Abstract

The structure and composition of the mitogenome of a bivalve mollusk, denoted as Mactra sp. (MT780813), has been obtained. The genome has a variable organization: it includes 12 protein-coding genes, 28 tRNAs, and two rRNA genes. Its content is sufficiently different from that of nearest specimen, accessed from GenBank, supposedly belonging to the other gender. All genes are encoded on the “+”-strand. All protein-coding genes are initiated with ATG codon. Analysis confirms the close topological position of the GenBank Mactra chinensis (KJ754823) and our M. sp. specimen on gene tree. Above data suggesting female- vs. male-type mitogenomes or cryptic species presence.

 抽象的

双壳类软体动物（Mactra sp）线粒体基因组的结构和组成。 (MT780813)，已获得。基因组具有可变的组织：它包括 12 个蛋白质编码基因、28 个 tRNA 和两个 rRNA 基因。它的内容与从 GenBank 获取的最接近的样本有很大不同，据称属于异性。所有基因都编码在“+”链上。所有蛋白质编码基因均以 ATG 密码子起始。分析证实了 GenBank Mactra chinensis (KJ754823) 和我们的 M. sp. 的拓扑位置接近。基因树上的样本。上述数据表明雌性与雄性型有丝分裂基因组或神秘物种的存在。
