The complete mitochondrial genome of Celebes wild boar, Sus celebensis (Cetartiodactyla: Suina: Suidae), and comparative mitochondrial genomics of the Sus species

Abstract

In this study, the complete mitochondrial (mt) genome sequence of Sus celebensis was firstly determined. The total genome was 16,481 bp in length and its overall base composition was estimated to be 34.9% for A, 25.8% for T, 26.2% for C, 13.1% for G, respectively, indicating an A-T (60.7%)-rich feature in Celebes wild boar mitogenome. It harbored 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes and a non-coding control region (D-loop region). Comparisons with other publicly available pig mitogenomes revealed abundant nucleotide diversity. This complete mitgenome sequence would accelerate further studies on pig evolution and domestication that will enhance germplasm preservation and breeding programs of the pig gene pool.
