Comparison of Chloroplast trnL-F Sequences of 5 Common Potentilla species in Jilin Province of China

摘要

To find the differences in the trnL-F sequences and provide scientific data for the authentication of Potentilla chinensis and its related species, we extracted the genome DNA from the leaves of 5 common Potetilla species in Jilin Province, amplified the trnL-F region using universal primers of angiosperm, and sequenced the purified PCR products directly. We found that the trnL-F sequences of different species of Potentilla are significantly different. So trn-L sequence analysis and other methods derived from it can be used in authentication of Potentilla.
