We determined the complete mitochondrial genome of The mitochondrial genome is 16,100 bp in length, comprising 13 protein-coding genes, 22 transfer RNA genes, and two ribosomal RNA genes. The nucleotide composition for is 17.5% of C, 16.88% of G, 35.3% of T, and 30.31% 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, and nad2 genes stop with TAG, and 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 tree showed that the is closely related to the Semisulcospira coreana 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[物种名称未给出]的完整线粒体基因组。该线粒体基因组长度为16,100 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17.5%，G占16.88%，T占35.3%，A占30.31%。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和nad2基因以TAG终止，其他九个基因以TAA终止。在已鉴定的这37个基因中，九个蛋白质编码基因和六个转运RNA基因由重链编码，其他基因由轻链编码。基于[物种名称未给出]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[外类群物种名称未给出]作为外类群，采用邻接法。该树显示[物种名称未给出]与Cerithioidea中的Semisulcospira coreana密切相关。我们相信这一结果将有助于滨螺科的种群遗传学和系统发育分析研究。
