  • Patent number: 11959085
    Abstract: The present disclosure provides compositions and methods for regulating expression of heterologous nucleotide sequences in a plant. Compositions include a novel nucleotide sequence for regulatory elements from Lamium Leaf Distortion Associated Virus. A method for expressing a heterologous nucleotide sequence in a plant using the regulatory element sequences disclosed herein is provided. The method comprises transforming a plant or plant cell with a nucleotide sequence operably linked to one of the regulatory elements of the present disclosure.

  • Publication number: 20240002842
    Abstract: Methods and compositions are provided which employ a silencing element that, when ingested by a pest, such as a Coleopteran plant pest or a Diabrotica plant pest, decrease the expression of a target sequence in the pest. In specific embodiments, the decrease in expression of the target sequence controls the pest and thereby the methods and compositions are capable of limiting damage to a plant. The present invention provides various target polynucleotides set forth in any one of SEQ ID NOS: disclosed herein, (but not including the forward and reverse primers.) or active variants and fragments thereof, or complements thereof, wherein a decrease in expression of one or more of the sequences in the target pest controls the pest (i.e., has insecticidal activity). Further provided are silencing elements which when ingested by the pest decrease the level of the target polypeptide and thereby control the pest. In specific embodiments, the pest is D. virgifera virgifera, D. barberi, D. virgifera zeae, D. speciosa, D.

  • Publication number: 20220340620
    Abstract: Compositions and methods for controlling pests are provided. The methods involve transforming organisms with a nucleic acid sequence encoding an insecticidal protein. In particular, the nucleic acid sequences are useful for preparing plants and microorganisms that possess insecticidal activity. Thus, transformed bacteria, plants, plant cells, plant tissues and seeds are provided. Compositions are insecticidal nucleic acids and proteins of bacterial species. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest including plants, as probes for the isolation of other homologous (or partially homologous) genes. The pesticidal proteins find use in controlling, inhibiting growth or killing Lepidopteran, Coleopteran, Dipteran, fungal, Hemipteran and nematode pest populations and for producing compositions with insecticidal activity.

  • Publication number: 20220119830
    Abstract: The invention relates to gene expression regulatory sequences, specifically introns that act as enhancers of gene expression, the promoter and terminator sequences endogenously associated with these introns. Presence of these intronic enhancer sequences in proximity to promoter sequences leads to enhancement of gene expression. Methods of finding such new intronic enhancer sequences and using them to generate transgenic plants are also described.
