Title:
【発明の名称】植物培養における二次代謝産物生産の誘導方法及びその手段
Document Type and Number:
Japanese Patent JPH01500401
Kind Code:
A
Abstract:
Synthesis of alkaloids by suspension cultured Catharanthus roseus cells is enhanced by stressing the cultured cells osmotically by addition to the culture of such inducers as ionic osmotic stressors such as halide salts e.g. NaCl, KCl and FeCl3 or organic osmotic stressors such as sugar alcohols and sugar acids. Synthesis of alkaloids is also enhanced by addition of anti-gibberellin compounds and other compounds such as abscissic acid which is a plant growth regulator. Yields of alkaloids are consequently increased.
