Mitochondrial DNA A DNA Mapp Seq Anal. 2016 Sep;27(5):3444-5. doi: 10.3109/19401736.2015.1063134. Epub 2015 Aug 10.
The complete mitochondrial genome of the Ephippus orbis has been sequenced. The mitochondrial genome is 16 670 bp in length, containing 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and one control region. The gene order and the composition of E. orbis mitochondrial genome were similar to that of most other vertebrates. The overall nucleotides base composition of the heavy strand is A (27.17%), G (16.41%), C (31.46%), and T (24.96%). With the exception of the NADH dehydrogenase subunit 6 (ND6) and eight tRNA genes, all other mitochondrial genes are encoded on the heavy strand. Seen from the phylogenetic tree ( Figure 1 ), E. orbis, Platax teira, and Platax orbicularis from the same family (Ephippidae) clustered into one branch and were significantly divergent from the other families of closely related fish species.
已对圆腹燕鱼(Ephippus orbis)的完整线粒体基因组进行了测序。线粒体基因组长度为16670 bp,包含13个蛋白质编码基因、2个核糖体RNA基因、22个转运RNA基因和一个控制区。圆腹燕鱼线粒体基因组的基因顺序和组成与大多数其他脊椎动物相似。重链的总体核苷酸碱基组成为A(27.17%)、G(16.41%)、C(31.46%)和T(24.96%)。除了NADH脱氢酶亚基6(ND6)和8个tRNA基因外,所有其他线粒体基因都在重链上编码。从系统发育树(图1)可以看出,来自同一家族(燕鱼科)的圆腹燕鱼、尖翅燕鱼(Platax teira)和圆燕鱼(Platax orbicularis)聚为一个分支,与其他亲缘关系密切的鱼类家族有显著差异。
