We present the complete mitochondrial genome sequence of a recently described new leech species named Yang & Bolotov 2021 collected in central China. The mitochondrial genome is 14,984 bp in length and consists of 13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA genes, all of which are encoded on a single strand. It exhibited a strong A + T bias of 72.87%. There is a large non-coding region (614 bp) located between the and genes, wherein we identified 40 short dispersed repeats, 13-22 bp long, 8 of which were direct, 20 inverted, and 12 palindromic. Phylogenetic analysis of 20 Hirudinea mitogenome sequences resolved monophyletic Glossiphoniidae, and formed a sister lineage with
我们展示了最近在中国中部采集的一种名为Yang & Bolotov 2021的新水蛭物种的完整线粒体基因组序列。线粒体基因组长度为14,984 bp,由13个蛋白质编码基因、2个核糖体RNA基因和22个转移RNA基因组成,所有这些基因都编码在一条单链上。它表现出强烈的A+T偏向性,为72.87%。在 和 基因之间有一个大的非编码区(614 bp),我们在其中鉴定出40个短分散重复序列,长度为13 - 22 bp,其中8个是正向的,20个是反向的,12个是回文的。对20条水蛭线粒体基因组序列的系统发育分析解析出单系的舌蛭科,并且 与 形成了姐妹谱系
