Advances in Genetic Transformation of Panax Ginseng

HOU Chun-xi ZHAO Shou-jing LIANG Yan-long WANG Jian-hua(College of Biological and Agricultural Engineering,Jilin University,Changchun 130022,China)  
Genetic engineering is a powerful tool in Panax ginseng breeding.Genetic transformation and plant regeneration are the premise and foundation involved in genetic engineering of Panax ginseng.Ginseng can be regenerated through organogenesis or somatic embryogenesis and indirect somatic embryogenesis is mainly used for its regeneration.Summurized the factors influencing plant regeneration such as different explants,different carbohydrates,somatic embryo optimization and hormone-free approach.Ginseng transformation has been achieved by Agrobacterium tumefaciens and Agrobacterium rhizogenes and transgenic ginseng with good characters was obtained by introducing genes associated with biosynthesis of ginsenosides or herbicide gene.Hairy root culture system can supply large scale of ginsenosides,thus effect of rolC genes on ginseng hairy root induction,regeneration and bioreactor culture of hairy root were discussed.Additionally,problems that are present in genetic engineering of Panax ginseng were also discussed in this review.
