  • Nematode-active toxin from a Bacillus thuringiensis isolate
    Patent number: 5322932
    Abstract: A novel B.t. gene encoding a toxin which is toxic to nematodes has been cloned from a B. thuringiensis microbe. The DNA encoding the B.t. toxin can be used to transform various prokaryotic and eukaryotic microbes to express the B.t. toxin. These recombinant microbes can be used to control nematodes in various environments.
    Type: Grant
    Filed: July 27, 1993
    Date of Patent: June 21, 1994
    Assignee: Mycogen Corporation
    Inventors: Kenneth E. Narva, George E. Schwab, Theresa Galasan, Jewel M. Payne
  • Hybrid diphtheria-B.t. pesticidal toxins
    Patent number: 5290914
    Abstract: The invention concerns novel hybrid pesticidal toxins. These toxins are expressed as the fusion protein of a chimeric gene. Specifically exemplified is a novel B.t. hybrid toxin. These novel toxins have increased toxicity against target pests. The invention also concerns a process for preparing a hybrid virus having an altered insect host range.
    Type: Grant
    Filed: April 28, 1988
    Date of Patent: March 1, 1994
    Assignee: Mycogen Corporation
    Inventors: Edward Wilcox, David L. Edwards, George E. Schwab, Mark Thompson, Paul Culver
  • Process for controlling lepidopteran pests
    Patent number: 5286485
    Abstract: The subject disclosure concerns Bacillus thuringiensis strains which can be used to control lepidopteran pests. The strains were previously known to control coleopteran pests. The discovery of lepidopteran activity was totally unexpected.These B.t. strains can be formulated using standard lepidopteran formulation procedures. Means of administration are also standard.The genes encoding lepidopteran-active toxins can be isolated from the B.t. isolates and used to transform other microbes for use to control lepidopteran pests.

  • Genes encoding nematode-active toxins cloned from bacillus thuringiensis isolate PS17
    Patent number: 5281530
    Abstract: Nematicidal .delta.-endotoxin encoding genes have been cloned from a novel Bacillus thuringiensis isolate known as B.t. PS17. These novel genes, designated B.t. PS17a, B.t. PS17b, Bt. PS17d, and B.t. PS17e, can be transferred to various microbial and plant hosts via known techniques. In the microbial or plant host, one or more of the genes of the invention can be used to express the novel nematicidal toxins to control susceptible nematodes.

  • Compositions and methods for the control of flukes
    Patent number: 5262399
    Abstract: Methods and compositions for the control of flukes are described. Specifically, Bacillus thuringiensis (B.t.) isolates having flukicidal activity are disclosed. Also described are recombinant hosts which express B.t. genes coding for flukicidal toxins. The B.t. isolates and recombinant proteins are shown to be useful in a method for controlling flukes including the liver fluke.

  • Universal and specific probes for Bacillus thuringiensis endotoxin genes
    Patent number: 5204237
    Abstract: This invention concerns novel gene probes which can be used to identify DNA from Bacillus thuringiensis microbes which encode insecticidally-active protein endotoxins. The invention probes greatly facilitate the search for useful microbes hosting genes which encode insecticidally-active toxins.

  • Bacillus thuringiensis gene encoding a coleopteran-active toxin
    Patent number: 5186934
    Abstract: A novel B.t. gene encoding a toxin which is toxic to coleopteran insects has been cloned from a coleopteran-active B. thurningiensis microbe. The DNA encoding the B.t. toxin can be used to transform various prokaryotic and eukaryotic microbes to express the B.t. toxin. These recombinant microbes can be used to control coleopteran insects in various environments.
