Abstract:
Over past decades plant tissue culture has emerged as an alternative of whole plant cultivation in the production of valuable secondary metabolites. Adventitious roots culture of Panax ginseng and Echinacea purpure has reached the scale of 1?10 kL. Some molecular biological techniques, such as transgenic technology and genetic stability are increasingly used in the studies on plant tissue cultures. The studies on elicitors have deepened into the induction mechanism, including signal molecules, functional genes, and so on. More and more biological elicitors, such as A. niger and yeast are used to increase the active compounds in plant tissue cultures. We also discussed the application of synthetic biology in the studies on biosynthesis of artemisinin, paclitaxel, and tanshinon. The studies on active ingredients biosynthesis of medicinal plants provide unprecedented possibilities to achieve mass production of active ingredients. Plant tissue cultures can not only produce active ingredients but also as experimental materials for biosynthesis. In order to improve the contents of active compounds in medicinal plants, following aspects could be carried out gene interference or gene silencing, gene overexpression, combination with chemical synthesis, application of elicitors, and site-directed mutagenesis of the key enzymes.
