Abstract
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, …
