    • Disclosed is a chemically inducible promoter for transforming plants or plant cells with genes which are regulatable by adding the plants or cells to a medium containing an inducer or by removing them from such medium. The promoter is inducible by a glucocorticoid, estrogen or inducer not endogenous to plants. Such promoters may be used with any plant genes that can promote shoot regeneration and development to induce shoot formation in the presence of a glucocorticoid, estrogen or inducer. The promoter may be used with antibiotic or herbicide resistance genes or other genes which are regulatable by the presence or absence of a given inducer. Also presented are organisms or cells comprising a gene wherein the natural promoter of the gene is disrupted and the gene is placed under the control of a transgenic inducible promoter. These organisms and cells and their progeny are useful for screening for conditional gain of function and loss of function mutations.
    • 公开了一种化学诱导型启动子,用于通过将植物或细胞添加到含有诱导物的培养基中或通过从这种培养基中除去可调节基因来转化植物或植物细胞。 启动子可通过糖皮质激素,雌激素或对植物无内源性的诱导物诱导。 这样的启动子可以与任何植物基因一起使用,所述植物基因可以在糖皮质激素,雌激素或诱导物的存在下促进芽再生和发育以诱导芽形成。 启动子可以与抗生素或除草剂抗性基因或其它可通过给定诱导物的存在或不存在而调节的基因一起使用。 还提供了包含基因的生物体或细胞,其中基因的天然启动子被破坏并且将基因置于转基因诱导型启动子的控制下。 这些生物和细胞及其后代可用于筛选功能条件增加和功能突变丧失。

    • A chemically inducible promoter is described which may be used to transform plants with genes which are easily regulatable by adding plants or plant cells to a medium containing an inducer of the promoter or by removing the plants or plant cells from such medium. The promoter described is one which is inducible by a glucocorticoid which is not endogenous to plants. Such promoters may be used with a variety of genes such as ipt or knottedl to induce shoot formation is the presence of a glucocorticoid. The promoter may also be used with antibiotic or herbicide resistance genes which are then regulatable by the presence or absence of inducer rather than being constitutive. Other examples of genes which may be placed under the control of the inducible promoter are also presented.
    • 描述了一种化学诱导型启动子,其可用于通过将植物或植物细胞添加到含有启动子诱导剂的培养基的培养基中或通过从该培养基中除去植物或植物细胞而使易于调节的基因转化植物。 描述的启动子是由植物不是内源性的糖皮质激素诱导的。 这样的启动子可以与各种基因如ipt或knotted1一起使用以诱导芽形成是糖皮质激素的存在。 启动子也可以与抗生素或除草剂抗性基因一起使用,然后通过存在或不存在诱导剂而不是组成型的基因。 还可以列举可置于诱导型启动子控制下的基因的其它实例。
