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.
