In this study, the complete mitochondrial genome of Norwegian skates imported to Korea was sequenced with a circular molecule of 17,121 bp, which consisted of 13 protein-coding genes (PCGs), 2 ribosomal RNAs, 22 transfer RNA genes, and a control region (D-loop). And among these sequences, 193 bp sequence in the D-loop of the genus suggested the possibility of being used as a genetic marker for classification of and species. The BI phylogenetic tree by using the nucleotide sequences of 13 PCGs from 15 available mitogenomes of family Rajidae confirmed also that Norwegian skates imported to Korea form a group with species with high branch value, and that this was a species of . As above, these results would be expected to provide for the further understanding on the phylogenetic relationship, taxonomic classification and phylogeography of the family Rajidae.
在本研究中，对进口到韩国的挪威鳐的完整线粒体基因组进行了测序，其为一个17,121 bp的环状分子，由13个蛋白质编码基因（PCGs）、2个核糖体RNA、22个转运RNA基因和一个控制区（D环）组成。在这些序列中，该属D环中的193 bp序列表明其有可能用作该属和该物种分类的遗传标记。利用来自鳐科15个可用线粒体基因组的13个PCGs的核苷酸序列构建的贝叶斯系统发育树也证实，进口到韩国的挪威鳐与该物种形成一个具有高分支值的类群，且这是该物种的一个种类。如上所述，这些结果有望为进一步了解鳐科的系统发育关系、分类学分类和系统地理学提供依据。
