Although resveratrol-forming stilbene synthase (STS) genes have been well characterized in many plant species, there are only a few descriptions about STS genes from Polygonum cuspidatum Sieb. et Zucc, an important medicinal crop in Asian countries. To evaluate the biological functions of a Polygonum cuspidatum resveratrol synthase gene (PcRS), the PcRS(More)
The compound 2,3,5,4'-tetrahydroxy stilbene-2-O-ß-d-glucoside (THSG) synthesized by Fallopia multiflora (F. multiflora) exhibits pharmacological potency. However, the mechanistic details of its biosynthesis pathway are still vague. To clear this ambiguity, we performed de novo transcriptome assembly and digital gene expression (DGE) profiling analyses of F.(More)
In order to develop an efficient identification method for Fallopia plants and drugs, molecular analysis of the partial matK gene sequences was performed on 6 Fallopia species. Based on the matK sequences, a phylogenetic tree was constructed, which showed that different populations of inter- and intra-species could be specified and distinguished. The matK(More)
Type III polyketide synthases (PKSs) from plants produce a variety of plant secondary metabolites with notable structural diversity and biological activity. These metabolites not only afford plants the ability to defend against pathogen attack and other external stresses, but also exhibit a wide range of biological effects on human health. Several plant(More)
