The complete mitochondrial genome of the Jingxi duck (Anas platyrhynchos).

The entire mitochondrial genome of Jingxi duck from China was 16,603 bp in length, and has been analyzed for gene locations, length, start codons and stop codons. With the base composition of 29.20% for A, 22.19% for T, 32.82% for C, 15.79% for G, so the percentage of A and T (51.39%) was slightly higher than those of G and C. The Jingxi duck mitochondrial genome contained two ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes and one non-coding control region (D-loop region). The arrangement of these genes was the same as most birds. The complete mitochondrial genome sequence of the Jingxi duck will be useful for phylogenetics, and provide an important data set for further study on the germplasm resources.
