The complete mitochondrial genome of Paegniodes cupulatus (Ephemeroptera: Heptageniidae)

Abstract

The complete mitochondrial genome of Paegniodes cupulatus (Ephemeroptera: Heptageniidae), which is sequenced for the first time here, is 15,715 bp in length, containing 13 protein-coding genes, 2 rRNAs, 22 tRNAs and a control region. The overall base composition of the genome is 33.1% for T, 20.7% for C, 32.5% for A and 13.7% for G, with an AT bias of 65.6%.

The complete mitochondrial genome of Epeorus herklotsi (Ephemeroptera: Heptageniidae) from Longquan, Zhejiang, China and its phylogeny

“…ATP6, ATP8, COI, COIII, ND1, ND2, ND4L, ND6 genes were terminated with TAA as stop codon, Cyt b ended with TAG and the other protein-coding genes ended with an incomplete stop codon (TA or T). An IMQM tRNA cluster at the upstream of ND2 gene was found, which was consistent with P. youi (Zhang et al 2008) and three species of Epeorus (Tang et al 2014;Gao et al 2018), while it was different to Paegniodes cupulatus with the typical IQM tRNA cluster (Zhou et al 2016).…”

The complete mitochondrial genome of Epeorus herklotsi (Ephemeroptera: Heptageniidae) and its phylogeny

“…The mt genome of E. herklotsi is a circular molecule of 15,801 bp in length, with the overall base composition of 32.7% A, 32.9% T, 21.5% C, 13.0% G, including extra tRNA Met gene. The gene rearrangement with IMQM tRNA cluster was found in E. herklotsi, which is similar to P. youi (Zhang et al 2008) and two species of Epeorus (KM244708, KJ493406) (Tang et al 2014), while is different to Paegniodes cupulatus with the typical IQM tRNA cluster (Zhou et al 2016).…”

“…The phylogenetic relationships of Ephemeroptera using morphological or molecular methods still exists disputes (Kristensen 1981;Ogden and Whiting 2003;Zhang et al 2008;Simon and Hadrys 2013;Li et al 2014;Misof et al 2014). Thirteen complete mitochondrial genomes and six partial mitochondrial genomes of Ephemeroptera are available (Zhang et al 2008;Li et al 2014;Tang et al 2014;Zhou et al 2016). In the 19 known mayfly mitochondrial genomes, gene rearrangements are found in five species (e.g.…”

The complete mitochondrial genome of Choroterpides apiculata (Ephemeroptera: Leptophlebiidae) and its phylogenetic relationships

“…Siphluriscus chinensis was used as the outgroup according to the method of Li et al (2014) and Xu et al (2020). The mitogenomes of 23 Ephemeroptera species were downloaded from GenBank (Zhang et al 2008;Li et al 2014;Tang et al 2014;Zhou et al 2016;Cai et al 2018;Gao et al 2018;Ye et al 2018;Xu et al 2020) and used to investigate the phylogenetic relationships. In order to select the conserved regions of nucleotides, each alignment was performed by Gblock 0.91 b (Castresana 2000) using the default settings.…”
