Abstract

Hynobius dunni is a salamander species of the genus Hynobius endemically distributed in eastern Kyushu in southwestern Japan. In this study, we determined the complete mitochondrial genome sequence and clarified the phylogenetic position of this species. The mitochondrial genome was 16,47 bp in length and encoded 13 protein, 2 ribosomal RNA, and 22 transfer RNA genes. Phylogenetic tree based on 13 protein-coding genes revealed that H. nebulosus were the most closely related species within the Hynobius species. The data identified in this study will be useful for population and conservation genetic studies of Hynobius species.

摘要

小鲵dunni是属蝾螈物种东北小地方性分布在九州东日本西南部。在这项研究中，我们确定了完整的线粒体基因组序列，并阐明了该物种的系统发生位置。线粒体基因组的长度为16,47 bp，编码13个蛋白质，2个核糖体RNA和22个转移RNA基因。基于13个蛋白质编码基因的系统进化树显示，H。nebulosus是Hynobius物种中最密切相关的物种。这项研究中确定的数据将对Hynobius物种的种群和保护遗传研究有用。
