  • Enzymes involved in triterpene synthesis
    Patent number: 7135624
    Abstract: This invention relates to an isolated nucleic acid fragment encoding an oxidosqualene cyclase. The invention also relates to the construction of a chimeric gene encoding all or a portion of the isolated polynucleotides of the invention, in sense or antisense orientation, operably linked to a suitable regulatory sequence.
    Type: Grant
    Filed: March 9, 2001
    Date of Patent: November 14, 2006
    Assignee: E. I. du Pont de Nemours and Company
    Inventors: Gregory T. Bryan, Brian McGonigle, Carl A. Maxwell
  • Pi-ta gene conferring fungal disease resistance to plants
    Patent number: 6479731
    Abstract: The preparation and use of an isolated nucleic acid fragment which confers a Pi-ta resistance gene-mediated defense response in plants against disease caused by fungal pathogens is described. Genes incorporating such nucleic acid fragments either alone or in combination with an AVR-Pita isolated nucleic acid fragment or functionally equivalent subfragments thereof and suitable regulatory sequences can be used to create transgenic plants which can produce a Pi-ta resistance gene-mediated defense response against a variety of fungal pathogens, in particular, the rice blast fungus.
