[Identification of common medicinal snakes in medicated liquor of Guangdong by COI barcode sequence]
Objective:
To identify the common snakes in medicated liquor of Guangdong using COI barcode sequence,and to test the feasibility.
Methods:
The COI barcode sequences of collected medicinal snakes were amplified and sequenced. The sequences combined with the data from GenBank were analyzed for divergence and building a neighbor-joining(NJ) tree with MEGA 5.0.
Results:
The genetic distance and NJ tree demonstrated that there were 241 variable sites in these species, and the average (A + T) content of 56.2% was higher than the average (G + C) content of 43.7%. The maximum interspecific genetic distance was 0.2568, and the minimum was 0. 1519. In the NJ tree,each species formed a monophyletic clade with bootstrap supports of 100%.
Conclusion:
DNA barcoding identification method based on the COI sequence is accurate and can be applied to identify the common medicinal snakes.
