DNA barcoding of populations of Fallopia multiflora, an indigenous herb in China
Fallopia multiflora, locally known as Heshouwu, is one of the most important and widely used Chinese medicinal herbs. However, there is still considerable confusion concerning its different provenances. DNA barcoding is a recent aid to taxonomic identification and uses a short standardized DNA region to discriminate plant species. We assessed the applicability of 4 candidate DNA barcodes (matK, rbcL, psbA-trnH, and ITS2) to identify populations of F. multiflora.
