Abstract
The complete mitochondrial genome was sequenced and annotated newly from an individual of Niviventer fulvescens (Muridae) from Sichuan province. The total length of the N. fulvescens mitogenome is 16 296 bp and contains 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes and a control region, with a base composition of 34.3%A, 29.1%T, 24.2%C and 12.4%G. The nucleotide sequence data of 12 heavy-strand protein-coding genes of N. fulvescens and other 18 rodents were used for mitochondrial genome phylogenetic analyses. Bayesian phylogenetic tree demonstrated the genus Niviventer was embedded within the genus Leopoldamys, although three Niviventer species constituted a monophyletic group. More complete mitochondrial genome sequences are required to illuminate the molecular phylogenetic relationship between Niviventer and Leopoldamys.
