Sequence Analysis of the Complete Mitochondrial Genome of Niviventer confucianus

Abstract: Niviventer confucianus belongs to genus Niviventer， family Muridae， order Rodentia， and it is involved in few molecular phylogenetic studies. The complete mitochondrial genome (mitogenome) sequence of N. confucianus was firstly obtained with PCR and sequencing techniques using 34 pairs of specific primes. The mitogenome (the GenBank accession number: KJ152220) was 16 281 bp in length and the nucleotide composition was 34.0% A， 28.6% T， 24.9% C and 12.5% G. The mitogenome consisted of 13 protein-coding genes， 22 tRNAs， 2 rRNAs and 1 control region， and the genome organization and sequence characters didn’t differ greatly from those of mitogenomes of N. excelsior， Mus musculus， and Rattus norvegicus， though small difference existed. The genetic distance among mitogenomes of four species showed that the relationship between N. confucianus and N. excelsior was closest， while the relationship between N. confucianus and M. musculus was farthest. This work provides valuable data for phylogenetic analysis of rodents with complete mitogenome information.
