4. Conclusion
We have sequenced the complete mitochondrial genome of N. andersoni for the first time and compared it with closely related species of the family Muridae. The mitochondrial genome structural features were similar to other species in genus Niviventer . In the phylogenetic analysis of sequences of the 13 PCGs, the PCGs excluding ND6 and the complete mitogenome without D-loop, N. andersoni was consistently the most similar to N. excelsior , consistent with previous studies based on single cytb gene sequences and morphological characteristics. Phylogenetic analysis based on the complete mitogenome showed that N. confucianus had the closest relationship to N. andersoni and N. excelsior , rather thanN. fulvescens and N. cremoriventer as previously suggested. The availability of complete mitochondrial genome of N. andersoni should be helpful to better understand evolution within the genus Niviventer, as well as its relationship to other murid rodents.
