  • Patent number: 6881539
    Abstract: A method for the rapid isolation and identification of the DNA sequence of transposable element-tagged genes is provided. The method comprises a modified AFLP approach using a transposable element-anchored amplification to identify and clone an amplification product that is associated with a mutant phenotype. Once cloned, the amplification product of interest may be used to screen a cDNA library directly or may be sequenced and compared to available databases for sequence homology. A modification of this approach provides a method for the identification of the location of an additional type of insertion event into genomic DNA, more specifically transgene insertion into the genome of a host organism.

  • Publication number: 20040133941
    Abstract: The invention features a method for identifying a gene associated with a desired phenotype. This method includes the steps of: (a) providing a plurality of cell cultures that include plant, animal, or fungal cells capable of exhibiting a desired phenotype; (b) contacting each of at least a subset of said cells with a stimulus that (i) induces said cells to exhibit the phenotype, or (ii) does not induce said cell cultures to exhibit the phenotype; (c) determining the presence of the phenotype in the cell cultures of step (b); and (d) identifying a gene having increased expression in response to stimuli that induce the phenotype but do not have increased expression in response to stimuli that do not induce the phenotype.

  • Publication number: 20040083500
    Abstract: Methods and compositions for the stacking of multiple nucleotide sequences at precise locations in the genome of a plant or plant cell are provided. Specifically, transfer cassettes comprising nucleotide sequences of interest flanked by non-identical recombination sites are introduced into a plant comprising a target site. The target site contains at least a set of non-identical recombination sites corresponding to those on the transfer cassette. Exchange of the nucleotide sequences flanked by the recombination sites is effected by a recombinase. The transfer cassettes and target sites are designed so as to allow for the stacking or ordering of nucleotide sequences at precise locations in the plant genome.

  • Patent number: 6670189
    Abstract: Methods for identifying organisms capable of degrading fumonisin. Fumonisin can be incorporated into culture medium for selection of organisms resistant to fumonisin and/or capable of growing on fumonisin as a sole carbon source. Using this method, several organisms have been identified. These organisms can be used to isolate the enzymes and the genes responsible for conferring fumonisin-resistance. The gene can be cloned and inserted into a suitable expression vector so that the protein can be further characterized. Additionally, the DNA encoding for fumonisin degrading enzymes can be used to transform plant cells normally susceptible to Fusarium or other toxin-producing fungus infection. Plants can be regenerated from the transformed plant cells. In this way, a transgenic plant can be produced with the capability of degrading fumonisin, as well as with the capability of producing the degrading enzymes.

  • Publication number: 20030226160
    Abstract: Methods to find optimal integration sites within a plant genome are provided. More particularly, a plant is transformed with a target site having an expression cassette comprising a nucleotide sequence operably linked to a promoter active in the plant. The target site is flanked by non-identical recombination sites. Transformed protoplast, tissues, or whole plants can be tested to determine the levels of activity of the inserted gene. By comparison of cellular activities of the gene in different insertion sites, preferred integration sites may be found wherein the gene is expressed at high or acceptable levels. These plants can then be utilized with subsequent retargeting techniques to replace the nucleotide sequence with other genes or nucleotide sequences of interest contained in a transfer cassette.
