Abstract

We report complete mitochondrial genome of Northern Indian red muntjac, Muntiacus vaginalis, and its phylogenetic inferences. Mitogenome composition was 16,352 bp in length and its overall base composition in the circular genome was A = 33.2%, T = 29.0%, C = 24.50% and G = 13.30%. It exhibited a typical mitogenome structure, including 22 transfer RNA genes, 13 protein-coding genes, two ribosomal RNA genes and a major non-coding control region (D-loop region). All the genes except ND6 and eight tRNA's were encoded on the heavy strand. Phylogenetic analyses showed that M. vaginalis is closely related to M. muntjak and formed a sister relationship with Elaphodus cephalophus. In view of the unclear distribution range and escalating habitat loss, it is important to identify its population genetic status. The complete mitogenome described in this study can be used in further phylogenetics, identification of extant maternal lineage, evolutionary significance unit and its genetic conservation.

摘要

我们报告了北印度赤麂(Muntiacus vaginalis)的完整线粒体基因组及其系统发育推断。线粒体基因组长度为16,352 bp,其环状基因组的总体碱基组成为A = 33.2%,T = 29.0%,C = 24.50%,G = 13.30%。它呈现出典型的线粒体基因组结构,包括22个转运RNA基因、13个蛋白质编码基因、两个核糖体RNA基因和一个主要的非编码控制区(D环区)。除ND6和8个tRNA外,所有基因均在重链上编码。系统发育分析表明,赤麂与黑麂密切相关,并与毛冠鹿形成姐妹关系。鉴于其分布范围不明且栖息地丧失不断加剧,确定其种群遗传状况很重要。本研究中描述的完整线粒体基因组可用于进一步的系统发育研究、现存母系谱系的鉴定、进化意义单元及其遗传保护。
