  • Publication number: 20150064708
    Abstract: The present disclosure provides methods for detecting and identifying plant events that contain precision targeted genomic loci, and plants and plant cells comprising such targeted genomic loci. The method can be deployed as a high throughput process utilized for screening a donor DNA polynucleotide insertion at the targeted genomic loci. The methods are readily applicable for the identification of plant events produced via a targeting method which results from the use of a site specific nuclease.

  • Patent number: 8916752
    Abstract: The subject invention provides novel plants that are not only resistant to 2,4-D, but also to pyridyloxyacetate herbicides. Heretofore, there was no expectation or suggestion that a plant with both of these advantageous properties could be produced by the introduction of a single gene. The subject invention also includes plants that produce one or more enzymes of the subject invention “stacked” together with one or more other herbicide resistance genes. The subject invention enables novel combinations of herbicides to be used in new ways. Furthermore, the subject invention provides novel methods of preventing the development of, and controlling, strains of weeds that are resistant to one or more herbicides such as glyphosate. The preferred enzyme and gene for use according to the subject invention are referred to herein as AAD-12 (AryloxyAlkanoate Dioxygenase). This highly novel discovery is the basis of significant herbicide tolerant crop trait and selectable marker opportunities.

  • Patent number: 8581036
    Abstract: A method of introducing a molecule of interest into a plant cell having a cell wall includes interacting a gamma-zein peptide with a molecule of interest to form a gamma-zein linked structure. The gamma-zein linked structure is then placed in contact with the plant cell having a cell wall, and allowing uptake of the gamma-zein linked structure into the plant cell. Alternatively, a gene of interest can be expressed in a plant cell having an intact cell wall by interacting a gamma-zein peptide with the gene of interest to form a gamma-zein linked gene structure, allowing uptake of the gamma-zein linked gene structure into the plant cell, and expressing the gene of interest in the plant cell and its progeny.
