The complete mitochondrial genome of an endangered triton snail Charonia lampas (Littorinimorpha: Charoniidae) from South Korea.

ABSTRACT: The complete mitochondrial genome of an endangered triton snail Charonia lampas (Littorinimorpha: Charoniidae) from South Korea was determined with the size of 15,330 bp, which contained 13 protein-coding genes, 22 tRNAs, and two rRNAs. The overall features of the mitochondrial genome are similar to those of typical gastropod mitochondrial genomes, except for the absence of a control region (CR): a conserved gene order, a high A + T content (67.45% for C. lampas), preference for AT-rich codons, etc. It is the second mitochondrial genome reported from this species after Cho et al. (2017), and there is ca. 98% sequence similarity between those of the species. According to the maximum-likelihood tree, C. lampas placed within the monophyletic Tonnoidea, forming a monoclade with Cypraeoidea and Stromboidea within Littorinimorpha. Interestingly, we confirmed that Vermetoidea is placed at the basal position of the monophyletic Littorinimorpha.

The mitochondrial genome of an Endangered freshwater snail Koreoleptoxis nodifila (Caenogastropoda: Semisulcospiridae) from South Korea.

Project description:The mitochondrial genome of the Endangered freshwater snail Koreoleptoxis nodifila (Caenogastropoda: Semisulcospiridae) from South Korea is determined and characterized in detail. It is 15,737 bp in length being composed of 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs), and one control region. It has a base composition of 31.23% for A, 16.29% for G, 17.84% for C, and 34.64% for T. The phylogenetic trees reconstructed based on the maximum-likelihood (ML) method and Bayesian inference (BI) confirmed that K. nodifila belongs to the Semisulcospiridae clade in the monophyletic caeonogastropod superfamily Cerithioidea.

Full-length mitochondrial genome of the triton trumpet Charonia lampas (Littorinimorpha: Ranellidae).

Project description:The full-length mitochondrial genome of the triton trumpet Charonia lampas (Linnaeus, 1758) was analyzed by the primer walking method. Its mitogenome is 15,382?bp in length, comprising 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes. The gene order of C. lampas is congruent with those previously reported for the infraorder Littorinimorpha. This is the first full-length mitogenome sequence for the genus Charonia. In the phylogenetic tree, C. lampas formed a monophyletic group with the other species of the superfamily Tonnoidea, but did not show the closest phylogenetic relationship to a species from the same family, Ranellidae.

Complete mitochondrial genome and phylogenetic analysis of Callorhinus ursinus: an endangered species from South Korea.

Project description:We present the complete mitochondrial genome and a phylogenetic analysis of Callorhinus ursinus, the northern fur seal, determined using Illumina next-generation sequencing (NGS) technology. The total length of the mitogenome was 17,154 bp, which consisted of 13 protein-coding genes, two ribosomal RNA genes, 22 tRNA genes, and one control region. The base composition of the entire mitogenome was 33.5% (A), 26.3% (C), 13.9% (G), and 26.3% (T) with an A + T bias of 59.8%. The control region contained two types of tandem repeats. A neighbour-joining (NJ) tree was constructed and comprised two clades with C. ursinus forming a monophyletic group. Data produced in this study will aid exploration of the genetic diversity of endangered C. ursinus and contribute to molecular identification of this species.

The complete mitochondrial genome of Glossaulax reiniana (Littorinimorpha: Naticidae).

Project description:In the present study, the complete mitochondrial genome of Glossaulax reiniana was determined using the next-generation sequencing. The circular genome was found to be 15,254?bp in length and had an overall nucleotide composition of 30.6% A, 14.1% C, 15.8% G, and 39.5% T. Similar to the typical caenogastropod mitochondrial genomes, it contained 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and a potential control origin. All protein-coding genes started with standard initiation codons (ATA and ATG) and ended by TAA or TAG. The lengths of 12S ribosomal RNA and 16S ribosomal RNA were 948 and 1353?bp, respectively. The largest noncoding region considered to contain the origin of replication was 59?bp in length. The complete mitochondrial genome reported here would provide useful information for molecular phylogeny, genetic conservation, and sustainable management of G. reiniana.

Complete mitochondrial genome of the Endangered species Ellobium chinense (Pulmonata, Ellobiidae) from Korea.

Project description:The complete mitochondrial genome of Ellobium chinense (Ellobioidea, Ellobiidae), an Endangered species in South Korea, is reported here for the first time. The mitogenome of E. chinense is 13,979 base pairs in total length and includes 13 PCGs, small and large rRNAs, and 21 tRNAs. Twelve genes are encoded on the light-strand and 24 genes on the heavy-strand. Compared to four other ellobiid species, the PCGs of E. chinense have a conserved gene order except for the positions of ND4L and ND4. These data provide useful molecular information for phylogenetic studies concerning ellobiids and related species.

The complete mitochondrial genome and phylogenetic position of the Endangered red-spotted grouper Epinephelus akaara (Perciformes, Serranidae) collected in South Korea.

Project description:We determined complete nucleotide sequences of the mitochondrial genome of two individuals of the Red-spotted grouper, Epinephelus akaara (Perciformes, Serranidae), caught in South Korea. The mitochondrial genome had 16,795 base pairs (bp) and 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs, and a noncoding control region. The two mt genomes were highly homologous (99.71% similarity). The two mt genomes of E. akaara analyzed in this study were found in Clade I with those of E. awoara, E. fasciatomaculosus, E. sexfasciatus, E. diacanthus, E. sticus, and E. morio. Here, we reported the complete mt genome sequence of E. akaara, suggesting that this may use in phylogenetic studies of Epinephelus.
