The complete mitochondrial genome of Eurasian water shrew (Neomys fodiens)

Abstract

The complete mitogenome sequence of Eurasian water shrew (Neomys fodiens) was determined using long PCR. The genome was 17,260 bp in length and contained 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes and 1 control region. The overall base composition of the heavy strand is A (33.0%), C (23.2%), T (30.9%) and G (12.9%). The base compositions present clearly the A–T skew, which is most obviously 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 Eurasian water shrew. Mitochondrial genomes analyses based on MP, ML, NJ and Bayesian analyses yielded identical phylogenetic trees. Neomys elegans, Soriculus fumidus, and N. fodiens formed a monophyletic group with the high bootstrap value (100%) in all examinations. This clade with the Anourosorex squamipes as the sister taxon to Sorex.
