The complete mitochondrial genome of dwarf danio, Danio nigrofasciatus.
In this study, we report the complete mitochondrial genome sequence of dwarf danio, Danio nigrofasciatus, for the first time. The genome is found to be 16 616 bp in length and has a base composition of A (31.97%), G (15.88%), C (23.99%), and T (28.16%), indicating that the percentage of A + T (60.13%) was higher than G + C (39.87%). The mitochondrial genome contains a typically conserved structure including 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNA), 2 ribosomal RNA genes (rRNA), and 1 control region (D-loop). Most of the genes were located on the H-strand except for the ND6 gene and 8 tRNA genes. To obtain a more complete understanding of the evolutionary history between the dwarf danio and other species, 11 mitochondrial genomes were used for phylogenetic analysis. This mitochondrial sequence reported here would be useful to uncover the D. nigrofasciatus evolution and add a new genetic resource for the genus Danio.
