Sequencing and analysis of the complete mitochondrial genome of flat-skulled shrew (Sorex roboratus) from China.


ABSTRACT: The complete mitogenome sequence of flat-skulled shrew (Sorex roboratus) was determined using long PCR. The genome was 17,153?bp in length and contained 13 protein-coding genes, 2 ribosomal RNA genes, 22 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 (24.4%), T (29.4%), and G (13.1%). 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 flat-skulled shrew. Mitochondrial genome analyses based on MP, ML, NJ and Bayesian analyses yielded identical phylogenetic trees. The five Sorex species formed a monophyletic group with the high bootstrap value (100%) in all examinations.
