Mitochondrial DNA A DNA Mapp Seq Anal. 2017 Mar;28(2):216-217. doi: 10.3109/19401736.2015.1115848. Epub 2015 Dec 29.
We obtained the complete mitochondrial genome of the Ussuri white-toothed shrew Crocidura lasiura (Insectivora, Soricidae) at 17 362 base pairs (bp) containing 13 protein-coding genes, two ribosomal RNAs, 22 transfer RNAs, and a non-coding control region. Its gene order is identical to that of other vertebrates. Several repeat elements were identified in the non-coding control region (D-loop). Phylogenetic tree using mt protein-coding gene sequences showed that C. lasiura was closely related to C. attenuata. The reports of mt genome sequences of Crocidura were not enough to study phylogenetic relationships in genome levels. However, this report may help us to understand the phylogenetic relationships and evolutionary history of Crocidura.
我们获得了乌苏里白齿鼩（Crocidura lasiura，食虫目，鼩鼱科）的完整线粒体基因组，其长度为17362个碱基对（bp），包含13个蛋白质编码基因、两个核糖体RNA、22个转运RNA和一个非编码控制区。其基因排列顺序与其他脊椎动物相同。在非编码控制区（D环）中鉴定出了几个重复元件。使用线粒体蛋白质编码基因序列构建的系统发育树表明，乌苏里白齿鼩与长尾白齿鼩（C. attenuata）关系密切。关于白齿鼩线粒体基因组序列的报道不足以在基因组水平上研究系统发育关系。然而，本报告可能有助于我们了解白齿鼩的系统发育关系和进化历史。
