Genetic characterization of the Longsheng duck ( Anas platyrhynchos ) based on the mitochondrial DNA.

The complete mitochondrial genome sequence of the Longsheng duck was measured by PCR-based methods. Our research findings revealed that the entire mitochondrial genome of the Longsheng duck was 16,603 bp (GenBank accession number: KJ739616). The contents of A, T, C, and G in the mitochondrial genome were 29.22%, 22.21%, 32.79% and 15.77%, respectively, which were similar to the majority of most avian species. The complete mitochondrial genome of the Longsheng duck contains 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and one control region. Components of the Longsheng duck’s mitochondrial genome were similar to those of otherAnas platyrhynchosin gene arrangement and composition. The complete mitochondrial genome of the Longsheng duck should provide essential information for understanding phylogenetic relationships of duck mitochondrial genome. [ABSTRACT FROM AUTHOR]
