  • Patent number: 9062284
    Abstract: 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).

  • Publication number: 20150080218
    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.

  • Patent number: 7838733
    Abstract: The subject invention provides novel plants that are not only resistant to 2,4-D and other phenoxy auxin herbicides, but also to aryloxyphenoxypropionate 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 alone or “stacked” together with another herbicide resistance gene, preferably a glyphosate resistance gene, so as to provide broader and more robust weed control, increased treatment flexibility, and improved herbicide resistance management options. More specifically, preferred enzymes and genes for use according to the subject invention are referred to herein as AAD (aryloxyalkanoate dioxygenase) genes and proteins. No ?-ketoglutarate-dependent dioxygenase enzyme has previously been reported to have the ability to degrade herbicides of different chemical classes and modes of action.

  • Publication number: 20080102079
    Abstract: This invention pertains in part to the development of a vaccine for poultry against necrotic enteritis (NE). The vaccine utilizes a protective antigen that is a mutated, full-length, non-toxic Clostridium perfringens (Cp) ?-toxin protein (Mcpa). Utility of this vaccine was demonstrated by reduction of lesion severity in NE challenge trails, for example. Also disclosed herein are novel approaches for producing this vaccine in significant quantities. One exemplified approach involves producing NE vaccine (mutated alpha toxin) in bacterial expression systems, preferably utilizing the Pseudomonas fluorescens system, for commercial use in controlling NE in the poultry industry. The subject vaccines can be administered preferably to chickens in several different ways. A novel, Type VI alpha toxin from chicken isolates of Cp is also disclosed.

  • Publication number: 20080019914
    Abstract: The subject invention provides unique biological alternatives for pest control. More specifically, the present invention relates to novel pesticidal proteins, novel sources of pesticidal proteins, polynucleotides that encode such toxins, and to methods of using these toxins to control insects and other plant pests. The subject invention relates to the surprising discovery that Paenibacillus species, and proteins therefrom, have toxicity to lepidopterans. There have been no known reports of a Paenibacillus species, strain, or protein having toxicity to lepidopterans. This is also the first known example of a Paenibacillus Cry protein that is toxic to lepidopterans. Furthermore, this is the first known report of a Paenibacillus having toxin complex (TC)-like proteins. The DAS1529 isolate disclosed here is also the first known example of a natural bacterium that produces both a Cry toxin and TC proteins. The subject invention also relates to new classes of Cry and TC proteins that are pesticidally active.

  • Publication number: 20060205653
    Abstract: The subject invention provides exciting new sources for surprising, new types of toxin complex (“TC”) proteins. The subject invention includes these new classes and types of TC proteins. The subject invention also includes polynucleotides that encode the subject proteins. The subject invention further provides vectors and cells comprising these polynucleotides. The subject invention also provides novel methods of controlling insects. The subject invention relates in part to the surprising discovery that new types of TC proteins can be obtained from a widely diverse phylogenetic spectrum of organisms including, most notably and surprisingly, eukaryotic fungus.

  • Publication number: 20060168683
    Abstract: The subject invention relates to insecticidal toxin complex (“TC”) fusion proteins and to polynucleotides that encode these fusion proteins. The subject invention also includes polynucleotides that encode the subject TC fusion proteins, and vectors comprising said polynucleotides. In some embodiments, the invention provides a fusion protein comprising a Class A protein, a Class B protein, and a Class C TC protein fused together to form a single protein. In some other embodiments, the invention provides a fusion protein comprising a Class B and a Class C TC proteins fused together. In the latter embodiments, the BC or CB fusion protein can be used to enhance or potentiate the anti-insect activity of a “Toxin A” or Class A protein. Heretofore, there was no expectation that such fusion proteins would properly function and retain their activity when fused together. The subject invention advantageously reduces the number of genes needed to transform plants.

  • Publication number: 20050102713
    Abstract: The present invention provides methods, vectors and gene constructs for enhancing expression of a recombinant nucleic acid sequence in transgenic plants and plant tissues. According to the present invention, nucleic acid sequences are obtained and/or derived from the 5? and 3? untranslated regions of genes encoding osmotin proteins and engineered to flank respective portions of a selected coding region of a vector. The vector construct may be introduced into plants and/or plant tissues through conventional procedures, resulting in enhanced expression of the selected coding region. In a preferred embodiment, the selected coding region is a chimeric gene or gene fragment expressing one or more proteins known to impart a level of insecticidal activity to a transgenic plant and/or plant tissue.
