Abstract

The complete mitochondrial genome of the sun loach (Yasuhikotakia eos) was determined based on Illumina data in this study. The result showed that the closed double-stranded circular mitogenome was 16,738 bp in total length (GenBank accession number: MT800510) with 58.41% AT. The mitochondrial DNA consisted of 13 protein-coding genes (PGCs), 22 transfer RNA (tRNA) genes, 2 ribosomal (rRNA) genes, and 1 non-coding control region. Phylogenetic analysis suggested that Y. eos was most closely related to its congener Y. modesta. This work provides molecular information for further research on species identification and evolutionary relationships.
