Abstract

Dojo loach Misgurnus anguillicaudatus, a small-sized freshwater fish species, is not only one of the most important cultured fish in East Asia, but also a promising model animal to study evolutionary biology for polyploidy. We sequenced the complete mitochondrial genomes from the natural diploid and tetraploid individuals of this species. The two different cytotypes loaches share the same length (16,646 bp) and structural organization of mitochondrial genome. The two genomes have 98.3% nucleotide sequence similarity, and the biggest nucleotide sequence divergence between homologous genes is observed in CYTB gene.
