“…Generally, an animal mitogenome is a double-stranded circular molecule, ranging from 14 to 20 kb in length and containing a typical set of 37 genes, including 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, and two ribosomal RNA (rRNA) genes (Taanman 1999). Functional information on replication derived from the related genomic structures has been well investigated, but the transcription features of animal mitogenomes are still limited (Chen and Du 2017). Here, we sequenced and assembled the mitogenome of S. mutilans and compared its genome to seven other representative centipede mitogenomes derived from Scolopendromorpha, Geophilomorpha, Lithobiomorpha, and Scutigeromorpha.…”

Scolopendra mutilans L. Koch, 1878 is an important Chinese animal with thousands of years of medicinal history. However, the genomic information of this species is limited, which hinders its further application. Here, the complete mitochondrial genome (mitogenome) of S. mutilans was sequenced and assembled by next-generation sequencing. The genome is 15,011 bp in length, consisting of 13 protein-coding genes (PCGs), 14 tRNA genes, and two rRNA genes. Most PCGs start with the ATN initiation codon, and all PCGs have the conventional stop codons TAA and TAG. The S. mutilans mitogenome revealed nine simple sequence repeats (SSRs), and an obviously lower GC content compared with other seven centipede mitogenomes previously sequenced. After analysis of homologous regions between the eight centipede mitogenomes, the S. mutilans mitogenome further showed clear genomic rearrangements. The phylogenetic analysis of eight centipedes using 13 conserved PCG genes was finally performed. The phylogenetic reconstructions showed Scutigeromorpha as a separate group, and Scolopendromorpha in a sister-group relationship with Lithobiomorpha and Geophilomorpha. Collectively, the S. mutilans mitogenome provided new genomic resources, which will improve its medicinal research and applications in the future.

“…Insect mitogenomes are closed-circular molecules of approximately 16 kb in length, with 37 genes and a noncoding A + T-rich region [32][33][34][35][36]. Mitogenomes have been widely utilized to analyze population genetics, phylogeography, and molecular phylogenetics at different taxonomic levels [37][38][39][40].…”

A complete mitogenome of Trachys auricollis is reported, and a mitogenome-based phylogenetic tree of Elateriformia with all protein-coding genes (PCGs), rRNAs, and tRNAs is presented for the first time. The complete mitochondrial genome of T. auricollis is 16,429 bp in size and contains 13 PCGs, two rRNA genes, 22 tRNA genes, and an A + T-rich region. The A + T content of the entire genome is approximately 71.1%, and the AT skew and GC skew are 0.10 and −0.20, respectively. According to the the nonsynonymous substitution rate to synonymous substitution rates (Ka/Ks) of all PCGs, the highest and lowest evolutionary rates were observed for atp8 and cox1, respectively, which is a common finding among animals. The start codons of all PCGs are the typical ATN. Ten PCGs have complete stop codons, but three have incomplete stop codons with T or TA. As calculated based on the relative synonymous codon usage (RSCU) values, UUA(L) is the codon with the highest frequency. Except for trnS1, all 22 tRNA genes exhibit typical cloverleaf structures. The A + T-rich region of T. auricollis is located between rrnS and the trnI-trnG-trnM gene cluster, with six 72-bp tandem repeats. Both maximum likelihood (ML) and Bayesian (BI) trees suggest that Buprestoidea is close to Byrrhoidea and that Buprestoidea and Byrrhoidea are sister groups of Elateroidea, but the position of Psephenidae is undetermined. The inclusion of tRNAs might help to resolve the phylogeny of Coleoptera.

“…The phylogenetic position of the family Nemouridae has been performed based on morphological or mitochondrial genome data previously, while there are still many different viewpoints to date (Zwick 2000;Du 2017, 2018;Wang et al 2019). Two mitochondrial genomes of genus Nemoura have been reported previously (Chen and Du 2017;, we sequenced and assembled the complete mitochondrial genome of N. meniscata from Longyuwan, Henan Province, China (33.699 N, 111.809 E) with the GenBank accession number MN944386 by using the highthroughput sequencing method in this study. The male specimen with the number VHL-0042 was collected on 15 May 2016 by Weihai Li and Junchao Wang.…”

We sequenced the third complete mitochondrial genome of Nemoura meniscataby using the highthroughput sequencing method. The mitochondrial genome harbored 37 typical code genes and a control region with 15,895 bp in length was a double-stranded and circular genome. The nucleotide composition is partial to A and T. Seventy-eight nucleotides were dispersed in 10 intergenic spacers and gene overlaps were also found at 13 gene junctions with 48 nucleotides. In phylogenetic trees, the 13 Nemouridae species form a clade diverged from the outgroup clade. The genus Nemoura and Amphinemura were sister groups which is consistent with the previous study.
