Characterization of the complete mitochondrial genome of demersal flatfish Eopsetta grigorjewi (Pleuronectiformes: Pleuronectidae) from South Korea

Eopsetta grigorjewi (Pleuronectiformes: Pleuronectidae) is a demersal flatfish found in South Korea, Japan, Taiwan, China, and the Yellow Sea. E. grigorjewi complete mitochondrion DNA (mtDNA) consists of 16,921 bp and a 54% A + T content. It includes 2 ribosomal RNA (rRNA), 22 transfer RNA (tRNA), 13 protein-coding genes, and 1 non-coding regulatory area. ND2, ND3, ND4, COII, COIII, ATPase6, and CytB all have incomplete stop codon genes. The evolutionary analysis of 13 species from the same family indicated a close relationship. This work will be valuable for future research on molecular evolution and the creation of biomarker databases for determining the originality of E. grigorjewi.

Automated summary

This study investigated the mitochondrial DNA composition and gene coding of Eopsetta grigorjewi, as well as conducted evolutionary analysis to reveal its close relationship with other species from the same family. The findings are valuable for future research on molecular evolution and the creation of biomarker databases.
