Abstract
In hairy root cultures of ginseng (Panax ginseng C.A. Meyer) transfonned by Agrobacterium rhizogenes, the effects of light, carbon source and various honnone on hairy root growth and anthocyanin production were investigated. Anthocyanin synthesis began to first occur 5 days after exposure to light, and then maximum yield of anthocyanin was 0.36 mg/g(fr wt) in MS medium after 30 days. Of the nutritional factors concentration of 60 mM nitrogen and sucrose as a carbon source showed marked effects on the growth and anthocyanin productiom MS medium supplemented with 0.5 mg/L IAA was most suitable for the hairy root proliferation, and the best accumulation of anthocyanin was obtained at 1 mg/L IAA treatment (0.41 mg/g, fr wt). Whereas 2,4-D tended to restrain the pigment synthesis. From the isolation and identification of anthocyanin pigments, main anthocyanin in ginseng hairy root was identified as pelargonidin-glucoside.coside.
Agrobacterium rhizogenes에 의하여 형질전환된 인삼 모상근을 배양하여 빛, 탄소원의 종류, 여러 가지 호르몬의 첨가가 모상근의 생장과 수용성 색소인 anthocyanin의 생산에 미치는 영향을 조사하였으며, 배양된 모상근으로부터 색소를 추출, 분리하여 anthocyanin을 동정하였다. 모상근을 광조건에서 배양하면 배양 5일 후부터 색소를 합성하였으며 배양 30일에 0.36mg/g(fr wt)의 색소를 생산하였다. 모상근의 배양시 총질소농도 60mM, 탄소원으로 sucrose가 모상근의 생장과 색소의 생산에 적합하였으며, 0.5mg/L IAA를 첨가하였을 때 모상근이 가장 빠르게 생장하였고 1 mg/L IAA를 첨가하였을 때 가장 높은 색소함량(0.41mg/g, fr wt)을 나타내었다. 그러나 2,4-D의 경우 모상근의 생장과 색소합성이 억제되는 경향을 보여주었다. 아울러 anthocyanin 색소를 분리, 동정한 결과 pelargonidin-glucoside로 확인되었다.
