Panax ginseng is a well-known herbal plant originated from North-east asia for its various tonic effects. However, production of ginseng roots takes long time in field condition, usually five through six years until harvest. Additionally, ginseng is very susceptible to many kinds of biotic and abiotic stresses, for example, Rhizoctonia solani, which causes damping-off, or high temperature. To overcome these limits, induction of adventitious roots has been studied for more than 10 years and also adventitious roots are widely used materials for genetic research of P.ginseng. In this study, we induced adventitious roots from registered Korean ginseng cultivars and cultured them in bioreactor condition. Induction rate of adventitious roots from nine Korean ginseng cultivars was evaluated and growth pattern of four cultivars in bioreactor scale was also studied. Furthermore, genes that are related to biosynthesis of saponins in ginseng, ginsenoside, were discovered in ginseng whole-genome shotgun sequences for genetic research.
