Characterization of the complete mitochondrial genome of Indochinese Forest Rat, Rattus andamanensis (Rodentia: Muridae) and its phylogenetic analysis

Abstract

We obtained the complete mitochondrial genome of the Indochinese Forest Rat (Rattus andamanensis). The genome is 16,304 bp in length and contains 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes, and 1 control region. The composition and arrangement of genes are analogous to other vertebrates. We used all PCGs to construct phylogenetic tree for R. andamanensis and other 15 Rattus species available on GenBank. The topology indicated that the genus Rattus has two groups and R. andamanensis has a close relationship with R. baluensis, R. tiomanicus, R. rattus, and R. tanezumi.
