In the present study, the complete mitogenome sequence of a Dybowsky from Cao'e River was sequenced and identified. The assembled mitogenome of is 16,676bp in length, it contains 22 transfer-RNA genes, 13 protein-coding genes, 2 ribosomal-RNA genes, and 2 non-coding regions. It shows conserved gene arrangement with other Cyprinidae fishes. The overall nucleotide composition of mitogenome sequence is A: 28.96%, G: 17.11%, T: 27.46%, and C: 26.47%. The phylogenetic analysis showed that the complete mitogenome could contribute to the phylogenetic analyses and population genetics study of and fish.
在本研究中，对一条采自曹娥江的戴氏鲌的完整线粒体基因组序列进行了测序和鉴定。组装后的戴氏鲌线粒体基因组长度为16,676bp，包含22个转运RNA基因、13个蛋白质编码基因、2个核糖体RNA基因和2个非编码区。它与其他鲤科鱼类显示出保守的基因排列。戴氏鲌线粒体基因组序列的总体核苷酸组成为：A：28.96%，G：17.11%，T：27.46%，C：26.47%。系统发育分析表明，完整的线粒体基因组有助于戴氏鲌及相关鱼类的系统发育分析和群体遗传学研究。
