The complete mitochondrial genome of bearded pig, Sus barbatus, and comparative mitochondrial genomics of Cetartiodactyla

Abstract

In this study, the complete mitochondrial genome sequence of bearded pig, Sus barbatus, with the total length of 16,480 bp, is determined for the first time. This mitogenome harbors 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and one control region (D-loop). The overall base composition is A (34.80%), C (26.07%), G (13.12%), and T (26.01%), so the slight A–T bias (60.81%) was detected. Most of the genes are distributed on the H-strand, except for the ND6 subunit gene and eight tRNA genes. To obtain the phylogenetic relationship of the Cetartiodactyla, 11 mitochondrial genomes were used for phylogenetic analysis. The mitochondrial genome of S. barbatus presented here will contribute to a better understanding of the population genetics.
