The complete mitogenomes of four species, Neptis thisbe, Neptis obscurior, Athyma zeroca, and Aldania raddei, were sequenced with sizes ranging from 15,172 bp (N. obscurior) to 16,348 bp (Al. raddei). All four mitogenomes display similar nucleotide content and codon usage of protein-coding genes (PCGs). Typical cloverleaf secondary structures are identified in 21 tRNA genes, while trnS1 (AGN) lacks the dihydrouridine (DHC) arm. The gene orientation and arrangement of the four mitogenomes are similar to that of other typical mitogenomes of Lepidoptera. The Ka/Ks ratio of 13 PCGs among 58 Limenitidinae species reveals that cox1 had the slowest evolutionary rate, while atp8 and nad6 exhibited a higher evolutionary rate. The phylogenetic analysis reveals that tribe-levels are well-supported monophyletic groups. Additionally, Maximum Likelihood analysis recovered the relationship (Parthenini + ((Chalingini + (Cymothoini + Neptini)) + (Adoliadini + Limenitidini))). However, a Bayesian analysis based on the same dataset recovered the relationship (Parthenini + (Adoliadini + ((Cymothoini + Neptini) + (Chalingini + Limenitidini)))). These results will offer valuable data for the future study of the phylogenetic relationships for Limenitidinae.

Background: Genome-scale approaches have played a significant role in the analysis of evolutionary relationships. Because of rich polymorphisms, high evolutionary rate and rare recombination, mitochondrial DNA sequences are commonly considered as effective markers for estimating population genetics, evolutionary and phylogenetic relationships. Flying fishes are important components of epipelagic ecosystems. Up to now, only few complete mitochondrial genomes of flying fishes have been reported. In the present study, the complete mitochondrial DNA sequences of the Cheilopogon pinnatibarbatus japonicus and Hirundichthys rondeletii had been determined. Methods: Based on the published mitogenome of Cheilopogon atrisignis (GenBank: KU360729), fifteen pairs of primers were designed by the software Primer Premier 5.0 to get the complete mitochondrial genomes of two flying fishes. According to the reported data, the phylogenetic position of two flying fishes were detected using the conserved 12 protein-coding genes. Result: The complete mitochondrial genomes of Cheilopogon pinnatibarbatus japonicus and Hirundichthys rondeletii are determined. They are 16532bp and 16525bp in length, respectively. And they both consists of 13 protein-coding genes, 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes and a control region. The OL regions are conserved in these two flying fishes and might have no function. From the tree topologies, we found C.p. japonicus and H. rondeletii clustered in a group. The findings of the study would contribute to the phylogenetic classification and the genetic conservation management of C.p. japonicus and H. rondeletii.

AbstractWe are presenting the complete mitogenomes of eight fish species/cytotypes from Neotropical region belonging to the Astyanax and Psalidodon genus: A. aeneus, A. altiparanae, P. fasciatus (from two locations - Upper Paraná and São Francisco river basins), A. lacustris, P. rivularis (two cytotypes) and P. rioparanaibano. We perform the whole-genome sequencing for six of these species in a Novaseq 6000 - by Illumina, meanwhile two genomes were assembled from raw data available in databases. Plus, we reassembled and annotated the mitochondrial genomes for A. mexicanus and P. paranae, both already described and with raw data available online. All the genomes presented the same organization, with 13 protein-coding genes, 22 tRNA genes and two rRNA genes. Aiming to contribute to the understanding of the several cryptic species complexes and phylogeny of the genus, we perform Bayesian analysis using the 13 protein-coding genes from these species, plus Deuterodon giton and using a Brycon species as outgroup.

Abstract Background: Mitochondrial genomes play a significant role in reconstructing phylogenetic relationships and revealing molecular evolution in insects. However, only two species of Panorpidae have been documented for mitochondrial genomes in Mecoptera to date.Results: We obtained complete mitochondrial genomes of 17 species of Panorpidae. The results show that the complete mitogenome sequences of Panorpidae all contain 37 genes (13 protein-coding genes (PCGs), two rRNAs, 22 tRNAs) and one control region. The mitogenomes exhibit a strong AT bias. The AT-skew can either be slightly positive or slightly negative, while the GC-skew is usually negative. The 22 tRNA genes can fold into a common cloverleaf secondary structure except trnS1. The sliding window and genetic distance analyses demonstrate highly variable nucleotide diversity among the 13 protein-coding genes, with comparatively low evolutionary rate of cox1, cox2 and nad1, and high variability of nad2 and nad6. The phylogeny of Panorpidae can be presented as (Neopanorpa + Furcatopanorpa) + (Dicerapanorpa + (Panorpa debilis + (Sinopanorpa + (Cerapanorpa + Panorpa)))).Conclusions: Our analyses indicate that the genes nad2 and nad6 can be regarded as potential markers for population genetics and species delimitation in Panorpidae. Panorpa is reconfirmed a paraphyletic group.

Complete Mitochondrial Genomes

In this study, the whole mitochondrial genomes (mitogenomes) from four species were sequenced. The complete mitochondrial genomes of Sinopodisma pieli, S. houshana, S. qinlingensis, and S. wulingshanensis are 15,857 bp, 15,818 bp, 15,843 bp, and 15,872 bp in size, respectively. The 13 protein-coding genes (PCGs) begin with typical ATN codons, except for COXI in S. qinlingensis, which begins with ACC. The highest A+T content in all the sequenced orthopteran mitogenomes is 76.8% (S. qinlingensis), followed by 76.5% (S. wulingshanensis), 76.4% (S. pieli) and 76.4% (S. houshana) (measured on the major strand). The long polythymine stretches (T-stretch) in the A+T-rich region of the four species are not adjacent to the trnI locus but are inside the stem-loop sequences on the major strand. Moreover, several repeated elements are found in the A+T-rich region of the four species. Phylogenetic analysis based on 53 mitochondrial genomes using Bayesian Inference (BI) and Maximum Likelihood (ML) revealed that Melanoplinae (Podismini) was a monophyletic group; however, the monophyly of Sinopodisma was not supported. These data will provide important information for a better understanding of the phylogenetic relationship of Melanoplinae.

Complete Mitochondrial Genomes

The phylogenetic relationships between owls and nightjars are rather complex and controversial. To clarify these relationships, we determined the complete mitochondrial genomes of Glaucidium cuculoides, Otus scops, Glaucidium brodiei, Caprimulgus indicus, and Strix leptogrammica, and estimated phylogenetic trees based on the complete mitochondrial genomes and aligned sequences from closely related species that were obtained in GenBank. The complete mitochondrial genomes were 17392, 17317, 17549, 17536, and 16307 bp in length. All mitochondrial genomes contained 13 protein-coding genes, two rRNAs, 22 tRNAs, and a putative control region. All mitochondrial genomes except for that of Strix leptogrammica contained a pseudo-control region. ATG, GTG, and ATA are generally start codons, whereas TAA is the most frequent stop codon. All tRNAs in the new mtDNAs could be folded into canonical cloverleaf secondary structures except for tRNASer (AGY) and tRNALeu (CUN) , which missing the “DHU” arm. The phylogenetic relationships demonstrated that Strigiformes and Caprimulgiformes are independent orders, and Aegothelidae is a family within Caprimulgiformes. The results also revealed that Accipitriformes is an independent order, and Pandionidae and Sagittariidae are independent families. The results also supported that Apodiformes is polyphyletic, and hummingbirds (family Trochilidae) belong to Apodiformes. Piciformes was most distantly related to all other analyzed orders.

Abstract BackgroundAmong the Mangifera species, mango (Mangifera indica) is an important commercial fruit crop. However, very few studies have been conducted on the Mangifera mitochondrial genome. This study reports and compares the newly sequenced mitochondrial genomes of three Mangifera species. Results Mangifera mitochondrial genomes showed partial similarities in the overall size, genomic structure, and gene content. Specifically, the genomes are circular and contain about 63-69 predicted functional genes, including five ribosomal RNA (rRNA) genes and 24-27 transfer RNA (tRNA) genes. The GC contents of the Mangifera mitochondrial genomes are similar, ranging from 44.42–44.66%. Leucine (Leu) and serine (Ser) are the most frequently used, while tryptophan (Trp) and cysteine (Cys) are the least used amino acids among the protein-coding genes in Mangifera mitochondrial genomes. We also identified 7-10 large chloroplast genomic fragments in the mitochondrial genome, ranging from 1407-6142 bp. Additionally, four intact mitochondrial tRNAs genes (tRNA-Cys, tRNA-Trp, tRNA-Pro, and tRNA-Met) and intergenic spacer regions were identified. Phylogenetic analysis based on the common protein-coding genes of most branches provided a high support value. ConclusionsWe sequenced and compared the mitochondrial genomes of three Mangifera species. The results showed that the gene content of Mangifera mitochondrial genomes is similar across various species. Gene transferred from the chloroplast genome to the mitochondrial genome were identified. This study provides valuable information for evolutionary and molecular studies of Mangifera and a basis for further studies on genomic breeding of mango.

We determined the complete nucleotide sequence of the mitochondrial genome of Odorrana schmackeri (family Ranidae). The O. schmackeri mitogenome (18 302 bp) contained 13 protein-coding genes, 2 rRNA genes, 21 tRNA genes and a single control region (CR). In the new mitogenome, the distinctive feature is the loss of tRNA-His, which could be explained by a hypothesis of gene substitution. The new sequence data was used to assess the phylogenetic relationships among 23 ranid species mostly from China using maximum likelihood (ML) and Bayesian inference (BI). The phylogenetic analyses support two families (Ranidae, Dicroglossidae) for Chinese ranids. In Ranidae, we support the genus Amolops should be retained in the subfamily Raninae rather than in a distinct subfamily Amolopinae of its own. Meanwhile, the monophyly of the genus Odorrana was supported. Within Dicroglossidae, four tribes were well supported including Occidozygini, Dicroglossini, Limnonectini and Paini. More mitochondrial genomes and nuclear genes are required to decisively evaluate phylogenetic relationships of ranids.

Complete gene organizations of the mitochondrial genomes of three pulmonate gastropods, Euhadra herklotsi, Cepaea nemoralis and Albinaria coerulea, permit comparisons of their gene organizations. Euhadra and Cepaea are classified in the same superfamily, Helicoidea, yet they show several differences in the order of tRNA and protein coding genes. Albinaria is distantly related to the other two genera but shares the same gene order in one part of its mitochondrial genome with Euhadra and in another part with Cepaea. Despite their small size (14.1 – 14.5 kbp), these snail mtDNAs encode 13 protein genes, two rRNA genes and at least 22 tRNA genes. These genomes exhibit several unusual or unique features compared to other published metazoan mitochondrial genomes, including those of other molluscs. Several tRNAs predicted from the DNA sequences possess bizarre structures lacking either the T stem or the D stem, similar to the situation seen in nematode mt-tRNAs. The acceptor stems of many tRNAs show a considerable number of mismatched basepairs, indicating that the RNA editing process recently demonstrated in Euhadra is widespread in the pulmonate gastropods. Strong selection acting on mitochondrial genomes of these animals would have resulted in frequent occurrence of the mismatched basepairs in regions of overlapping genes.
