  • 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: 7928296
    Abstract: Compositions and methods related to transgenic glyphosate/ALS inhibitor-tolerant maize plants are provided. Specifically, the present invention provides maize plants having a DP-098140-6 event which imparts tolerance to glyphosate and at least one ALS-inhibiting herbicide. The maize plant harboring the DP-098140-6 event at the recited chromosomal location comprises genomic/transgene junctions having at least the polynucleotide sequence of SEQ ID NO:5 and/or 6. The characterization of the genomic insertion site of the DP-098140-6 event provides for an enhanced breeding efficiency and enables the use of molecular markers to track the transgene insert in the breeding populations and progeny thereof. Various methods and compositions for the identification, detection, and use of the maize DP-098140-6 events are provided.

  • Patent number: 5513508
    Abstract: An apparatus for inflating inflatable articles, such as bicycle tire inner tubes, and for securing mobile articles, such as bicycles, to other objects. In one preferred embodiment, a first length of cable and a second length of cable are kept within a housing until needed to secure the article to an object. A cable holding sleeve holds the lengths of cable in a substantially side-by-side relationship when the cables are within the housing. When needed, the lengths of cable are withdrawn from the housing, passed through the frame of the article, around the object and the two ends of the cables are locked together by way of, for example, a cylindrical combination lock. When the first and second lengths of cable are unlocked, a constant tension spring, provided in some embodiments, retracts the lengths of cable back into the housing. Other embodiments of the invention are provided with a pump piston at the end of the lengths of cable which remain within the housing.
