The complete mitochondrial genome of Dapulian pig (Sus scrofa) and a phylogenetic study.

The two types of mitochondrial genomes of Dapulian pig has been sequenced and annotated completely. The entire genome is 16,610 bp in length with an A + T content of 60.6% (GenBank accession No. MG009445, MG009446). This mitochondrial genome consisted of 13 protein-coding genes, 2 ribosomal RNA subunits and 22 transfer RNAs, and 1 D-loop control regions. A phylogenetic tree with the near-complete mitochondrial genome sequences of two types of Dapulian pigs together with 17 other Chinese pig breeds was constructed. The results can be subsequently used to provide information for pig phylogenetic and insights into the evolution of genomes. The mitochondrial genome would play an important role in population genetics and phylogenetic analysis of Sus scrofa.
