  • Publication number: 20240093214
    Abstract: Compositions and methods are provided for stacking multiple independent transgenic loci into the genome of a plant. Compositions include plants, seeds or plant cells comprising at least one transgenic target site and at least one genomic locus of interest integrated at different genomic sites within a genomic window. Plant breeding techniques can be employed such that the transgenic target site and the genomic locus of interest can be bred together. In this way, multiple independent transgene integrations can be generated within a genomic window to create a complex trait locus. The complex trait locus is designed such that the transgenic target sites and/or genomic loci of interest can segregate independently of each other, thus providing the benefit of altering a complex trait locus by breeding-in and breeding-away specific elements. Various methods can also be employed to modify the target sites such that they contain a variety of polynucleotides of interest.

  • Publication number: 20230323374
    Abstract: Compositions and methods are provided for genome modification of a target sequence in the genome of a plant or plant cell. The methods and compositions employ a guide RNA/Cas endonuclease system to provide an effective system for modifying or altering target sites within the genome of a plant, plant cell or seed. Also provided are compositions and methods employing a guide polynucleotide/Cas endonuclease system for genome modification of a nucleotide sequence in the genome of a cell or organism, for gene editing, and/or for inserting or deleting a polynucleotide of interest into or from the genome of a cell or organism. Once a genomic target site is identified, a variety of methods can be employed to further modify the target sites such that they contain a variety of polynucleotides of interest. Breeding methods and methods for selecting plants utilizing a two component RNA guide and Cas endonuclease system are also disclosed.

  • Publication number: 20230287521
    Abstract: Compositions and methods related to transgenic glyphosate tolerant Brassica plants are provided. Specifically, the present invention provides Brassica plants having a DP-073496-4 event which imparts tolerance to glyphosate. The Brassica plant harboring the DP-073496-4 event at the recited chromosomal location comprises genomic/transgene junctions within SEQ ID NO: 2 or with genomic/transgene junctions as set forth in SEQ ID NO: 12 and/or 13. The characterization of the genomic insertion site of the 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 event are provided.

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.
