    • The present invention is directed generally to activating gene expression or causing over-expression of a gene by recombination methods in situ. The invention also is directed generally to methods for expressing an endogenous gene in a cell at levels higher than those normally found in the cell. In one embodiment of the invention, expression of an endogenous gene is activated or increased following integration into the cell, by non-homologous or illegitimate recombination, of a regulatory sequence that activates expression of the gene. The invention also provides methods for the identification, activation, isolation, and/or expression of genes undiscoverable by current methods since no target sequence is necessary for integration. The invention also provides methods for isolation of nucleic acid molecules (particularly cDNA molecules) encoding a variety of proteins. Thus, by the present invention, endogenous genes, including those associated with human disease and development, may be activated and isolated without prior knowledge of the sequence, structure, function, or expression profile of the genes.
    • 本发明一般涉及通过原位重组方法激活基因表达或引起基因过度表达。 本发明还通常涉及用于在细胞中以比通常在细胞中发现的那些更高的水平表达内源基因的方法。 在本发明的一个实施方案中,内源基因的表达在通过激活基因表达的调节序列的非同源或非法重组整合入细胞后被激活或增加。 本发明还提供了鉴定,激活,分离和/或表达不能被现有方法发现的基因的方法,因为不需要靶序列进行整合。 本发明还提供了分离编码多种蛋白质的核酸分子(特别是cDNA分子)的方法。 因此,通过本发明,可以在没有基因的序列,结构,功能或表达谱的事先知识的情况下激活和分离内源基因,包括与人类疾病和发育相关的内源基因。

    • The present invention discloses trichothecene-resistant transgenic plants, plant tissues, plant seeds, and plant cells comprising a heterologous polynucleotide encoding a gene product having tricothecene resistance activity that thereby confers trichothecene resistance to the transgenic plants, plant tissues, plant seeds, and plant cells. Trichothecene resistance activity, as used herein, refers to an activity that reduces or inhibits the phytotoxicity of a trichothecene, particularly to a fungus and/or plant. In a particular embodiment, trichothecene resistance activity refers to an activity that transfers an acetate to the C-3 position of a trichothecene such as T-2 toxin, HT-2 toxin, isotrichodermol, diacetoxyscirpenol (“DAS”), 3-deacetylcalonectrin, 3,15-dideacetylcalonectrin, scirpentriol, neosolaniol; 15-acetyldeoxynivalenol, nivalenol, 4-acetylnivalenol (fusarenone-X), 4,15-diacetylnivalenol, 4,7,15-acetylnivalenol, and deoxynivalenol (“DON”) and their various acetylated derivatives. In another particular embodiment, the gene product having trichthecene resistance activity is a 3-O-acetyltransferase from a trichothecene-producing species of Fusarium, such as Fusarium graminearum or Fusarium sporotrichioides.
    • 本发明公开了头孢霉烯抗性转基因植物,植物组织,植物种子和植物细胞,其包含编码具有三氯生物抗性活性的基因产物的异源多核苷酸,从而赋予转基因植物,植物组织,植物种子和植物细胞的单端孢霉烯抗性 。 如本文所用,三氯乙炔抗性活性是指减少或抑制单端孢霉烯特别是真菌和/或植物的植物毒性的活性。 在一个特定的实施方案中,单端孢霉烯抗性活性是指将乙酸酯转移到单端孢霉烯C-3位的活性,例如T-2毒素,HT-2毒素,异维甲酸,二乙酰氧基甲苯酚(“DAS”),3-脱乙酰基木聚糖, 3,15-二乙酰胆碱,顺丁三醇,新溶胶甘醇; 15-乙酰基过氧化雪腐镰刀菌烯醇,新戊烯醇,4-乙酰基雪腐镰刀菌烯醇(fisarenone-X),4,15-二乙酰基雪腐镰刀菌烯醇,4,7,15-乙酰基雪腐镰刀菌烯醇和脱氧雪腐镰刀菌烯醇(“DON”)及其各种乙酰化衍生物。 在另一个具体实施方案中,具有三辛抗性活性的基因产物是来自产生单端孢霉烯的镰刀菌属物种如禾谷镰刀菌(Fusarium graminearum)或孢子镰刀菌(Fusarium sporotrichioides)的3-O-乙酰转移酶。
