摘要
(US10167483)
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.

4. A method of controlling herbicide resistance in weeds in a field, wherein said method comprises applying to said weeds at least one herbicide selected from the group consisting of a pyridyloxy auxin herbicide and a phenoxy auxin herbicide, said field comprising a plurality of crop plants comprising the expression cassette of claim 1.
5. A method of selecting at least one transgenic plant that is resistant or tolerant to both phenoxy auxin and pyridyloxy auxin herbicides, said method comprising applying a herbicidically effective amount of an aryloxyalkanoate herbicide to a plurality of plants in a field, wherein said plurality of plants in said field comprises at least one plant that is stably transformed with the expression cassette of claim 1 and is able to grow in said effective amount of the aryloxyalkanoate herbicide, and identifying said plant that is stably transformed with said expression cassette.
6. The method of claim 4, wherein said plurality of crop plants are dicots.
7. The method of claim 6, wherein said dicots are selected from the group consisting of soybean plants, cotton plants, canola plants, sugar beet plants, tomato plants, and sunflower plants.
8. The method of claim 4, wherein said method comprises applying to said weeds at least one herbicide selected from the group consisting of a pyridyloxy auxin herbicide and a phenoxy auxin herbicide, and wherein said pyridyloxy auxin herbicide comprises one or more pyridyloxyacetate herbicides.
9. The method of claim 8, wherein said pyridyloxyacetate herbicide(s) is selected from the group consisting of triclopyr and fluroxypyr.
10. The method of claim 4, wherein said applying step comprises applying said herbicide to said crop plants within 14 days of planting a seed in said field, wherein said seed comprises an expression cassette comprising a polynucleotide operably linked to a heterologous plant promoter or a plant virus promoter, wherein said polynucleotide encodes a protein that catalyzes degradation of phenoxy auxin and pyridyloxy auxin herbicides, wherein the polynucleotide that encodes said protein comprises SEQ ID NO:3.
11. The method of claim 4, wherein said plurality of crop plants further comprises a second polynucleotide encoding a second protein that confers said crop plants with resistance to at least one other herbicide, wherein said second polynucleotide is heterologous, and said method further comprises applying said at least one other herbicide to least a portion of said field.
12. The method of claim 11, wherein said herbicides are applied sequentially or concurrently.
13. The method of claim 11, wherein said herbicides are applied from a tank mix.
14. The method of claim 11, wherein said at least one other herbicide is selected from the group consisting of acetochlor, acifluorfen, alloxydim, amidosulfuron, aminopyralid, atrazine, beflubutamid, bispyribac, butafenacil, cafenstrole, carfentrazone, chlorimuron, chlorotoluron, cinidon-ethyl, clethodim, clodinafop, clomazone, cloproxydim, clopyralid, cloransulam, cyanazine, cyclosulfamuron, cycloxydim, cyhalofop, daimuron, dicamba, diclofop, diclosulam, diflufenican, dimethenamid, diquat, dithiopyr, diuron, ethalfluralin, fenoxaprop, flazasulfuron, florasulam, fluazifop, flucarbazone, flufenacet, flufenican, flufenpyr, flumetsulam, flumiclorac, flumioxazin, fluroxypyr, fluthiacet, fomesafen, foramsulfuron, glufosinate, glyphosate, halosafen, halosulfuron, haloxyfop, imazamethabenz, imazamox, imazapic, imazapyr, imazaquin, imazethapyr, imazosulfuron, iodosulfuron, ioxynil, isoxaben, isoxaflutole, lactofen, linuron, mefenacet, mefluidide, mesosulfuron, mesotrione, metamifop, metazachlor, metosulam, metribuzin, MSMA, napropamide, nicosulfuron, norflurazon, oryzalin, oxadiazon, oxyfluorfen, paraquat, pebulate, pendimethalin, penoxsulam, picloram, picolinafen, pinoxaden, primisulfuron, profoxydim, propanil, pyraflufen, pyrazosulfuron, pyribenzoxim, pyriminobac, pyrithiobac, pyroxasulfone, pyroxsulam, quinclorac, quinmerac, quizalofop, rimsulfuron, sethoxydim, simazine, sulcotrione, sulfentrazone, sulfometuron, tefuryltrione, tembotrione, tepraloxydim, terbacil, thiazopyr, thidiazuron, thiencarbazone, thifensulfuron, thiobencarb, topramezone, tralkoxydim, triasulfuron, tribenuron, triclopyr, trifloxysulfuron, trifluralin, triflusulfuron, and tritosulfuron.
