초록

A protocol for the production of transgenic Panax ginseng C.A. Meyer was established via Agrobacterium tumfaciens- mediated genetic transformation of direct somatic embryos. A number of conditions related to the co-cultivation were tested with respect to maximizing transformation efficiency. The results showed that pH of the co-cultivation medium (5.7), the bacterial growth phase (optical density; OD600 = 0.8), co-cultivation period (3 days), and acetosyringone concentration (100 μM) had positive effects on transformation. Selected plantlets were cultured on the medium at an elevated hygromycin level (30㎎/ℓ). Integration of the transgenes into the P. ginseng nuclear genome was confirmed by PCR analysis using hpt primers and by Southern hybridization using hpt-specific probe. The transgenic plantlets were obtained after 3-month cultivation and did not show any detectable variation in morphology or growth characteristics compared to wild-type plants.
