ABSTRACT
Objective:
For rapid identification of Houttuynia cordata and Gymnotheca chinensis, the specific PCR for mutual authentication of them was established based on the SNPs in matK sequence.Methods:
H. cordata and G. chinensis samples from different origins were collected, total DNA of all samples was extracted, and the matK gene was seqenced. SNPs in the matK sequences of all the samples were found by ClustulX 2.1 program. Primers for identifying H. cordata and G. chinens were designed according to the SNP site, and specific PCR method was established to identify them, for rapid detection by addition of SYBR Green I dye. In addition, constructing a multi-PCR reaction system, and then the PCR reaction system was optimized.Results:
The band special for H. cordata (185 bp) and band special for G. chinensis (389 bp) were found using specific PCR reaction and multi-PCR reaction, and SYBR Green I dye can be used for rapid detection.Conclusion:
The multi-PCR reaction system could be used to identify H. cordata and G. chinensis.
