腹足纲包括大量已描述的物种，许多具有广泛重排的线粒体基因组。我们测序的岩石壳，Thais clavigera（腹足纲：Muricidae），潮间带蜗牛的有丝分裂基因组，使用长PCR与表达序列标签的基础上设计的引物。T. clavigera由2个rRNA、22个tRNA和13个蛋白质编码基因组成，但没有控制区。结构比较表明，Sorbeoconcha，包括T。clavigera，具有几乎相同的线粒体基因模式。然而，它们在包含21个基因的tRNAPhe-tRNAGlu簇之间有一个倒位，但其余大部分结构与推定的软体动物地面模式相似。这些发现将为腹足类进化过程中线粒体基因重排提供更好的见解。(C)2009 Elsevier Inc.

Class Gastropoda includes a large number of described species, many with extensively rearranged mitochondrial genomes. We sequenced the mitogenome of the rock shell, Thais clavigera (Gastropoda: Muricidae), an intertidal snail, using long PCR with primers designed on the basis of expressed sequence tags. The mitogenome of T. clavigera consists of 2 rRNAs, 22 tRNAs, and 13 protein-coding genes, but no control region. Structural comparisons revealed that the order Sorbeoconcha, including T. clavigera, have nearly identical mitochondrial gene patterns. However, they have an inversion between a tRNAPhe-tRNAGlu cluster that comprises 21 genes, but most of the remaining structure is similar to the putative mollusk ground pattern. These findings will provide a better insight into mitochondrial gene rearrangement over the Course of gastropod evolution. (C) 2009 Elsevier Inc. All rights reserved.
