Allocricetulus eversmanniis a unique species in theAllocricetulus, belonging to the Cricetinae group. Its complete mitochondrial genome was first obtained and the total length was 16,282 bp. Protein-coding genes approximately accounted for 69.6% of the complete genome. The heavy strand contained 30% A, 14.4% G, 27.9% C, 27.7% T. Compared with most other mammals, it had the same arrangement and similar length of vary genes or regions. The complete mitochondrial genome ofA. eversmanniwas conducive to more accurately locate its taxonomic status in Cricetinae and its evolutionary history. At the same time, it provided significant information about consummation ofA. eversmannigene pool. [ABSTRACT FROM AUTHOR]

Dipus sagittaandEuchoreutes nasoare both monotypic genus, both of them belong to the family of Dipodidae, andE. nasois an Endangered species (EN) defined by the World Conservation Union. The length of its complete mitochondrial sequence ofD. sagittaandE. nasois 16,664  bp and 16,705  bp, respectively. Phylogenetic analysis displayed thatD. sagitta, Jaculus jaculus,andE. nasowere classified into the same cluster. This result was consistent with that of primary morphological taxonomy. The mitochondrial genome ofD. sagittaandE. nasowould 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.

Meriones meridianusbelongs to the genusMerionesin Gerbillinae. Total length of complete mitochondrial genome ofM. meridianusis 16,376 bp and the heavy strand contains 32.8% A, 13.1% G, 25.3% C and 28.8% T. Sequences of protein-coding genes are 11,341 bp in length, accounting for 69.25%, approximately. Results of phylogenetic analysis shown thatM. meridianusandMeriones unguiculatuswere clustered in a single branch. This conclusion would be an important data for relevant studies about the genusMeriones, and mitochondrial genome would be an important supplement for the gene pool of Rodentia.It would play a pivotal role in researches about phylogeography and proteomics involvingM. meridianusas well.

Meriones libycusbelongs to the genusMerionesin Gerbillinae, its complete mitochondrial genome is 16,341 bp in length. The heavy strand contains 32.8% A, 13.1% G, 25.3% C, 28.8% T, protein-coding genes approximately accounting for 69.54%. Results of phylogenetic analysis showed thatM. libycusandMeriones unguiculatuswere clustered together, and it was consistent with that of primary morphological taxonomy. This study verifies the evolutionary status ofM. libycusinMerionesat the molecular level. The mitochondrial genome would be a significant supplement for the gene pool of Rodentia and the conclusion of phylogenetic analysis could be an important molecular evidence for the classification of Gerbillinae.

Stylodipus telumbelongs to the genusStylodipusin the subfamily of Dipodinae. We got its complete genome first and it is 16,696 bp in length, the heavy strand contains 31.0% A, 13.8% G, 27.3% C, 27.9% T. Among them, protein-coding genes take up approximately 67.90% of the complete sequence. Trees constructed through phylogenetic analysis showedS. telumandJaculus jaculuswere clustered in one branch belonging to the family Dipodinae. This conclusion was identical to the former result by the methods of morphological taxonomy, and it would be convenient for further research onS. telumand other jerboa. [ABSTRACT FROM AUTHOR]
