Abstract

The complete mitochondrial genome of the Omphalius rusticus has been determined. The complete genome is 18,067 bp and contained 13 protein-coding genes, two rRNA genes and 22 tRNA genes. The overall base composition is 33.48% (A), 33.52% (T), 15.58% (G) and 17.42% (C). The all start codon for 13 protein-coding genes is ATG and the most common termination codon is TAA. The phylogenetic tree showed that O. rusticus is most closely related to the Tectus pyramis. We suggest that this result will further supplement the genome information in mitochondria of the family Tegulidae and facilitate the study on population genetics.

摘要

已经确定了Omphalius Rustus的完整线粒体基因组。完整的基因组为18,067 bp，包含13个蛋白质编码基因，两个rRNA基因和22个tRNA基因。总体碱组成为33.48％（A），33.52％（T），15.58％（G）和17.42％（C）。13个蛋白质编码基因的全部起始密码子是ATG，最常见的终止密码子是TAA。系统进化树表明，O.rustus与Tectus pyramis关系最为密切。我们认为，该结果将进一步补充特古利科（Tegulidae）线粒体中的基因组信息，并促进对群体遗传学的研究。
