Sequence and gene organization of the Xilin small partridge duck ( Anseriformes, Anatidae, Anas ) mitochondrial DNA.

The complete mitochondrial genome sequence of the Xilin small partridge duck was measured by PCR-based methods. Our research findings revealed that the entire mitochondrial genome of the Xilin small partridge duck was 16,604 bp (GenBank accession number: KJ833586). The contents of A, T, C, and G in the mitochondrial genome were 29.20%, 22.19%, 32.82% and 15.79%, respectively, which were similar to the majority of most avian species. The complete mitochondrial genome of the Xilin small partridge duck contains 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and 1 control region. Components of the Xilin small partridge duck’s mitochondrial genome were similar to those of otherAnatidaein gene arrangement and composition. The complete mitochondrial genome of the Xilin small partridge duck should provide essential information for understanding phylogenetic relationships of duck mitochondrial genome.
