[Identification of Cervus nippon, C.elaphus and their hybridize samples based on COI and SRY gene]

For rapid identification of Cervus nippon, C. elaphus and their hybridize samples, the specific PCR for mutual authentication of them was established based on the SNPs in COI and SRY sequence. C. nippon, C. elaphus and their hybridize samples were collected from different origins, total DNA of 24 identified samples were extracted, and the COI and SRY gene was seqenced. SNPs in the COI and SRY sequences of the samples were found by Clustul X 2.1 program. Primers for identifying C. nippon and C. elaphus were designed according to the SNP site, two multi-PCR reaction system were established to identify them. In addition, 24 samples which were randomly collected in different herbal medicine market were identified. The band special for C. nippon (232 bp)and band special for C. elaphus (518 bp) based on COI sequence,and the band special for C. nippon (803 bp)and band special for C. elaphus (425 bp) based on SRY sequence, were found using multi-PCR reaction, and three of the twenty-four samples were identified as the hybridize samples. The multi-PCR reaction system could be used to identify C. nippon, C. elaphus and their hybridize samples.
