Complete mitochondrial genomes of Epeorus carinatus and E. dayongensis (Ephemeroptera: Heptageniidae): Genomic comparison and phylogenetic inference.

摘要: Abstract The current research on Ephemeroptera is mainly based its morphology, since only small numbers of mitogenomes have been reported. In this study, the Epeorus carinatus (15,338 bp) and E. dayongensis (15,609 bp) were sequenced, annotated compared to genome data from congeners. Both had 23 tRNA genes including standard 22 one extra tRNAMet. duplicated tRNAMet gene found in other heptageniid species except Paegniodes cupulatus, suggesting it could be used as a molecular synapomorphy for partial Heptageniidae. phylogenetic analyses Bayesian Inference (BI) Maximum Likelihood (ML) showed that Heptageniidae was monophyletic relationships among known ((E. carinatus + E. herklotsi) + (E. dayongensis + E. sp. 1)), which implied focal should grouped into different subgenera.
