PROBLEM TO BE SOLVED: To rationally switch a metabolism flow of a secondary metabolite that a plant cultured cell inherently has to the production of a new exogenous secondary metabolite.SOLUTION: A transgenic plant cultured cell is introduced with an exogenous secondary metabolism biosynthetic gene comprising a metabolic intermediate of a secondary metabolite produced by a plant cultured cell as a substrate.COPYRIGHT: (C)2014,JPO&INPIT【課題】植物培養細胞が本来有する二次代謝物の代謝フローを、合理的に新たな外来二次代謝物の産生へとスイッチングさせることを目的とする。【解決手段】植物培養細胞が産生する二次代謝産物の代謝中間体を基質とする外来二次代謝生合成遺伝子を導入したことを特徴とする。【選択図】 図7
