CA 2628263

The subject invention provides novel plants that are not only resistant to 2,4- D, but also to pyridyloxyacetate herbicides. Heretofore, there was no expectation or suggestion that a plant with both of these advantageous properties could be produced by the introduction of a single gene. 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-12 (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 pyridyloxyacétate. Auparavant, il n~existait aucun élément suggérant que l~introduction d~un seul gène permettrait la production d~une plante présentant ces deux propriétés avantageuses. L~invention concerne également des plantes qui produisent une ou plusieurs enzymes selon la présente invention ~superposées~ ensemble avec un ou plusieurs autres gènes de résistance aux herbicides. La présente invention permet de nouvelles combinaisons d~herbicides pour des usages nouveaux. En outre, la présente 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 préférés à utiliser selon la présente invention sont désignés dans le présent document sous le terme AAD-12 (AryloxyAlkanoate 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.
