We determined the complete mitochondrial genome of The mitochondrial genome is 15748 bp in length, comprising 13 protein-coding genes, 22 transfer RNA genes, and two ribosomal RNA genes. The nucleotide composition for is 17.71% of C, 16.74% of G, 34.99% of T, and 30.3% of A. In 13 protein-coding genes, all genes start with ATG. For the stop codon, the cox2 gene stops with TTC, the cytb, nad1, nad2 genes stop with TAG, the other nine genes are with TAA. Of these 37 genes identified, nine protein-coding genes and six transfer RNA genes are encoded on the heavy strand and the other genes on the light strand. The phylogenetic tree was constructed based on 13 protein-coding genes of the and other 19 Gastropoda species, as outgroup using the Neighbour-joining method. The result showed that is most closely related to the in Cerithioidea. We believe that this result will be helpful for the study of population genetic and phylogenetic analysis of the family Batillariidae.
我们测定了[物种名称]的完整线粒体基因组。该线粒体基因组长度为15748 bp，包含13个蛋白质编码基因、22个转运RNA基因和两个核糖体RNA基因。其核苷酸组成为：C占17.71%，G占16.74%，T占34.99%，A占30.3%。在13个蛋白质编码基因中，所有基因均以ATG起始。对于终止密码子，cox2基因以TTC终止，cytb、nad1、nad2基因以TAG终止，其他9个基因以TAA终止。在这些已鉴定的37个基因中，9个蛋白质编码基因和6个转运RNA基因在重链上编码，其他基因在轻链上编码。基于[物种名称]的13个蛋白质编码基因以及其他19种腹足纲物种构建了系统发育树，以[外类群名称]作为外类群，采用邻接法。结果表明，[物种名称]与蜒螺超科中的[相关物种名称]关系最为密切。我们相信这一结果将有助于笠贝科的群体遗传学和系统发育分析研究。
