Identification of species within Tetrastigma (Miq.) Planch.(Vitaceae) based on DNA barcoding techniques

摘要

Many species of Tetrastigma(Miq.) Planch.(Vitaceae) have long been used as medicinal plants in China,and some are endangered due to overexploitation.Although adulterants are often added to traditional Chinese medicines,there is no reliable or practical method for identifying them.In this study,we used four markers(rbcL,matK,trnH-psbA,and internal transcribed spacer [ITS]) as DNA barcodes to test their ability to distinguish species of Tetrastigma.The results indicated that the best barcode was ITS,which sho...
