The complete mitogenome of lesser striped shrew Sorex bedfordiae (soricidae)

Abstract

The Sorex genus is type genus in Soricidae. Most of them lack comprehensive biological data. In this study, the complete mitochondrial genome sequence of Sorex bedfordiae was determined. The mitogenome is 17 160 base pairs in length and contains 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and one control region. The nucleotide sequence data of 12 heavy-strand protein-coding genes of Sorex bedfordiae and other 10 species in Soricidae were used for phylogenetic analyses. Tree constructed using Bayesian phylogenetic methods demonstrated Sorex bedfordiae as a sister to Sorex cylindricauda. Phylogenetic analyses further confirmed that Blarinella diverged prior to Sorex and Anourosorex, but Episoriculus differentiated earlier than Neomys and Nectogale within subfamily Soricinae.
