title: Sequence and phylogenetic analysis of the complete mitochondrial genome of Lasiopodomys mandarinus mandarinus (Arvicolinae, Rodentia).
abstract: Mandarin vole (Lasiopodomys mandarinus) is a subterranean rodent that is often used as a model for studying subterranean hypoxic stress in mammals. However the taxonomy of this species is still in dispute. Mitochondrial DNA (mtDNA) has long been used for phylogenetic reconstruction and, in this study, the complete mitochondrial genome of L. mandarinus mandarinus was sequenced. Our results showed that the mitochondrial genome of L. m. mandarinus is a circular molecule of 16,367bp, which contains 13 protein-coding genes, 22 tRNA and 2 rRNA genes. Except for the 8 tRNA and ND6 genes, all other mitochondrial genes are encoded on the heavy strand. We also analyzed the phylogenetic position of L. mandarinus in respect to the tribe Arvicolini using the sequence of complete Cytb gene, 2rRNA genes and 12 protein-coding genes, and maximum likelihood and Bayesian methods. Our results gave further support to the species status of L. mandarinus and the generic status of Lasiopodomys.
