Abstract
Dammarenediol-II synthase catalyzes the cyclization of 2,3-oxidosqualene to dammarenediol-II, which is the basic triterpene skeleton in dammarene-type saponin (ginsenosides) in Panax ginseng. Dammarenediol-II is a useful candidate both for pharmacologically active triterpenes and as a defense compound in plants. Dammarenediol-II is present in the roots of P. ginseng in trace amounts because it is an intermediate product in triterpene biosynthesis. In this work, we established the production of dammarenediol-II via cell suspension culture of transgenic tobacco. The dammarenediol-II synthase gene (PgDDS) isolated from P. ginseng was introduced into the Nicotiana tobacum genome under the control of 35S promoter by Agrobacterium-mediated transformation. Accumulation of dammarenediol-II in transgenic tobacco plants occurred in an organ-specific manner (roots > stems > leaves > flower buds), and transgenic line 14 (T14) exhibited a high amount (157.8 μg g−1 DW) of dammarenediol-II in the roots. Dammarenediol-II production in transgenic tobacco plants resulted in reduced phytosterol (β-sitosterol, campesterol, and stigmasterol) contents. A cell suspension culture was established as a shake flask culture of a callus derived from root segments of transgenic (T14) plants. The amount of dammarenediol-II production in the cell suspension reached 573 μg g−1 dry weight after 3 weeks of culture, which is equivalent to a culture volume of 5.2 mg dammarenediol-II per liter. Conclusively, the production of dammarenediol-II in a cell suspension culture of transgenic tobacco can be applied to the large-scale production of this compound and utilized as a source of pharmacologically active medicinal materials.
