Sequencing and analysis of the complete mitochondrial genome of Eothenomys eleusis Thomas 1911 from China and its phylogenetic analysis.

The complete mitogenome sequence of Eothenomys eleusis Thomas 1911 was determined using PCR. A circular double-stranded structure makes up the mitochondrial genome of E. eleusis. The complete length of the mitochondrial genome is 16,419 bp. The mitochondrial genome of E. eleusis included 13 protein-coding genes, 1 control region, 22 tRNA genes, 2 rRNA genes and 1 origin of L strand replication. The total base composition of E. eleusis mitochondrial genome was A (32.6%), T (26.3%), G (13.6%) and C (27.5%). We found significant A-T skew in base composition, especially in control regions and protein-coding genes. E. eleusis was supported by bootstrap values of 100%. This study verifies the evolutionary status of E. eleusis in Myodini tribe of Cricetidae at the molecular level. The mitochondrial genome would be a significant supplement for the E. eleusis genetic background. [ABSTRACT FROM AUTHOR]
