Abstract
The Swan goose Anser cygnoides is a large threatened goose species in the IUCN Red List, with a natural breeding range in East Asia, migratory and wintering mainly in central and eastern China. In this study, we used PCR-based method to determine the complete mitochondrial genome (mtDNA) of this Anatidae species. The complete mtDNA is a 16,740 bp circular molecule containing 37 typical genes. The gene order is identical with that of the standard avian gene order. All protein-coding genes start with a typical ATG codon except ND5, COI and COII. The termination codon is usually the standard TAA. The non-coding region contains some inter-genic spacers and a control region.
