Hog deer(Axis porcinus)is a small mammal and listed in the International Union for Conservation of ***,phylogenetic position of hog deer within Axis genus has remained *** the present study,we first assembled complete mitochondrial genome of Chinese hog deer reared in Chengdu Zoo,Sichuan,by the second-generation sequencing *** newly assembled mitochondrial genome of hog deer is 16376 bp in length and consists of 13 protein-encoding genes,23 transfer RNA genes and 2 ribosomal RNA *** analyses based on complete mitochondrial genome and cytochrome b gene sequences revealed that hog deer is closely clustered together and placed with sister taxon of spotted deer(***),which therefore supported monophyletic statue of Axis ***,considerable genetic differentiation,up to 139 mutations of complete mitochondrial genome was revealed between geographical populations of hog deer in France and Southeast ***,only six variable sites(nucleotide diversity of 0.00007)and four haplotypes(haplotype diversity of 0.533)were totally detected among ten newly sequenced Chinese hog *** results provide a better understanding on the phylogeny of hog deer.
