  • 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.

  • Publication number: 20110318348
    Abstract: The subject invention provides, for example, a novel approach to specifically induce intranasal and/or oral mucosal as well as humoral antibody response by administrating a mucosal delivery pentabody complex (MDPC). The MDPC is a complex formed by mixing a target antigen and a mucosal delivery pentabody (MDP) that has a strong affinity to the target antigen. The MDP is a fusion protein of a single domain antibody (sdAb; which binds to the target antigen specifically) to a pentamerization domain (which can include the B-subunit of an AB5 toxin family, including the B subunit of cholera toxin (CT) or heat-labile toxin (LT)). The pentamerization domain can self-assemble into a pentamer, through which a pentameric single domain antibody, or a pentabody, is formed.

  • Publication number: 20110191899
    Abstract: A method for producing a transgenic plant includes providing a nucleic acid molecule comprising at least two regions of nucleic acid sequence that lack sequence homology with genomic DNA of the plant cell, and at least two zinc finger nuclease recognition sites, wherein the at least two regions of nucleic acid sequence that lack sequence homology with genomic DNA of the plant cell flank the at least two zinc finger nuclease recognition sites. A plant cell or tissue having the nucleic acid molecule stably integrated into the genome of the plant cell is transformed. A plant is regenerated from the plant cell. Transgenic plants are produced by the method. Seeds are produced by the transgenic plants.

  • Patent number: 7982006
    Abstract: This invention pertains in part to the development of a vaccine for poultry against necrotic enteritis (NE). The vaccine utilizes a protective antigen that is a mutated, full-length, non-toxic Clostridium perfringens (Cp) ?-toxin protein (Mcpa). Utility of this vaccine was demonstrated by reduction of lesion severity in NE challenge trails, for example. Also disclosed herein are novel approaches for producing this vaccine in significant quantities. One exemplified approach involves producing NE vaccine (mutated alpha toxin) in bacterial expression systems, preferably utilizing the Pseudomonas fluorescens system, for commercial use in controlling NE in the poultry industry. The subject vaccines can be administered preferably to chickens in several different ways. A novel, Type VI alpha toxin from chicken isolates of Cp is also disclosed.

  • Patent number: 7371935
    Abstract: Genetic constructs, transformation vectors and methods are taught for production of transgenic plants which can be selectively removed from a growing site by application of a chemical agent or physiological stress. The invention links a target gene for the trait of commercial interest to a conditionally lethal gene, which can be selectively expressed to cause plant death. By use of the genetic constructs, transformation vectors and methods of the present invention, invasion of environments and contamination of commercial non-engineered productions by transgenic plants can be avoided. Methods are also taught for transformation of Brassica species.
