Transcriptome sequencing of electric fishes

We sequenced transcriptomes (RNAseq) from five species of electric fish. We performed RNAseq on skeletal muscle and electric organ from the species Sternopygus macrurus, Eigenmannia virescens, Malapterurus electricus, and Brienomyrus brachyistius. From Electrophorus electricus, we performed RNAseq on brain, spinal cord, heart, skeletal muscle, main electric organ, Sachs' electric organ, Hunter's electric organ, and kidney. With these data we provide the first comprehensive molecular analysis of electric organs in electric fishes. Additionally, we used these data the molecular basis for the convergent evolution of electric organs.

我们对五种电鱼的转录组（RNAseq）进行了测序。针对长身裸吻电鳗（Sternopygus macrurus）、绿平背电鳗（Eigenmannia virescens）、电鲶（Malapterurus electricus）及短尾弯鼻电鳗（Brienomyrus brachyistius），我们对其骨骼肌与电器官开展了RNAseq测序；对于美洲电鳗（Electrophorus electricus），我们则分别对其大脑、脊髓、心脏、骨骼肌、主电器官、萨克斯氏电器官、亨特氏电器官以及肾脏进行了RNAseq测序。基于上述数据集，我们首次实现了对电鱼电器官的全面分子分析。此外，我们借助该数据集揭示了电鱼电器官趋同演化的分子基础。
