Organization of the complete mitochondrial genome and its evolution in sable
The 16 523 bp mitochondrial DNA (mtDNA) of sable (Mattes zibellina) was sequenced by polymerase chain reaction(PCR) and direct sequencing methods. It contained 3 protein-coding genes,2 rRNA genes,22 tRNA genes and a non-coding control region. The base composition was A-32. 0%, C-27.6%, G-14.7% and T-25.8%. The third location of codon in the protein-coding genes, which continually use incomplete termination codon T or TA (7), had a higher possibility of A and C. The sequence has been deposited in the GenBank database under accession number FJ429093. Combined with the mitochondrial genome sequences of six other species from Mustilidae and six D-Loop sequences of Mattes, available from GenBank, the phylogenetic evolutionary relationship of Mustelidae and Mattes was analyzed, using the Maximum Parsimony method with the tiger and Eurasian badger as the outgroups. The results show that the seven species of Mustelidae can be divided into three branches: Lutrinae and Mephitinae, Japanese marten and wolverine, as well as sable and Eurasian badger. It also indicates that Mustelidae is not a monophyletie group. Sable not only has a close relationship with Melinae of Mustelidae, but also a near relationship with American marten and stone marten of Mattes.
