Abstract：
Electric catfishes evolved the substantial electric organ that can instantly release powerful high-voltage electricity. To better study the phylogenetic position of the electric fish (Malapterurus electricus) in catfishes, in this study, we presented the complete mitochondrial genome of M. electricus assembled by the next-generation sequencing data. The mitogenome has 16,504 bp and contains 13 protein-coding genes (PCGs), 22 transfer RNA genes, two ribosomal RNA genes, an L-strand replication origin (OL), and a control region (D-loop). The overall base composition is A 31.08%, C 27.54%, G 14.81%, and T 26.57%. Phylogenetic analysis based on 13 PCGs of 43 species from Siluriformes showed M.electricus belonging to the Malapteruridae displayed a close relationship with Siluridae. Taken together, the complete mitochondrial genome of M. electricus would be beneficial for the study of the phylogenetic relationship of Siluriformes.
摘要：
电鲶鱼进化出大量的电器官，可以立即释放强大的高压电。为了更好地研究电鱼（Malapteruruselectricus）在cat鱼中的系统发育位置，在这项研究中，我们展示了通过下一代测序数据组装的电分枝杆菌的完整线粒体基因组。有丝分裂基因组有16,504bp，包含13个蛋白质编码基因（PCGs），22个转移RNA基因，两个核糖体RNA基因，L链复制起点（OL），和控制区域(D环)。总体基础成分为31.08%，C27.54%,G14.81%,和T26.57%。基于Siluriformes43种的13个PCGs的系统发育分析表明，属于Malapteruridae的M.electricus与Siluridae有着密切的关系。一起来看,完整的线粒体基因组将有助于研究硅藻的系统发育关系。
