The complete mitochondrial genome analysis of the tiger (Panthera tigris)

The complete mitochondrial genomes of five tiger samples from three subspecies (P. t. sumatrae, P. t. altica, and P. t. tigris) were successfully obtained by using 26 specifically designed Panthera-specific primer sets. The genome organization and gene arrangement of the five tiger samples were similar to each other; however polymorphic tandem repeat sequences were observed in the control region (CR). This led to a difference in the genome lengths obtained from these five samples with an average size of 16,994 bp for the five tiger mitochondrial genomes. The nucleotide base composition was on average as follows: A, 31.8%; T, 27.0%; C, 26.6%; G, 14.6% and exhibited compositional asymmetry. Most of tiger mitochondrial genome characteristics are similar to those of other common vertebrate species; however, some distinctive features were observed in the CR. First, the repetitive sequence 2 (RS 2) contained two repeat units of 80 bp and the first 15 bp of what would be the third repeat motif. The repetitive sequence 3 (RS 3) contained 47–50 repeat motifs of a shorter 8 bp (ACGTAYAC)n. Second, length heteroplasmy polycystosine (poly-C) stretches was observed at the end of the HV I locus in all tiger samples

Where does this tiger come from? — A robust molecular technique for simultaneous identification of endangered species and subspecies

The Convention on the International Trade in Endangered Species of Wild Fauna and Flora (CITES) monitors the international trade in endangered animal and plant species; a high profile example is the tiger, Panthera tigris. We report on the application of a SNaPshot multiplex technique to simultaneously identify tiger species and subspecies; this test is based on identification of SNPs within the tiger mitochondrial genome. Mitochondrial DNA sequences from four of the five extant putative tiger subspecies were obtained and combined with DNA sequence data from 492 tiger and 349 other mammalian species. A total of 11 SNP loci were identified: five specific for tiger; three specific to Panthera tigris sumatrae and; three specific to P. t. tigris. The multiplex assay was able to reliably identify 15 voucher tiger samples. The sensitivity of the test was 15,000 mitochondrial DNA copies, indicating that it will work on trace amounts of tissue, bone or hair
