The mitochondrial genome (mitogenome) is a powerful tool that is extensively used in genomic and phylogenetic analysis. In this study, the complete mitogenome of the toothed top shell snail () has been sequenced and annotated for the first time. The complete circular genome is 16,440 bp in length including 13 protein-coding genes, 22 transfer RNA and two ribosomal RNA genes. All of the protein-coding genes use the standard initiation codon ATN and are terminated by the termination codons TAA and TAG. All of the tRNA genes have the typical clover leaf structure, with the exception of the tRNA-Asp, which lacks aTψC arm, and tRNA-Ser(AGN), which lacks a DHU arm. Relatively short intergenic spacers and overlaps are observed in this mitogenome. Our phylogenetic tree shows that is clustered together with other species within Trochidae. The complete mitogenome of provide essential DNA data for evolutionary and phylogenetic analysis of marine gastropods.
线粒体基因组（线粒体基因组）是一种强大的工具，广泛用于基因组和系统发育分析。在本研究中，首次对齿顶壳蜗牛（）的完整线粒体基因组进行了测序和注释。完整的环状基因组长度为16,440 bp，包括13个蛋白质编码基因、22个转运RNA和两个核糖体RNA基因。所有蛋白质编码基因均使用标准起始密码子ATN，并由终止密码子TAA和TAG终止。除了缺少aTψC臂的tRNA-Asp和缺少DHU臂的tRNA-Ser(AGN)外，所有tRNA基因都具有典型的三叶草叶结构。在这个线粒体基因组中观察到相对较短的基因间隔区和重叠区。我们的系统发育树表明，与Trochidae科内的其他物种聚集在一起。的完整线粒体基因组为海洋腹足类动物的进化和系统发育分析提供了重要的DNA数据。
