Patent

CA 2686835

The subject invention provides novel plants that are not only resistant to 2,4-D, but also to a pyridyloxyacetate herbicide. The subject invention also includes plants that produce one or more enzymes of the subject invention "stacked" together with one or more other herbicide resistance genes. The subject invention enables novel combinations of herbicides to be used in new ways. Furthermore, the subject invention provides novel methods of preventing the development of, and controlling, strains of weeds that are resistant to one or more herbicides such as glyphosate. The preferred enzyme and gene for use according to the subject invention are referred to herein as AAD-13 (AryloxyAlkanoate Dioxygenase). This highly novel discovery is the basis of significant herbicide tolerant crop trait and selectable marker opportunities.

La présente invention concerne de nouvelles plantes qui sont non seulement résistantes au 2,4-D mais aussi aux herbicides à base de pyridyloxyacétate. L'invention concerne également des plantes qui produisent selon l'invention une ou plusieurs enzymes "superposées" avec un ou plusieurs autres gènes de résistance aux herbicides. L'invention permet de nouvelles combinaisons d'herbicides pour des usages nouveaux. En outre, l'invention concerne de nouveaux procédés pour la prévention du développement, et le contrôle, de souches de mauvaises herbes résistantes à un ou plusieurs herbicides, comme le glyphosate. L'enzyme et le gène privilégiés à utiliser selon la présente invention sont désignés dans le présent document sous le terme AAD-13 (Aryloxyalcanoate Dioxygénase). Cette découverte très novatrice est le fondement d'opportunités importantes concernant la caractéristique de résistance aux herbicides des cultures et le gène de sélection.
