    摘要： Chemically inducible promoters are described that may be used to transform plants, including tobacco and lettuce, with genes which are easily regulatable by adding the 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 promoters described are ones that are inducible by a glucocorticoid or estrogen which is not endogenous to plants. Such promoters may be used with a variety of genes such as ipt, CKI1, or knotted1, to induce shoot formation in the presence of an appropriate inducer. The promoters may be used with genes which induce somatic embryos such as Lec1 or SERK to prepare somatic embryos which can be grown into seedlings and then into plants. 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.

    摘要： The present invention relates to methods for promoting somatic embryogenesis from a tissue or organ of a plant, by overexpressing a Wuschel gene in said tissue or organ. In one embodiment, such overexpression can be used as a silent selectable marker for transgenic plants. In another embodiment, such expression can be used to confer apomixis to a plant. In another embodiment, such overexpression can be used to create haploid plants, which can be used to produce dihaploid plants.

    摘要： 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.
