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

ABSTRACT: 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 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.

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 mitochondrial genome of Milvus migrans (Aves, Accipitriformes, Accipitridae), an endangered species from South Korea.

Project description:The complete mitochondrial genome sequence of black kite, Milvus migrans, one of the most common diurnal raptor, was characterized using next generation sequencing. The whole genome size was 18,016?bp and consisted of 13 protein-coding genes, 22 tRNAs, 2 rRNAs, a putative control region (CR), and a second control region (pseudo-CR). A frameshift mutation was found in the ND3 gene. Phylogenetic analysis illustrated monophyly of the subfamily Melieraxinae with high statistical support. The genetic resource obtained here will help to resolve taxonomic issues related to subspecies of M. migrans and will act as a starting point for conservation genetics.

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

Project description: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.

Complete mitochondrial genome of Callipogon relictus Semenov (Coleoptera: Cerambycidae): a natural monument and endangered species in Korea.

Project description:In the present study, we report the first complete mitochondrial DNA genome of the genus Callipogon based on C. relictus, a natural monument and endangered species in South Korea. The mitogenome is 15,742 base pairs with 13 protein coding genes (PCGs), two rRNAs, 22 tRNAs, and a 1033?bp long AT-rich region. The overall base composition was 67.3% AT and 32.7 GC. Among 13 PCGs, seven genes (Nad2, Atp8, Atp6, Nad4L, Nad6, Cob, Nad1) harbour the typical stop codon TAA or TAG, whereas remaining five genes terminate with T. Interestingly, Cox3 employs AGA as the termination codon.

Project description:The complete mitochondrial genome of Muskrat, Ondatra zibethicus (Rodentia: Cricetidae) in Korea was sequenced for the first time using the next-generation sequencing method to understand its evolutionary relationship and to be helpful to establish a management plan. This mitogenome was 16,350 base pairs in length, containing 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and one control region. Its overall A, C, G, and T contents were 32.0%, 26.9%, 12.6%, and 28.5%, respectively. A + T content (63.7%) was higher than G + C content (36.3%). We made the phylogenetic tree of muskrat and other 12 species of order Rodentia distributed in Korea.

The overall base composition of the complete genome is A (29.57%), T (28.08%), G (16.54%), and C (25.80%), with a high A + T content of 57.65%. Phylogenetic analysis showed that K. brevifasciata was most closely related to K. multifasciatas.

Complete mitochondrial genome of endangered Rhodeus pseudosericeus and its implications for the reconstruction of phylogenetic relationship among Acheilognathinae species.

Project description:Rhodeus pseudosericeus is a native bitterling to the Korean Peninsula and found in very limited areas with small census size. Here, its complete mitochondrial genome was analyzed to provide novel data for the reconstruction of phylogenetic relationship among Acheilognathinae species. The genome was a 16,574?bp long consisting of 1 putative control region, 2 rRNA genes, 22 tRNA and 13 protein-coding genes. The gene arrangement was completely identical to those observed in other Acheilognathinae species as well as in other cyprinid species. In our phylogenetic analyses, three major genera of Acheilognathinae indepedently formed monophyletic groups in the tree reconstructed based on the whole genome sequences, whereas Rhodeus was not recovered as a single monophyly when solely considering protein-coding genes, indicating that the taxonomic reevaluation is still required in this subfamily.
