  • Patent number: 11104914
    Abstract: The present disclosure provides compositions and methods utilizing double strand ribonucleic acid (dsRNA) to control insects, including whiteflies. More particularly, the present invention relates to several specific synthetic dsRNAs that induce RNA interference (RNAi) in the target insects and methods of delivering the dsRNAs to them, such as allowing feeding on plants treated with, or transgenically expressing, the dsRNAs.
    Type: Grant

  • Patent number: 11001842
    Abstract: The current disclosure provides for peptide-conjugated phosphorodiamidate morpholino oligomers (PPMOs) antisense oligonucleotides that target plant pathogens and insect pests by targeting the microbes within the insect pest. Methods of delivering PPMOs to bacteria in plants, in insect carriers, and to the insects via plant feeding are also provided.

  • Publication number: 20200010840
    Abstract: Herein is disclosed synthetic oligonucleotides comprising 2?F-ANA nucleosides that can be utilized to control plant-chewing and phloem-feeding insects, bacteria present in such insects, and bacteria present in plants. The novel approaches and materials provided herein allow for reduction of pesticide and antibiotic use without the need to create genetically modified plants.

  • Patent number: 10344291
    Abstract: dsRNA generated from D. citri trehalase gene is effective in reducing fitness and/or survival of D. citri. Thus genetically altered plants expressing the dsRNA and plants to which dsRNA solutions are applied increase D. citri mortality and reduce D. citri infestation. With reduced D. citri population, the spread of microorganisms for which D. citri is a vector is reduced. Such microorganisms include, but are not limited to, C. Liberibacter species, including: CLas, CLam, and CLaf. Thus, applying of the D. citri trehalase dsRNA to a plant reduces disease and/or microorganism transmission by killing D. citri that feed on the treated plant.

  • Publication number: 20180023076
    Abstract: The present disclosure provides compositions and methods of delivering double strand ribonucleic acid (dsRNA) to insects that penetrate plant tissues to feed on sap and other liquid components of plants. Taking advantage of the liquid transport capabilities of plant vascular structures, dsRNA is provided to plant tissues in an aqueous solution that is then transported throughout the tissues. The dsRNA-laden plant material is then presented to insects that can ingest the dsRNA by feeding on the plant tissue.

  • Patent number: 7294758
    Abstract: The subject invention pertains to materials and methods for producing plants that are resistant to infection by geminiviruses and other related viruses. Methods of the invention comprise transforming a plant with a polynucleotide wherein when the polynucleotide is expressed in the plant, the transformed plant exhibits resistance to plant viral infections. Exemplified herein is the use of a polynucleotide encoding a Rep protein derived from tomato mottle geminivirus. The methods of the invention can be used to provide resistance to viral infection in plants such as tomato and tobacco. The present invention also concerns transformed and transgenic plants in plant tissue that express a polynucleotide encoding a plant virus Rep protein, or a fragment or variant thereof.
