Danshen, Salvia miltiorrhiza Bunge, is one of the most widely used herbs in traditional Chinese medicine, wherein its rhizome/roots are particularly valued. The corresponding bioactive components include the tanshinone diterpenoids, the biosynthesis of which is a subject of considerable interest. Previous investigations of the S. miltiorrhiza transcriptome(More)
Medicinal plants of the Panax genus belonging to Araliaceae family are well-known, rare plants used as tonics in traditional Chinese medicine and have been described in the Chinese Pharmacopoeia. Because of the high price and the huge human demand, these commercial products often contain adulterants. In this study, 377 sequences from four species were(More)
Adulterant herbal materials are a threat to consumer safety. In this study, we used DNA barcoding to investigate the proportions and varieties of adulterant species in traditional Chinese medicine (TCM) markets. We used a DNA barcode database of TCM (TCMD) that was established by our group to investigate 1436 samples representing 295 medicinal species from(More)
BACKGROUND DNA barcoding can be used to authenticate Ganoderma species for safe use. This study aims to identify commercial products containing Ganoderma using DNA barcoding. METHODS We used 63 internal transcribed spacer (ITS) 2 sequences of Ganoderma species from 33 newly-sequenced wild samples, crude drugs, mycelia, spores, and authentic extracts and(More)
BACKGROUND American ginseng (Panax quinquefolius L.) is renowned worldwide for its eutherapeutic effects. The replantation of American ginseng usually fails due to problems associated with continuous cropping. An imbalance in the microbial community is thought to be responsible for this, but the overall changes in microbial communities under a continuous(More)
We cloned and analyzed the two genes of the 1-hydroxy-2-methyl-2-(E)-butenyl-4-diphosphate reductase (HDR) gene family from Huperzia serrate. The two transcripts coding HDR, named HsHDR1 and HsHDR2, were discovered in the transcriptome dataset of H. serrate and were cloned by reverse transcription-polymerase chain reaction (RT-PCR). The physicochemical(More)
