Three mitochondrial genomes of freshwater fishes in the genus Squalidus (Cypriniformes: Gobionidae).

ABSTRACT: Mitochondrial genomes of Squalidus mantschuricus, S. chankaensis, and S. longifilis have been determined using Sanger sequencing (GenBank Accession No. MT767745-MT767747). The three mitochondrial genomes consist of 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and one control region with the length of 16,605, 16,611, and 16,607 bp. Phylogenetic analysis of the three species showed that S. mantschuricus is nested within a fully supported terminal clade with S. argentatus, and S. chankaensis is a sister group of S. mantschuricus, S. argentatus, and S. wolterstorffi. Squalidus longifilis is positioned in a clade with S. multimaculatus and S. gracilis.

Three complete mitochondrial genomes of freshwater fishes in the genus Abbottina (Cypriniformes: Gobionidae).

Project description:Abbottina binhi has been misidentified as Abbottina rivularis in China for a long time. In this study, we determined three mitochondrial genomes of A. rivularis and A. binhi such that these data should contribute to molecular identifications of the two species. The size of new mitochondrial genomes was 16,609 or 16,599?bp with A?+?T bias of 55.7-56.5% in the base compositions. Our reconstructed phylogeny showed that A. rivularis and A. binhi formed a sister taxon relationship, and they together were a monophyletic group.

Two complete mitochondrial genomes of Paraleucogobio fishes (Cypriniformes: Gobionidae).

Project description:Freshwater fishes in the genus Paraleucogobio include two species, Paraleucogobio notacanthus and Paraleucogobio strigatus. In this study, we determined complete mitochondrial genomes of P. notacanthus and P. strigatus to clarify their phylogenetic positions. The two mitochondrial genomes showed similar gene arrangements, codon use, gene overlaps or gene intervals with the length of 16,596?bp and 16,598?bp. Our phylogeny revealed that P. notacanthus and P. strigatus were nested within Gnathopogon fishes. The findings indicate that Paraleucogobio is a junior synonym of Gnathopogon.

Phylogeographical Analysis of the Freshwater Gudgeon Huigobio chenhsienensis (Cypriniformes: Gobionidae) in Southern China.

Project description:The freshwater gudgeon Huigobio chenhsienensis (Cypriniformes: Gobionidae) is a small fish endemic to southern China. In this study, we used mitochondrial cytochrome b gene (Cytb), from wide-ranging samplings of H. chenhsienensis from the Ou River (the central of southern China) to the Yangtze River Basin (the northernmost part of southern China) to explore genetic variations and the evolutionary history of H. chenhsienensis in southern China. In total, 66 haplotypes were identified from Cytb sequences of 142 H. chenhsienensis individuals, which could be divided into lineages A, B, and C with divergence times of ~4.24 Ma and ~3.03 Ma. Lineage A was distributed in the lower reaches of the Yangtze River, the Oujiang River, and the Jiao River, lineage B was distributed in the Qiantang River and the Cao'e River, whereas lineage C was restricted to the Poyang Lake drainage from the middle reaches of the Yangtze River. Lineage A could be subdivided into sub-lineages A-I, A-II, A-III, and A-IV, with divergence times of 1.30, 0.97, and 0.44 Ma. Lineage C could be subdivided into sub-lineages C-I and C-II, with a divergence time of 0.85 Ma. Our findings indicate that climate change during the Pliocene and Pleistocene eras, as well as the limited dispersal ability of H. chenhsienensis, have been major drivers for shaping the phylogeographical patterns of H. chenhsienensis.

Complete Mitochondrial Genomes of Baikal Oilfishes (Perciformes: Cottoidei), Earth's Deepest-Swimming Freshwater Fishes.

Project description:Sculpins are predominantly benthic sit-and-wait predators that inhabit marine and freshwaters of the Northern Hemisphere. In striking contrast to riverine relatives, sculpins endemic to Lake Baikal have diversified in both form and function, with multiple taxa having adaptations for pelagic and bathyal niches within the world's deepest lake. Baikal Oilfishes (Comephorus spp.) represent a highly apomorphic taxon with unique skeletal morphology, soft anatomy, and reproductive ecology. Selection for novel behavior and life history may be evident in genes responsible for organismal energy balance, including those encoding subunits of the electron transport chain. Complete mitochondrial genomes were sequenced for the Big Baikal Oilfish (Comephorus baicalensis) and Little Baikal Oilfish (Comephorus dybowskii). Mitochondrial genomes encode genes essential for electron transport, and data provided here will complement ongoing investigations of genome-to-phenome maps for teleost respiration and metabolism. Phylogenetic analyses including oilfish mitogenomes and all publicly available cottoid representative sequences are largely concordant with previous studies.

The complete mitochondrial genomes of two Chinese endemic cave fishes, Sinocyclocheilus longibarbarus and Sinocyclocheilus punctatus (Cypriniformes: Cyprinidae).

Project description:Sinocyclocheilus longibarbarus and Sinocyclocheilus punctatus were collected from a karst cave Libo County, southwest of China. The two Sinocyclocheilus species can be distinguished obviously by external morphological characteristics. In this study, the complete mitochondrial genome sequences of two species were assembled, and both sequences reflected gene organization typical for mitochondrial DNA of the genus Sinocyclocheilus, comprising of 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (rRNAs), and a large non-coding control region. Phylogenetic analysis showed that S. punctatus was first clustered together with S. mutipunctatus, and S. longibarbarus was closely related to S. yishanensis. The complete mitogenome of two species may provide useful information for the further taxonomic and phylogenetic studies.
