The complete mitochondrial genome sequence of the Luchuan pig was measured by PCR-based methods, primer-walking sequencing, and fragment cloning. The entire mitochondrial genome of the Luchuan pig was identified as a circular molecule consisting of 16,730 bp (GenBank accession number: KP126954). The contents of A, T, C, and G in the mitochondrial genome were found to be 34.65%, 25.80%, 26.19%, and 13.36%, respectively. The complete mitochondrial genome of the Luchuan pig contains a typical structure, including 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and one control region (D-loop region). This complete mitochondrial genome sequence provides essential information in understanding phylogenetic relationships among Sus scrofa domestic mitochondrial genomes.
