  • Publication number: 20040092018
    Abstract: The inventon provides a method for producing a library of genetic mutations in a cell population by insertional mutagenesis, wherein a viral vector comprising a transposon is used to deliver said transposon to said cell population, which cell population stably expresses the cognate transposase for said transposon, and the transposon is mobilised to give a rise to the genetic mutations.

  • Publication number: 20040003429
    Abstract: The present invention provides a method for controlling a population of target pests, comprising: a) providing gene comprising a coding sequence encoding one constituent of an enzyme/pro-pesticide system and a promoter capable of driving the coding sequence in the target plants or vertebrate host; b) transforming the target plant or vertebrate with the gene; and c) administering to the transformed population of target plant or vertebrates the remaining constituents of the enzyme/pro-pesticide system such that inactive pro-pesticide is converted to active pesticide on or within the transformed plant or vertebrate host leading to the death of any invading population of target pests.

  • Publication number: 20020194634
    Abstract: A method for controlling a population of target insects comprising providing a gene comprising a coding sequence encoding one constituent of an enzyme/pro-pesticide system and a regulatory region operatively linked to said coding sequence. The regulatory region of the present invention regulates expression of said coding sequence in a target insect of said population of target insects in a sex specific manner. The method of the present invention further comprises transforming a plurality of said target insects with said gene, and allowing said gene to spread within the target insect population. The method further comprises administering to said population of target insects the remaining constituent(s) of said enzyme/pro-pesticide system wherein said enzyme catalyzes the conversion of the pro-pesticide to a pesticide.
