Abstract
Two novel mitogenomes of Eozapus setchuanus (KJ648495) and Sicista concolor (KJ648496) were reported and their total lengths were 16,630Â bp and 16,493Â bp, respectively. Both mitogenomes which were analogous to other rodent mitogenomes, contained 13 protein-coding genes, 22 tRNAs, 2 rRNAs, and a control region. Specifically, the ND2 gene of S. concolor has three amino acids lesser than that of two other Dipodidae species (E. setchuanus and Jaculus jaculus) due to a premature termination codon in the 3â² end. We detected a tandem repeat cluster of 221Â bp and 274Â bp in the control region of S. concolor and E. setchuanus, respectively. Along with phylogenetic relationship analysis, we speculated that the tandem repeats in control regions might be common in Dipodinae species. Our phylogenetic analysis using concatenated mitochondrial gene datasets suggested five suborder and 16 family monophyletic groups in 54 rodent taxa sampled and strongly supported a basal position of the squirrel-related clade (PPÂ =Â 1; BPÂ =Â 100). Dipodidae had a sister-group relationship with Muroidea, and Sicistinae was in the base of Dipodidae clade. The complete mitochondrial genomes showed high resolution in deep-level phylogenetic relationship reconstructions of Rodentia.
