The complete mitochondrial genome of the freshwater fish Traccatichthys pulcher (Cypriniformes: Nemacheilidae) from China.

ABSTRACT: This study aimed to sequence and annotate the complete mitochondrial DNA genome sequence of Traccatichthys pulcher. The mitochondrial genome comprised 16,583 bp, harboring 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and a control region. The whole genome contained T (25.8%), C (26.9%), A (31.4%), and G (15.9%), showing an obvious AT bias (57.2%). Based on the concatenated protein sequences of 13 PCGs, a phylogenetic tree was reconstructed by the maximum likelihood method, and the topology revealed the monophyly of Traccatichthys, and the gathering of T. pulcher and M. pulcher. The mitochondrial DNA of T. pulcher (MZ853162.1) and M. pulcher (NC_031581.1) were aligned by the BLAST 2 sequences tool, which showed 97% similarity.
