# Mitochondrial genome of Acheilognathus striatus characterisation and phylogenetic analysis

## TL;DR

This study analyzed the mitochondrial genome of Acheilognathus striatus to better understand its evolutionary relationships with other fish species.

## Contribution

The study provides the first complete mitochondrial genome sequence of Acheilognathus striatus and its phylogenetic placement.

## Key findings

- The mitogenome is 16,692 bp long and includes standard mitochondrial genes.
- A. striatus is phylogenetically closely related to R. shitaiensis.
- The mitogenome shows AT skewness and anti-G bias.

## Abstract

In this study, the taxonomic position of Acheilognathus striatus was clarified through mitogenome analysis. The circular mitogenome is 16,692 bp long and comprises 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and one non-coding D-loop region. The mitogenome exhibits AT skewness and anti-G bias. Phylogenetic trees were constructed using 22 Acheilognathinae species, with Gobioninae and Leuciscinae used as outgroups. The phylogenetic tree revealed that A. striatus formed a sister group with R. shitaiensis. This study contributes to a better understanding of the mitogenome characteristics and evolutionary relationships among Acheilognathinae species.
