Modulation of differential gene expression and change of polyamine content by salt stress are analyzed for the first time in a well-known medicinal plant, Panax ginseng C.A. Meyer. Three ginseng genes (PgSPD, PgSAMDC, and PgADC) involved in polyamine biosynthesis showed differential up-regulation patterns after 1 and 7 days of salt treatments. The(More)
The regulation of reactive oxygen scavengers against biotic and abiotic conditions were investigated in the seedling of Panax ginseng C. A. Meyer. From the EST library we selected the antioxidant marker genes such as superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), glutathione peroxidase (GPX), and glutathione synthase (GS). The(More)
In different plant species, secondary metabolite biosynthesis is regulated by the phytohormone jasmonic acid (JA), which is derived by the action of lipoxygenase. In this study, we examined mono- and sesquiterpenoid accumulation and the related signal transduction pathways and biosynthetic genes in adventitious root cultures of Panax ginseng C.A. Meyer as(More)
The effect of exogenously applied hydrogen peroxide on salt stress tolerance was investigated in Panax ginseng. Pretreatment of ginseng seedlings with 100 μM H2O2 increased the physiological salt tolerance of the ginseng plant and was used as the optimum concentration to induce salt tolerance capacity. Treatment with exogenous H2O2 for 2 days significantly(More)
