在这项工作中，我们报道了复制冠冠鱼的完整线粒体基因组。线粒体基因组全长16,667个核苷酸，碱基组成分别为32.90%A、26.55%T、25.94%C和14.61%G，包括2个核糖体RNA基因、13个蛋白质编码基因、22个转移RNA基因和一个主要的非编码控制区(D-loop区)。这些基因的排列与在志留目动物中发现的相同。除cox1以GTG开头外，所有的蛋白质起始密码子都是ATG。用极大似然法对双瓣隐翅虫等8属27种的细胞色素C氧化酶I(COX1)氨基酸序列进行了系统发育分析。拓扑学分析表明，所有物种均分为两个类群(鲤科和鲤科)，其中重瓣鲤科与纳特雷科鱼类聚为一类。
In this work, we reported the complete mitochondrial genome of Corydoras duplicareus. The total length of the mitochondrial genome is 16,667 bp, with the base composition of 32.90% A, 26.55% T, 25.94% C, and 14.61% G. It contains two ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes, and a major non-coding control region (D-loop region). The arrangement of these genes is the same as that found in the Siluriformes. All the protein initiation codons are ATG, except for cox1 that begins with GTG. The cytochrome c oxidase subunit I (COX1) amino acid sequence of C. duplicareus and other 27 species from 8 genera were used for phylogenetic analysis by maximum likelihood method. The topology demonstrated that all species are divided into two groups (Callichthyidae and Cyprinidae), and the C. duplicareus was clustered with C.nattereri.
