  • Patent number: 7378499
    Abstract: Compositions and methods for protecting a plant from an insect pest are provided. The invention provides mutagenized nucleic acids that have been engineered to encode pesticidal polypeptides having increased resistance to proteolytic degradation by a plant protease. In particular, nucleic acid sequences encoding pesticidal polypeptides modified to comprise a proteolytic protection site that confers resistance to degradation or proteolytic inactivation by a plant protease are provided. Particular embodiments of the invention provide pesticidal polypeptide compositions and formulations, expression cassettes, and transformed plants, plant cells, and seeds. These compositions find use in methods for controlling pests, especially plant pests. Novel plant proteases, sequences encoding these proteases, and methods for their use are also provided.

  • Publication number: 20060288448
    Abstract: Compositions and methods for protecting a plant from an insect pest are provided. Nucleic acid molecules encoding insect protoxins or insect toxins modified to comprise at least one proteolytic activation site that is sensitive to an insect gut protease are provided. Cleavage of a modified insect protoxin at the proteolytic activation site by an insect gut protease produces an active insect toxin in the gut of the insect pest. Cleavage of a modified insect toxin of the invention at a proteolytic activation site results in the production of an active insect toxin in the insect gut that displays improved pesticidal activity relative to the insect toxin that lacks the proteolytic activation site. Methods of using the modified insect protoxin and modified insect toxin nucleic acid sequences and the polypeptides they encode to protect a plant from an insect pest are provided.

  • Patent number: 6978967
    Abstract: A fin deployment system for missiles and munitions that deploys and activates straight flat fins for roll control authority. The fin deployment system employs numerous design features, among which are the following: A wrap-around fin concept generates space-savings within a projectile body whereby the fins are arranged in a wrapped configuration around a boomtail structure. The fins may be constructed of a super-elastic material; the system eliminates mechanical means of deploying the wrapped fins, eliminating the need for springs to deploy the fins. The fin deployment achieves substantial space savings for increasing the onboard towing capacity of electronic packaging or lethality in the missiles and munitions systems, while at the same time providing a good roll control authority during flight by enabling a straight fin deployment resulting from the use of super-elastic materials.
