A complete mitochondrial genome of the large scaled tongue sole (cynoglossus macrolepidotus) from the east China sea

TL;DR

This paper reports the first complete mitochondrial genome of the large-scaled tongue sole, a fish species from China, and its genetic relationships with other related species.

Contribution

The study provides the first complete mitochondrial genome sequence for Cynoglossus macrolepidotus.

Findings

The mitochondrial genome is 16,647 base pairs long and includes 13 protein-coding genes, 22 tRNA genes, and two rRNA genes.

Phylogenetic analysis shows C. macrolepidotus is genetically closer to C. joyneri and C. puncticeps than to other Cynoglossus species.

The genome data will support future genetic and phylogenetic studies of the Cynoglossidae family.

Abstract

The Large-scaled tongue sole (Cynoglossus macrolepidotus, Bleeker, 1851) is an economically important fish species in China. This study presents the first complete mitochondrial genome of the Large-scaled tongue sole, with a total length of 16,647 base pairs. The genome includes 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, and two ribosomal RNA (rRNA) genes. Phylogenetic analysis reveals that C. macrolepidotus is genetically closer to Cynoglossus joyneri and Cynoglossus puncticeps than to other species within the Cynoglossus genus. This study provides valuable genetic data for future research on C. macrolepidotus and contributes to phylogenetic studies within the Cynoglossidae family.
