The study on the complete mitochondrial genome of Acanthopsetta nadeshnyi and its phylogenetic position.

Pleuronectidae is a well-studied familyin the order Pleuronectiformes. In contrast, genetic research on the flatfish Acanthopsetta nadeshnyi of the Pleuronectidae family is limited. This study reports the complete mitogenome of A. nadeshnyi. The mitogenome was 17,206 bases long and included 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a putative control region. Phylogenetic analysis based on the nucleotide sequences of the 13 PCGs confirmed that A. nadeshnyi belongs to the Pleuronectidae family.

Characteristics and phylogenetic analysis of the complete mitochondrial genome of Microstomus achne.

Microstomus achne (Jordan and Starks, 1904) is an economically valuable flatfish belonging to the family Pleuronectidae and the only flatfish that inhabits Korea. Here, we report on the complete mitochondrial genome of M. achne and the phylogenetic relationship between close species. The mitogenome is 16,971 bp long and encodes 13 protein-coding genes (PCGs), 22 transfer RNAs, and two ribosomal RNAs. The phylogenetic analysis showed that M. achne clustered with Glyptocephalus stelleri, which supports the conclusion that M. achne belongs to the family Pleuronectidae. The results of this study provide a better understanding of M. achne.

Characterization and phylogenetic analysis of the complete mitochondrial genome of Notostomum cyclostomum.

Notostomum cyclostomum is a parasite that lays eggs on the snow crab shells and causes various diseases by parasitizing fish. Although there have been some studies on the life history of this parasite and the associated fish diseases, little is known about the molecular biology of this parasite. Thus, here we report the mitochondrial genome of N. cyclostomum, which is 16,972 bp long and contains 13 mitochondrial protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a putative control region with a 92% AT-rich sequences between tRNA-R and tRNA-H. Phylogenetic analysis using 13 PCGs confirmed that N. cyclostoum belongs to the family Pisciodlidae. This is the first study revealing the complete mitochondrial genome sequence of N. cyclostomum.

The complete mitochondrial genome of Pseudopleuronectes herzensteini.

Pseudopleuronectes herzensteini belonging to Pleuronectiformes (family Pleuronectidae) is important in the fishery industry. However, the molecular biology of this valuable fish has hardly been reported. Thus, here we report the complete mitochondrial genome of P. herzensteini. The mitochondrial DNA (mtDNA) of P. herzensteini is 16,719 bp long and contains 13 mitochondrial protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a putative control region between tRNA-P and tRNA-F distinguished by a single short noncoding region. Phylogenetic analysis using PCGs confirmed that this mtDNA sequence belongs to the family Pleuronectidae. This is the first study reporting the complete mitochondrial genome sequence of P. herzensteini.
