| Summary: | The complete mitogenome sequence of the Siberian large-toothed shrew (Sorex daphaenodon) was determined using long PCR. The genome was 17,407 bp in length and contained 13 protein-coding genes, 2 ribosomal RNA genes, 23 transfer RNA genes, 1 origin of L strand replication, and 1 control region. The overall base composition of the heavy strand is A (33.1%), C (24.7%), T (29.0%), and G (13.2%). The base compositions present clearly the A–T skew, which is most obvious in the control region and protein-coding genes. The extended termination-associated sequence domain, the central conserved domain, and the conserved sequence block domain are defined in the mitochondrial genome control region of the Siberian large-toothed shrew. Mitochondrial genome analyses based on MP, ML, NJ, and Bayesian analyses yielded identical phylogenetic trees. The 11 Sorex species formed a monophyletic group with the high bootstrap value (100%) in all examinations.
