  • Publication number: 20130288898
    Abstract: Methods and compositions are provided related to improved plants that are tolerant to more than one herbicide. Particularly, the invention provides plants that are tolerant of glyphosate and are tolerant to at least one ALS inhibitor, and methods of use thereof. The glyphosate/ALS inhibitor-tolerant plants comprise a polynucleotide that encodes a polypeptide that confers tolerance to glyphosate and a polynucleotide that encodes an ALS inhibitor-tolerant polypeptide. In specific embodiments, a plant of the invention expresses a GAT polypeptide and an HRA polypeptide. Methods to control weeds, improve plant yield, and increase transformation efficiencies are provided.

  • Patent number: 8367895
    Abstract: Methods and compositions are provided which employ a silencing element that, when ingested by a pest, 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. Target polynucleotides for specific protein classes and target polynucleotides set forth in SEQ ID NOS:1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or active variants or fragments thereof are provided, wherein a decrease in expression of one or more sequences in the target pest controls the pest. Further provided are silencing elements which when ingested by the pest decrease the level of the target polypeptide and thereby control the pest. Plants, plant part, bacteria and host cells comprising the silencing elements or an active variant or fragment thereof are also provided.

  • Publication number: 20110301223
    Abstract: Methods and compositions are provided which employ a silencing element that, when ingested by a pest, such as a Pentatomidae plant pest or a N. viridula, Acrosternum hilare, Piezodorus guildini, and/or Halymorpha halys 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: 1-292 or 302-304 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). 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 embodiment, the pest is Pentatomidae.

  • Patent number: 8071736
    Abstract: Compositions and methods for protecting a plant from an insect pest are provided. In particular, nucleic acid sequences encoding insect protoxins modified to comprise at least one proteolytic activation site that is sensitive to a plant protease or an insect gut protease are provided. Cleavage of the modified protoxin at the proteolytic activation site by a protease produces an active insect toxin. Methods of using the modified insect protoxin nucleic acid sequences and the polypeptides they encode to protect a plant from an insect pest are provided. Particular embodiments of the invention further provide modified insect protoxin compositions and formulations, expression cassettes, and transformed plants, plant cells, and seeds.
