  • Patent number: 8653327
    Abstract: Methods for introducing a linear nucleic acid molecule of interest into a cell comprising a cell wall include use of nanoparticles coated with polyethylene glycol. In some embodiments, the cell comprising a cell wall is a plant cell. Methods include genetically or otherwise modifying plants and for treating or preventing disease in plant cells comprising a cell wall. Transgenic plants include a nucleic acid molecule of interest produced by regeneration of whole plants from plant cells transformed with linear nucleic acid molecules.

  • Patent number: 8609420
    Abstract: Provided are methods for introducing a molecule of interest into a plant cell having a cell wall by using a QD-peptide conjugate having a quantum dot (QD) with one or more cell penetrating peptides (CPPs). Methods are provided for genetically or otherwise modifying plants and for treating or preventing disease in plant cells comprising a cell wall.

  • 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.

  • Patent number: 8575424
    Abstract: Methods for introducing a functionalized linear nucleic acid cassette molecule of interest into a plant cell comprising a cell wall include use of nanoparticles. In some embodiments, the cell comprising a cell wall is a cultured plant cell. Methods include genetically or otherwise modifying plant cells and for treating or preventing disease in any plant, especially crop plants. Transgenic plants include a nucleic acid molecule of interest produced by regeneration of whole plants from plant cells transformed with functionalized linear nucleic acid cassette molecules.

  • Patent number: 8206983
    Abstract: The subject invention provides simple and consistent methods to break suspension cell aggregates to single cells with intact primary cell walls. The subject invention relates in part to cell separation of suspension cell aggregates cultured in medium containing pectin-degrading enzymes or tubulin de-polymerizing compounds including colchicine. The subject invention also relates to novel uses of compounds for such purposes. Another aspect of the subject invention relates to transformation of the subject, isolated cells. Such processes simplify and integrate single-cell-based transformation and selection processes into transgenic and transplastomic event-generation work processes. The subject invention also removes technical constraints and produces marker-free and uniformly expressing transgenic lines in a high throughput fashion to support various needs of animal health, biopharma, and trait and crop protection platforms.
