title: Complete mitochondrial genome of the Bewick's swan Cygnus columbianus bewickii (Aves, Anseriformes, Anatidae).
abstract: The mitochondrial genome of Bewick's swan Cygnus columbianus bewickii was completely sequenced and then the resultant data were compared with those of the whistling swan Cygnus columbianus columbianus. The complete mitochondrial genome sequence of C. c. bewickii was 16,727 bp in length and its gene arrangement pattern, gene content, and genome organization were identical to those of Cygnus species. The similarities of nucleotide and amino acid sequences between the two swans were 99.1% and 99.6%, respectively. Out of the 13 protein-coding genes and 2 rRNA genes, COIII showed the lowest nucleotide sequence similarity with 98.0%. On the other hand, in amino acid sequence similarities, both COII and ATP6 showed the lowest with 98.7% in common. The control region has the 97.8% nucleotide sequence similarity.
