Complete mitochondrial genome of Yangtze River wild common carp (Cyprinus carpio haematopterus) and Russian scattered scale mirror carp (Cyprinus carpio carpio)

AbstractWe sequenced the complete mitogenomes of (Cyprinus carpio haematopterus) and Russian scattered scale mirror carp (Cyprinus carpio carpio). Comparison of these two mitogenomes revealed that the mitogenomes of these two common carp strains were remarkably similar in genome length, gene order and content, and AT content. There were only 55 bp variations in 16,581 nucleotides. About 1 bp variation was located in rRNAs, 2 bp in tRNAs, 9 bp in the control region and 43 bp in protein-coding genes. Furthermore, forty-three variable nucleotides in the protein-coding genes of the two strains led to four variable amino acids, which were located in the ND2, ATPase 6, ND5 and ND6 genes, respectively.
