Ginsenosides are the main active ingredients in Chinese medicinal ginseng; 2,3-oxidosqualene is a pre-cursor metabolite to ginsenosides that is present in rice. Because rice lacks a key rate-limiting enzyme(dammarenediol-II synthase, DS), rice cannot synthesize dammarane-type ginsenosides. In this study,the ginseng (Panax ginseng CA Mey.) DS gene (GenBank: AB265170.1) was transformed into rice usingagrobacterium, and 64 rice transgenic plants were produced. The Transfer-DNA (T-DNA) insertion sitesin homozygous lines of the T2generation were determined by using high-efficiency thermal asymmetricinterlaced PCR (hiTAIL-PCR) and differed in all tested lines. One to two copies of the T-DNA were presentin each transformant, and real-time PCR and Western blotting showed that the transformed DS genecould be transcribed and highly expressed. High performance liquid chromatography (HPLC) analysisshowed that the dammarane-type sapogenin 20(S)-protopanaxadiol (PPD) content was 0.35–0.59 mg/gdw and the dammarane-type sapogenin 20(S)-protopanaxatriol (PPT) content was 0.23–0.43 mg/g dw inthe transgenic rice. LC/MS analysis confirmed production of PPD and PPT. These results indicate that anew “ginseng rice” germplasm containing dammarane-type sapogenins has been successfully developedby transforming the ginseng DS gene into rice.
