Although the fugu Takifugu rubripes has attracted attention as a model organism for genomic studies because of its compact genome, it is not generally appreciated that there are approximately 25 closely related species with limited distributions in the waters of East Asia. We performed molecular phylogenetic analyses and constructed a time tree using whole mitochondrial genome sequences from 15 Takifugu species together with 10 outgroups to examine patterns of diversification. The resultant… Expand
Capacity for freshwater acclimation and differences in the transcription of ion transporter genes underlying different migratory life histories of Takifugu fish.
TLDR
Different ion transporter expression patterns between the five Takifugu species indicate that the transcriptional regulation of cftr in the gill and ncc in the intestine may be important for the improvement of hypotonic acclimation capacity and evolution of anadromy in the Tak ifugu species. Expand
The mitogenomic contributions to molecular phylogenetics and evolution of fishes: a 15-year retrospect
TLDR
It is argued that intensive taxonomic sampling from an interface between species and populations together with the massive character sampling from mitogenome sequences using next-generation sequencing (NGS) technologies would enable simultaneous attempts to delimit species boundaries and to reconstruct evolutionary relationships at much finer scale, eventually unraveling the fish part of the Tree of Life in a bottom-up manner with more accurate estimations of species diversity.

The Genetic Basis of Scale-Loss Phenotype in the Rapid Radiation of Takifugu Fishes
TLDR
The results suggest that the convergence of the scale-loss phenotype may be constrained by signaling modules with conserved roles in scale development, and Fgfr1a1, another memebr of the Fgf signaling pathway, has been implicated in scale loss/scale shape in fish distantly related to Takifugu. Expand
Asymmetric hybridization and introgression between sibling species of the pufferfish Takifugu that have undergone explosive speciation
TLDR
Results suggest that interspecific gene flow has been highly asymmetrical toward T. snyderi, which may partly explain the marked difference in intraspecific genetic diversity between the two species, indicating the need for continuous monitoring of hybridization and its impact on integrity of each parental species under the changing marine environment.

Population genetic structure of the grass puffer (Tetraodontiformes: Tetraodontidae) in the northwestern Pacific revealed by mitochondrial DNA sequences and microsatellite loci
TLDR
In an attempt to review the taxonomic status of grass puffer at a molecular level, 209 individuals from nine localities in the northwestern Pacific were analyzed using mitochondrial DNA and microsatellites and suggested that T. niphobles is a distinct species differing from T. alboplumbeus. Expand
Fugu: A Compact Model Vertebrate Genome
The genome of the Japanese pufferfish, Takifugu rubripes (fugu), which is among the smallest vertebrate genomes, is an attractive model vertebrate genome and was the first vertebrate genome to beExpand
Adaptive evolution of low-salinity tolerance and hypoosmotic regulation in a euryhaline teleost, Takifugu obscurus
TLDR
This study identified hundreds of genes under selection related to hypoosmotic regulation between T. obscurus and other Takifugu species, including 16 representative genes involving ion transporters, genes involved in hormone regulation, and a gene associated with water absorption. Expand
Molecular phylogenetic relationship of Tetraodon pufferfish based on mitochondrial DNA analysis
TLDR
The obtained phylogenetic tree classified Tetraodon species into three groups, correlating well with their habitats, such as Asian freshwater, Asian brackish water, and African freshwater, suggesting that the speciation of Tetraodontid species in the Asian freshwater group was caused by the molecular evolution associated with osmotic regulation. Expand
Multiple Invasions into Freshwater by Pufferfishes (Teleostei: Tetraodontidae): A Mitogenomic Perspective
TLDR
Relaxed molecular-clock Bayesian divergence time estimation suggests that the timing of these invasions differs between continents, occurring at 0–10 million years ago in South America, 17–38 MA in Central Africa, and 48–78 MA in Southeast Asia, which could facilitate adaptation to freshwater habitats in each continent. Expand
The first mitogenome of the Nile pufferfish Tetraodon lineatus from Lake Turkana in East Africa: new insights into the genus
TLDR
Mitogenomic comparison and phylogenetic analysis supported not only the morphology-based recognition of the puffer fish specimen from Lake Turkana as the Nile pufferfish, but also the identification of the Chinese specimen recently recorded as T. lineatus and its African source. Expand

Molecular phylogeny and evolution of the freshwater eels genus Anguilla based on the whole mitochondrial genome sequences.
TLDR
The present study clearly indicated a sister relationship between the Atlantic and Oceanian species, which now have distantly separated geographic distributions, and suggest that the hypotheses for the dispersal route and divergence time of the genus Anguilla should be reconsidered. Expand
Takifugu obscurus is a euryhaline fugu species very close to Takifugu rubripes and suitable for studying osmoregulation
TLDR
"mefugu", which has drawn little attention from animal physiologists until this study, is a useful model animal for studying the molecular mechanism of maintaining body fluid homeostasis and its genomic sequence shares a very high homology with those of the other Takifugu species such that the existing TakIfugu genomic information resources can be utilized. Expand
Mitogenomic exploration of higher teleostean phylogenies: a case study for moderate-scale evolutionary genomics with 38 newly determined complete mitochondrial DNA sequences.
TLDR
It is concluded that purposeful higher-density taxonomic sampling, subsequent sequencing efforts, and phylogenetic analyses of their mitogenomes may be decisive in resolving persistent controversies over higher-level relationships of teleosts, the most diversified group of all vertebrates, comprising over 23,500 extant species. Expand
Tetraodon fluviatilis, a new puffer fish model for genome studies.
TLDR
A T. fluviatilis cDNA library is constructed and characterized to facilitate and extend the use of the puffer fish as a model for genome studies, and phylogenetic analysis placed both fishes at the base of the Perciformes lineage. Expand
Major patterns of higher teleostean phylogenies: a new perspective based on 100 complete mitochondrial DNA sequences.
TLDR
Many unexpected, but highly supported relationships were found within the Percomorpha, being highly promising for the next investigative step towards resolution of this remarkably diversified group of teleosts. Expand
The medaka draft genome and insights into vertebrate genome evolution
TLDR
A high-quality draft genome sequence of a small egg-laying freshwater teleost, medaka, revealed that eight major interchromosomal rearrangements took place in a remarkably short period of ∼50 Myr after the whole-genome duplication event in the teleost ancestor and afterwards, intriguingly, the medaka genome preserved its ancestral karyotype for more than 300‬Myr.

The cost of DNA sequencing continues to fall, which makes it feasible to develop genomic resources for new model species that are well suited for studying questions in evolutionary biology. TheExpand
A new perspective on phylogeny and evolution of tetraodontiform fishes (Pisces: Acanthopterygii) based on whole mitochondrial genome sequences: Basal ecological diversification?
TLDR
It is likely that the basal split had involved ecological diversification, because most members of Tetraodontoidei exclusively occur in shallow waters, while those of Triacanthodoidei occur mainly in relatively deep waters along continental shelves and slopes except for more derived ostraciids. Expand
Mitogenomic evaluation of the historical biogeography of cichlids toward reliable dating of teleostean divergences
TLDR
It is proposed to add the biogeographic assumption of cichlid divergences by continental fragmentation as effective time constraints in dating teleostean divergence times to achieve a considerable reduction in credibility intervals in the estimated divergence times. Expand
Basal actinopterygian relationships: a mitogenomic perspective on the phylogeny of the "ancient fish".
TLDR
Mitogenomic data strongly supported not only the monophyly of the teleosts (osteoglossomorphs and above), but also a sister-group relationship between theteleosts and a clade comprising the acipenseriforms, lepisosteids, and Amia, with the polypteriforms occupying the most basal position in the actinopterygian phylogeny.
