Abstract

The production of anthraquinone has been dectected in transformed roots of Rheum undulatum L. The effects of medium, initial pH, concentration of sucrose, light irradiation and elicitors on anthraquinone production in transformed roots of Rheum undulatum L. were investigated. The maximum production of anthaquinone was achieved in WPM medium (pH 5.7) supplemented with 6% sucrose, 0.5 mg/l $GA_3$, and 50 mg/l chitosan at 16h light $(16{\mu}mol\;m^{-2}s^{-1})$ condition. Under the optimum conditions, the production of anthraquinone reached to 0.18 mg/g(F.W.) after 8 weeks. The content was estimated about 1.3 times of the level of native roots.

대황(Rheum undulatum L.)의 형질전환된 뿌리의 기내(in vitro)배양으로부터 quinone계 알칼로이드 물질인 anthraquinone의 생산성을 확인하고자 하였다. 형질전환된 뿌리로부터 anthraquinone의 생산에 있어서 배지, 초기 pH, 탄소원의 농도, 광 그리고 elicitors의 영향을 조사 하였다. 형질전환된 뿌리는 6% sucrose와 0.5 mg/l $GA_3$ 그리고 50 mg/l chitosan이 첨가된 WPM 배지에 치상한 후 16/8의 광조건$(16{\mu}mol\;m^2s^1)$하에서 배양시 0.18 mg(생중량)의 anthraquinone의 생산성을 보여주었다. 이와같은 함량은 재배근의 약 1.3배에 해당된다.
