Background Gypenosides are a group of triterpene saponins from Gynostemma pentaphyllum that are the same as or very similar to ginsenosides from the Panax species. Several enzymes involved in ginsenoside biosynthesis have been characterized, which provide important clues for elucidating the gypenoside biosynthetic pathway. We suppose that gypenosides and ginsenosides may have a similar biosynthetic...
Dendrobium officinale Kimura et Migo (Orchidaceae) is a traditional Chinese medicinal plant. The stem contains an alkaloid that is the primary bioactive component. However, the details of alkaloid biosynthesis have not been effectively explored because of the limited number of expressed sequence tags (ESTs) available in GenBank. In this study, we analyzed RNA isolated from the stem of D. officinale...
