The first complete mitochondrial genome of the dart sac-bearing camaenid Möllendorff, 1899 was sequenced and analyzed in this study. The whole mitogenome of Möllendorff, 1899 was 14,660 bp in length and its nucleotide composition showed high AT-content of 67.45%. It had 37 genes, including 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes. The phylogeny yielded by both Bayesian inference and maximum-likelihood method suggested that was closely related to the other dart sac-bearing camaenids with known complete mitochondrial genome. These genetic data are expected to provide fundamental resources for further genetic studies on the camaenids.
本研究对1899年的带 dart囊的莫氏山蜗牛(Möllendorff, 1899)的首个完整线粒体基因组进行了测序和分析。1899年的莫氏山蜗牛的完整线粒体基因组长度为14,660 bp,其核苷酸组成显示出较高的AT含量,为67.45%。它有37个基因,包括13个蛋白质编码基因、两个核糖体RNA基因和22个转运RNA基因。贝叶斯推断和最大似然法得出的系统发育结果表明,它与其他已知完整线粒体基因组的带dart囊的莫氏山蜗牛密切相关。这些遗传数据有望为进一步开展对莫氏山蜗牛的遗传学研究提供基础资源。
