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 16,367 bp, 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 . [ABSTRACT FROM AUTHOR]

Manchurian Zokor (Myospalax psilurus) is a common subterranean rodents which have a wide distribution in Transbaikalia, east Mongolia, east and central China, and Far East of Russian. The complete mitochondrial (MT) genome ofM. psilurushas been determined in this study. It is a 16 360 bp circular molecule containing 13 protein-coding, 22 tRNAs and 2 rRNAs genes. Except for the seven tRNA and Nd6 genes, all other mitogenes are encoded on the heavy strand. The overall nucleotide composition of the H-strand is 33.68% A, 28.77% T, 25.35% C, and 12.17% G. Total A + T content is 54.12%. [ABSTRACT FROM AUTHOR]

Mandarin voles (Lasiopodomys mandarinus) is a subterranean rodent species that are often used as a model for studying subterranean hypoxic stress in mammals. Its subspeciesL. m. mandarinusspan in cropland in most area of north China and is regarded as an agricultural pest. In this paper, the complete mitochondrial genome ofL. m. mandarinushas been determined. Our results showed that the mitochondrial genome ofL. m. mandarinusis a circular molecule of 16 367 bp, which contents 13 protein-coding, 22 tRNAs and 2 rRNAs genes. The overall base composition of the heavy strand is 32.47% A, 27.04% T, 27.01% C, and 13.47% G. with an AT content of 59.51%. [ABSTRACT FROM AUTHOR]
