codon in ATP8, ATP6, ND4L, ND5 and Cytb; while other 3 PCGs stop with a single T. Phylogeny reconstructed using the Bayesian inference (BI) method with 13 PCGs indicates the presence of at the root of Laticaudinae.

摘要

我们报告了[物种名称]的完整线粒体基因组,其大小为17,750 bp,包括13个蛋白质编码基因(PCGs)、2个rRNA基因、22个tRNA基因和2个控制区。13个基因的PCGs长度为11,427 bp。除COX1以GTG作为起始密码子外,所有PCGs均以ATN作为典型起始密码子;在ND1和ND2中发现TAG为终止密码子,在COI和ND6中发现AGA为终止密码子,在ATP8、ATP6、ND4L、ND5和Cytb中发现TAA为终止密码子;而其他3个PCGs以单个T作为终止密码子。使用贝叶斯推断(BI)方法基于13个PCGs重建的系统发育表明,在海蛇亚科的根部存在[物种名称]。
