Identification of Original Plants of Lycii Cortex by Multiplex Allele-specific PCR
as the original plants of Lycii Cortex simply and efficiently by multiple allele-specific polymerase chain reaction (PCR).
Method
2
The chloroplast genome sequences of
L. chinense
and
L. barbarum
were downloaded from the Chloroplast Genome Information Resource (CGIR), and then IdenDSS was employed to screen out the specific single nucleotide polymorphism (SNP) sites between the two plants. Primer 5.0 was used to design the specific primers, including primers GQ-F/R for identifying
L. chinense
and primers NX-F/R for identifying
L. barbarum.
Furthermore, the primer concentration ratio, annealing temperature, cycles, and
Taq
enzyme were optimized to establish the optimal PCR system and conditions for plant identification. Finally, the applicability of the established method was examined with the plant samples collected from different regions.
Result
2
The PCR with GQ-F/R∶NX-F/R concentration ratio of 2∶1 at the annealing temperature at 59 ℃ and for 30 cycles showed specific bands at 183 bp and 295 bp, respectively, for
L. chinense
and
L. barbarum
samples from different regions.
Conclusion
2
The established PCR approach can simply, rapidly, and efficiently identify the original plants of Lycii Cortex, serving as a new method for the discrimination between
L. chinense
and
L. barbarum
. Moreover, the method provides technical support for the research and development of classic famous prescriptions containing Lycii Cortex.
