Abstract

In this study, the complete mitochondrial genome yielded by next-generation sequencing of C. trilineatus was assembled and analyzed. The total length of the mitochondrial genome is 16,526 bp. It contains two ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes, and a major non-coding control region . The arrangement of these genes is the same as that found in the Siluriformes. The complete mitogenomes of C. trilineatus and other 17 species from nine genera were used for phylogenetic analysis by UPGMA method. The topology demonstrated that all species are divided into three groups , and the C. trilineatus was clustered with C. rabauti and C. nattereri.

 抽象的

在本研究中，组装并分析了通过新一代测序获得的C. trilineatus的完整线粒体基因组。线粒体基因组的总长度为 16,526 bp。它包含两个核糖体RNA基因、13个蛋白质编码基因、22个转移RNA基因和一个主要非编码控制区。这些基因的排列与鲶形目中发现的相同。利用UPGMA方法对C. trilineatus和其他9属17个物种的完整线粒体基因组进行系统发育分析。拓扑结构表明，所有物种均分为三个类群，其中C. trilineatus与C. rabauti和C. nattereri聚集在一起。
