  • Publication number: 20240392310
    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: 20190271004
    Abstract: Methods and compositions are provided which employ a silencing element that, when ingested by a pest, such as a pest from the Lepidoptera order, they are capable of decreasing 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 target polynucleotides encoding polypeptides from specific protein families and various target polynucleotides set forth in SEQ ID NOS: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, or 50 or active variants and fragments thereof, wherein a decrease in expression of one or more the sequences in the target pest controls the pest (i.e., has insecticidal activity).

  • Publication number: 20020112116
    Abstract: Methods of storing collections of related data in memory can include storing a first collection of related data in a first collection of tagged data pieces and storing a second collection of related data in a second collection of tagged data pieces. Each tagged data piece of the first collection can include a respective header including a first tag identification common to each of the tagged data pieces of the first collection and a fragment identification unique to each of the tagged data pieces of the first collection. Similarly, each tagged data piece of the second collection can include a respective header including a second tag identification common to each of the tagged data pieces of the second collection and a fragment identification unique to each of the tagged data pieces of the second collection wherein the first and second tag identifications are distinct. Related systems and computer program products are also discussed.
