Abstract: 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.

Abstract: This invention relates in part to soybean event pDAB8264.44.06.1 and includes a novel expression cassettes and transgenic inserts comprising multiple traits conferring resistance to glyphosate, aryloxyalkanoate, and glufosinate herbicides. This invention also relates in part to methods of controlling resistant weeds, plant breeding and herbicide tolerant plants. In some embodiments, the event sequence can be “stacked” with other traits, including, for example, other herbicide tolerance gene(s) and/or insect-inhibitory proteins. This invention further relates in part to endpoint TAQMAN® PCR assays for the detection of Event pDAB8264.44.06.1 in soybeans and related plant material. Some embodiments can perform high throughput zygosity analysis of plant material and other embodiments can be used to uniquely identify the zygosity of and breed soybean lines comprising the event of the subject invention. Kits and conditions useful in conducting these assays are also provided.
