Flatfishes (Pleuronectiformes) exhibit different types of large-scale gene rearrangements. In the present study, the mitochondrial (mt) genome (18,369bp) of a tonguefish, Cynoglossus trigrammus, was determined using de novo mitochondrion genome sequencing. Compared with other flatfishes, the mt genome of C. trigrammus revealed distinct mitogenome architectures that primarily included two striking findings: 1) insertion of an additional long non-coding region (1647bp) making it the second… 
Novel gene rearrangement pattern in Cynoglossus melampetalus mitochondrial genome: New gene order in genus Cynoglossus (Pleuronectiformes: Cynoglossidae).
This is the first report of two different patterns of mitogenomic gene-arrangement within the same genus in teleost, and the reduced trend of the intergenic gap between Q and I suggests that the event of gene rearrangement can be traced back to early Cynoglossinae differentiation.
Characterization of the complete mitochondrial genome of Cynoglossus gracilis and a comparative analysis with other Cynoglossinae fishes.
This study provides important mitogenomic data for analyzing phylogenetic relationships in the Cynoglossinae and detects rearrangement of genes in C. gracilis, including a control region translocation, tRNA(Gln) gene inversion, and tRNA-Ile gene shuffling.
Novel Gene Rearrangement and the Complete Mitochondrial Genome of Cynoglossus monopus: Insights into the Envolution of the Family Cynoglossidae (Pleuronectiformes)
The results support the idea that Cynoglossidae is a monophyletic group and indicate that C. monopus has the closest phylogenetic relationship with C. puncticeps, and the time-calibrated evolutionary trees were reconstructed.
Structure, evolution and phylogenetic informativeness of eelpouts (Cottoidei: Zoarcales) mitochondrial control region sequences
A comparative phylogenetic and structural analysis of 29 CR sequences belonging to the long shanny Stichaeus grigorjewi together with nine sequences of other eelpouts taxa representing four families in contrast to mitochondrial protein-coding fragments finds a hidden CR variation constrains on the landscape level and a lack of nucleotide saturation.
Characterization of the mitogenome of Cynoglossus Senegalensis (Pleuronectiformes: Cynoglossidae)
Phylogenetic analysis showed that C. senegalensis is most closely related to C. sinicus and S.bilineatus, which supports the previous result that genus Cynoglossidae is evolutionary paraphyletic.
Satellite DNA evolution: old ideas, new approaches.
Advances in computational tools and sequencing technologies now enable identification and quantification of satellite sequences genome-wide and how their applications are furthering knowledge of satellite evolution and function is described.


A novel rearrangement in the mitochondrial genome of tongue sole, Cynoglossus semilaevis: control region translocation and a tRNA gene inversion.
A novel rearrangement in the mitogenome of Cynoglossus semilaevis is reported, with a striking finding that the tRNA(Gln) gene is translocated from the light to the heavy strand (Q inversion) and accompanied by shuffling of the t RNA(Ile) gene and long-range translocation of the putative control region downstream to a site between ND1 and the tRNAs.
Organization of the mitochondrial genome of Odontobutis sinensis (Perciformes: Odontobutidae): rearrangement of tRNAs and additional non-coding regions
The molecular data presented could play a useful role to study the evolutionary relationships and population genetics of the Odontobutidae and some typical conserved domains were identified.
Unusual mitochondrial genome structure of the freshwater goby Odontobutis platycephala: rearrangement of tRNAs and an additional non‐coding region
Phylogenetic analysis performed using the cytochrome b gene sequences of 16 Korean freshwater fishes with the Bayesian algorithm showed that O. platycephala forms a clade (1·00 of posterior probability) with other species of Odontobutis, suggesting that the observed rearrangement between the ND4 and ND5 genes in the O. PlatycePHala mitogenome reflects independent events.
A novel model of double replications and random loss accounts for rearrangements in the Mitogenome of Samariscus latus (Teleostei: Pleuronectiformes)
A “Double Replications and Random Loss” model is proposed to explain the rearrangement events in S. latus mitogenome and it is proposed that one of each pair of duplicated genes was lost in a random event.
Characterization of the Macropodus opercularis complete mitochondrial genome and family Channidae taxonomy using Illumina-based de novo transcriptome sequencing.
The complete mitochondrial genome of M. opercularis was sequenced using Illumina-based de novo transcriptome technology and annotated using bioinformatic tools and supported the inclusion of family Channidae in suborder Channoidei.
A comprehensive description and evolutionary analysis of 9 Loliginidae mitochondrial genomes
The results showed that Loliginidae is divided into two major lineages, with S. lessoniana sister to a clade comprising the remaining species, and the level of selective pressures imposed on different protein-coding genes was analyzed.
Complete Mitochondrial DNA Sequences of the Threadfin Cichlid (Petrochromis trewavasae) and the Blunthead Cichlid (Tropheus moorii) and Patterns of Mitochondrial Genome Evolution in Cichlid Fishes
The first results of the assembly and annotation process for two closely related but eco-morphologically highly distinct Lake Tanganyika cichlids, Petrochromis trewavasae and Tropheus moorii are presented, confirming that the two species are very closely related with an overall sequence similarity of 96%.
The mitochondrial genome of the lizard Calotes versicolor and a novel gene inversion in South Asian draconine agamids.
It is hypothesize that inversion of the trnP gene was originally mediated by a homologous DNA recombination and that the de novo gene organization that does not disrupt expression of mitochondrial genes has been maintained in draconine mtDNAs for such a long period of time.
A Comprehensive Description and Evolutionary Analysis of 22 Grouper (Perciformes, Epinephelidae) Mitochondrial Genomes with Emphasis on Two Novel Genome Organizations
Groupers of the family Epinephelidae are a diverse and economically valuable group of reef fishes and characterized and compared these genomes among 22 species, 17 newly sequenced, providing further support for the elevation of the subfamily EpinePhelinae to familyEpinep Helidae, the resurrection of the genus Hyporthodus, and the combination of the monotypic genera Anyperodon and Cromileptes to genus Epine phelus.
Mitogenomic evidence for the monophyly of elopomorph fishes (Teleostei) and the evolutionary origin of the leptocephalus larva.
Mitogenomic data strongly supported the monophyly of Elopomorpha, indicating the validity of the leptocephalus as an elopomorph synapomorphy and the order Elopiformes occupied the most basal position in the elopomorphic phylogeny.
