The complete mitochondrial genome of Juema pig Sus scrofa (Suina: Suidae) from southern Gansu

Juema pig is a kind of rare and special pig which is well adapted to high altitude, cold climate and harsh natural environment. The complete mitochondrial genome of Juema pig Sus scrofa is a circular molecule of 16 532 bp in length, containing 13 protein-coding genes, two ribosomal RNAs, 22 transfer RNAs, and a control region. The A + T content of the overall base composition of H-strand is 60.7% (T: 26.2%; C: 26.0%; A: 34.5%; G: 13.3%). ND4L gene begins with GTG as start codon, ND2, ND3, and ND5 genes begin with ATA as a start codon, and other nine proteincoding genes start with ATG. Cyt b gene is terminated with AGA as stop codon, ND1 and ND2 genes are terminated with TAG as stop codon, COII, COIII, ND3, and ND4 end with T, while ATP6, ATP8, COI, ND4L, ND5, and ND6 end with TAA. In addition, the phylogenetic relationships from neighbor-joining analyses based on the 13 concatenated PCGs indicated (Tylopoda (Suina (Ruminantia (Hippopotamidae, Cetacea)))).
