Characterization of the complete mitochondrial genome and phylogenetic analysis of (Cypriniformes, Danionidae, Chedrinae).

This study aimed to sequence and annotate the complete mitochondrial DNA genome sequence of Complete mitochondrial genome is a circular molecule of 16,552 bp in length, including 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and a displacement loop region. Proportion of nucleotides in mitochondrial genome is 26.8% T, 26.9% C, 27.6% A, and 18.8% G, with an AT bias of 54.4%. Maximum-likelihood phylogenetic tree was reconstructed using the connected protein sequences of 13 PCGs of and other 18 fishes. Result of phylogenetic analysis supports a close relationship between and (Hamilton, 1807). Fundamental genetic data of would be beneficial for further studies on genetic diversity and phylogeny.
