Characterization of the complete mitochondrial genome of Dongyangjiang White-toothed Shrew, Crocidura dongyangjiangensis (Eulipotyphla: Soricidae) and its phylogenetic analysis

The complete mitochondrial genome of the Dongyangjiang White-toothed Shrew (Crocidura dongyangjiangensis), a newly discovered Crocidura species, is sequenced and characterized. The total length of the genome is 16,883 bp, and has similar base composition and gene arrangement to other vertebrates. It contains 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA), 22 transfer RNA (tRNA), a replication origin (OL) and a control region. The phylogenetic tree shows that C. dongyangjiangensis was fully resolved in a clade with three other species of Crocidura and it has a sibling relationship with Crocidura tanakae. This analysis reveals the evolutionary relationship of 16 Crocidura species.
