摘要： Methods and constructs for the introduction of multiple genes encoding enzymes in a multi-enzyme biosynthetic pathway are provided. In one embodiment, the constructs contain two or more enzyme-encoding genes, each under the control of an inducible promoter and each with a polyadenylation signal. The constructs are used to produce transgenic plants, in which the expression of the enzymes are increased when a chemical inducing agent is applied, and a biosynthetic product of the series of enzymes encoded by the transgenes is produced. Constructs may be used which contain two or more enzyme-encoding genes under the control of one or more promoters activated by activator molecules or complexes expressed from a transgene or transgenes, which are themselves under the control of one or more inducible promoters and switched on following the external application of a chemical. The transgene or transgenes expressing the activator molecules or complexes may be included in the same construct containing multiple genes encoding enzymes in a multi-enzyme biosynthetic pathway. Alternatively, the transgene or transgenes expressing the activator molecules or complexes may be on a different construct from the construct containing multiple genes encoding enzymes in a multi-enzyme biosynthetic pathway. The activator molecule can be expressed using a constitutive promoter in an inactive form which is converted to the active form following application of the chemical inducing agent.
摘要翻译： 提供了在多酶生物合成途径中引入编码酶的多个基因的方法和构建体。 在一个实施方案中，构建体含有两个或更多个酶编码基因，每个基因在诱导型启动子的控制下并且各自具有多聚腺苷酸化信号。 构建体用于产生转基因植物，其中当施用化学诱导剂时酶的表达增加，并且产生由转基因编码的一系列酶的生物合成产物。 可以使用含有两个或更多个酶编码基因的构建体，所述两个或多个酶编码基因在一个或多个由活化剂分子或由转基因或转基因表达的复合物所激活的启动子的控制下，所述启动子本身处于一个或多个诱导型启动子的控制下， 化学品的外部应用。 表达活化剂分子或复合物的转基因或转基因可以包含在含有多酶生物合成途径中的酶的多个基因的相同构建体中。 或者，表达活化剂分子或复合物的转基因或转基因可以与含有多酶生物合成途径中的酶的多个基因的构建体在不同的构建体上。 可以使用非活性形式的组成型启动子来表达活化剂分子，其在施用化学诱导剂后转化为活性形式。
