Phylogenetic analysis of Dipus sagitta and Euchoreutes naso (Rodentia: Dipodidae) based on the mitochondrial genomes.

AbstractDipus sagitta and Euchoreutes naso are both monotypic genus, both of them belong to the family of Dipodidae, and E. naso is an Endangered species (EN) defined by the World Conservation Union. The length of its complete mitochondrial sequence of D. sagitta and E. naso is 16,664  bp and 16,705  bp, respectively. Phylogenetic analysis displayed that D. sagitta, Jaculus jaculus, and E. naso were classified into the same cluster. This result was consistent with that of primary morphological taxonomy. The mitochondrial genome of D. sagitta and E. naso would be a key supplement for the gene pool of Rodentia and the conclusion of phylogenetic analysis was an important molecular evidence for the taxonomic status of the two species.
