Abstract:
In this study, the psbA-trnH sequence was used as DNA barcoding to evaluate the accuracy and stability for identification of Bamboo shavings, Concretio Silicea Bambusae and their closely related species. 56 samples were collected and conducted the DNA extraction. Obtained sequences were assembled using the CodonCode Aligner V4.2, the genetic distances and NJ tree were computed and constructed using MEGA 5.0. The results shows that the maximum intra-specific K2P distances were less than the minimum inter-specific K2P distances. The NJ tree indicated that Bamboo shavings, Concretio Silicea Bambusae and their closely related species can be distinguished from each other clearly, except for Bambusa tuldoides Munro and Bambusa textilis, which perhaps attributed to their closely genetic relationship.
