Abstract:
We determined a complete mitochondrial genome of Episoriculus leucops. This mitogenome is a circular molecule with 16,838 bp in length, containing 13 protein-coding genes, 22 transfer RNA genes (tRNA), and two ribosomal RNA genes (rRNA). This mitochondrial genome has a base composition of 32.8% A, 29.2% T, 24.9% C, and 13.1% G. We reconstructed Bayesian phylogenetic tree by taking advantage of 19 species belonging to subfamily Soricinae. Phylogenetic tree shows that the long-tailed red-toothed shrew belongs to genus Episoriculus, and it is the closest relationship with E. caudatus. This mitochondrial genome provides an important resource for addressing taxonomic issues and studying molecular evolution.
