We present the complete mitochondrial genome of in this study. The mitochondrial genome is 15,512 bp in length, containing 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes. Overall nucleotide compositions of the light strand are 41.13% of A, 30.81% of T, 15.25% of C and 12.81% of G. Its gene arrangement and distribution are different from the typical vertebrates. The absence of D-loop is consistent with the Gastropoda, but at least one lengthy non-coding region is essential regulatory element for the initiation of transcription and replication. Phylogenetic tree is constructed by the maximum-likelihood method based on the complete mitochondrial genomes of 15 species of Caenogastropoda, using as outgroup to assess their actual phylogenetic relationship and evolution. The result provides fundamental data for resolving phylogenetic and genetic problems related to effective management strategies.
在本研究中，我们展示了[物种名称]的完整线粒体基因组。线粒体基因组长度为15,512 bp，包含13个蛋白质编码基因、2个rRNA基因和22个tRNA基因。轻链的总体核苷酸组成是：A占41.13%，T占30.81%，C占15.25%，G占12.81%。其基因排列和分布与典型脊椎动物不同。D环的缺失与腹足纲动物一致，但至少一个长的非编码区域是转录和复制起始的重要调控元件。基于15种新腹足目的完整线粒体基因组，采用最大似然法构建系统发育树，以[外类群名称]作为外类群来评估它们实际的系统发育关系和进化。该结果为解决与有效管理策略相关的系统发育和遗传问题提供了基础数据。
