  • Spinosyn-producing polyketide synthases
    Patent number: 7626010
    Abstract: The invention provides, biologically active spinosyns, hybrid spinosyn polyketide synthases capable of functioning in Saccharopolyspora spinosa to produce the spinosyns, and methods of controlling insects using the spinosyns.
    Type: Grant
    Filed: October 20, 2005
    Date of Patent: December 1, 2009
    Assignee: Dow AgroSciences LLC

  • Whisker-mediated transformation of embryogenic cotton suspension cultures
    Patent number: 7166768
    Abstract: Embryogenic cotton suspension cultures can be transformed by elongated, needle-like structures called “whiskers”. The process comprises the agitation of cotton suspension cultures in the presence of DNA and whiskers, whereby DNA uptake and integration thereof is facilitated.
    Type: Grant

  • DNA Sequences from
    Patent number: 7161062
    Abstract: Nucleotide sequences for two genes, tcdB and tccC2, from the tcd genomic region of Photorhabdus luminescens W-14 are useful in heterologous expression of orally active insect toxins.
    Type: Grant
    Filed: August 26, 2003
    Date of Patent: January 9, 2007
    Assignee: Wisconsin Alumni Research Foundation
    Inventors: Richard H. Ffrench-Constant, David J. Bowen, Thomas A. Rocheleau, Nicholas R. Waterfield
  • DNA encoding SPNF of the spinosyn cluster
    Patent number: 7015001
    Abstract: Spinosyn biosynthetic genes from Saccharopolyspora spinosa, spinosyn producing microorganisms transformed with the biosynthetic genes, methods using the biosynthetic genes to increase production of spinosyn insecticidal macrolides, and methods using the genes or fragments thereof to change the products produced by spinosyn-producing microorganisms are provided.
