Mitochondrial DNA. 2014 Apr;25(2):98-9. doi: 10.3109/19401736.2013.784754. Epub 2013 Apr 16.
Culter dabryi, a medium-sized economic cyprinid fish, is widely distributed in East Asia. We sequenced the complete mitochondrial genome of this species. The genome is 16,622 bp in length, and consists of 22 transfer RNA genes, 13 protein-coding genes, two ribosomal RNA genes and the non-coding control region with a structural organization conserved relative to that of other fishes. The overall base composition of C. dabryi in descending order is A 31.51%, C 27.60%, T 24.95% and G 15.94%, with a slight A + T bias. The mitogenome sequence data may provide useful information to the population genetics analysis of C. dabryi and the elucidation of evolutionary mechanisms in the endemic clade of East Asian Cyprinidae.
达氏鲴是一种中型经济鲤科鱼类，广泛分布于东亚地区。我们对该物种的线粒体全基因组进行了测序。该基因组长度为16,622 bp，由22个转运RNA基因、13个蛋白质编码基因、两个核糖体RNA基因以及非编码控制区组成，其结构组织相对于其他鱼类而言具有保守性。达氏鲴的总体碱基组成从高到低依次为：A 31.51%、C 27.60%、T 24.95%、G 15.94%，略偏向于A+T。线粒体基因组序列数据可能为达氏鲴的群体遗传学分析以及东亚鲤科特有分支进化机制的阐明提供有用信息。
