  • Publication number: 20130263324
    Abstract: Methods for producing in a plant a complex transgenic trait locus comprising at least two altered target sequences in a genomic region of interest are disclosed. The methods involve the use of two or more double-strand-break-inducing agents, each of which can cause a double-strand break in a target sequence in the genomic region of interest which results in an alteration in the target sequence. Also disclosed are complex transgenic trait loci in plants. A complex transgenic trait locus comprises at least two altered target sequences that are genetically linked to a polynucleotide of interest. Plants, plant cells, plant parts, and seeds comprising one or more complex transgenic trait loci are also disclosed.

  • Publication number: 20130252242
    Abstract: Compositions and methods related to transgenic glyphosate/ALS inhibitor-tolerant soybean plants are provided. Specifically, soybean plants having a 3560.4.3.5 event which imparts tolerance to glyphosate and at least one ALS-inhibiting herbicide are provided. The soybean plant harboring the 3560.4.3.5 event at the recited chromosomal location comprises genomic/transgene junctions having at least the polynucleotide sequence of SEQ ID NO:10 and/or 11. The characterization of the genomic insertion site of the 3560.4.3.5 event provides for an enhanced breeding efficiency and enables the use of molecular markers to track the transgene insert in the breeding populations and progeny thereof. Various methods and compositions for the identification, detection, and use of the soybean 3560.4.3.5 events are provided.

  • Publication number: 20130014294
    Abstract: A targeting method is described that allows precise cassette replacement at a previously characterized genetic locus. A target DNA construct containing a pair of incompatible FRT sites flanking a target cassette was introduced into soybean by regular biolistic transformation. Transgenic events containing a single complete copy of the target site were then selected and retransformed with a donor DNA construct containing the identical pair of incompatible FRT sites flanking a donor cassette. Precise DNA cassette exchange happened between the target cassette and the donor cassette via recombinase mediated cassette exchange (RMCE) so that the donor cassette was introduced at the exact genomic site previously occupied by the target cassette. Through repeated RMCE using additional incompatible FRT sites, multiple groups of transgenes can be stacked at the same genomic locus.
