We describe the complete mitochondrial genome sequence of the Black Lion Tamarin, an endangered primate species endemic to the Atlantic Rainforest of Brazil. We assembled the mitogenome, through analysis of 523M base pairs (bp) of short reads produced by next-generation sequencing (NGS) on the Illumina Platform, and investigated the presence of nuclear mitochondrial pseudogenes and heteroplasmic sites. Additionally, we conducted phylogenetic analyses using all complete mitogenomes available for primates until June 2017. The single circular mitogenome of BLT showed organization and arrangement that are typical for other vertebrate species, with a total of 16618 bp, containing 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and 1 non-coding region (D-loop region). Our full phylogenetic tree is based on the most comprehensive mitogenomic dataset for Callitrichidae species to date, adding new data for the genus, and discussing previous studies performed on primates. Moreover, the mitochondrial genome reported here consists of a robust mitogenome with 3000X coverage, which certainly will be useful for further phylogenetic and evolutionary analyses of Callitrichidae and higher taxa.
我们描述了黑狮狨的完整线粒体基因组序列,黑狮狨是一种濒危灵长类动物,原产于巴西的大西洋雨林。我们通过对Illumina平台上的下一代测序(NGS)产生的5.23亿碱基对(bp)短读长进行分析,组装了该线粒体基因组,并研究了核线粒体假基因和异质性位点的存在情况。此外,我们利用截至2017年6月所有可获得的灵长类动物完整线粒体基因组进行了系统发育分析。黑狮狨的单环状线粒体基因组显示出与其他脊椎动物物种典型的组织和排列方式,全长16618 bp,包含13个蛋白质编码基因、22个转运RNA基因、2个核糖体RNA基因和1个非编码区(D-loop区)。我们完整的系统发育树基于迄今为止绢毛猴科物种最全面的线粒体基因组数据集,为该属增添了新数据,并讨论了之前对灵长类动物进行的研究。此外,这里报道的线粒体基因组由一个覆盖度为3000倍的强大线粒体基因组组成,这肯定将有助于绢毛猴科及更高分类群的进一步系统发育和进化分析。
