The complete mitochondrial genome of a widely distributed pelagic ray, the Spinetail Devilray (Mobula japanica), consists of 18,880 bp with high A+T and low G content. Gene configuration and length is similar to other vertebrates and comprises 13 protein-coding genes, 2 rRNAs genes (12S and 16S rRNA), 22 tRNAs genes, and 1 major non-coding sequence, the control region. A remarkable feature in the mitochondrial genome of M. japanica is three tandemly repeated areas in the control region, together comprising a length of almost 1500 bp, making this to our knowledge the longest elasmobranch mitochondrial genome published so far.
广泛分布的远洋鳐类——日本蝠鲼(Mobula japanica)的完整线粒体基因组由18,880个碱基对组成,具有高A+T含量和低G含量。基因结构和长度与其他脊椎动物相似,包括13个蛋白质编码基因、2个rRNA基因(12S和16S rRNA)、22个tRNA基因以及1个主要的非编码序列,即控制区。日本蝠鲼线粒体基因组的一个显著特征是控制区有三个串联重复区域,总长近1500个碱基对,据我们所知,这使得它成为迄今为止已发表的最长的板鳃亚纲线粒体基因组。
