Patents by Inventor Andy A. Vaewhongs

Andy A. Vaewhongs has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Cytoplasmic gene inhibition or gene expression in transfected plants by tobraviral vector
    Publication number: 20040088757
    Abstract: This invention is directed to a monopartite RNA viral vector comprising modified tobravirus RNA-1 comprising an inserted foreign RNA sequence. This invention is also directed to a bipartite RNA viral vector derived from a tobravirus, wherein the vector comprises one or more foreign RNA sequences. The invention is directed to a method of silencing one or more endogenous plant host genes and a method of simultaneously silencing a plant host gene and expressing a foreign gene in a plant host. Such methods comprise infecting a plant host with a bipartite vector comprising modified tobravirus RNA-1 and RNA-2. The invention is further directed to a method of compiling a plant functional gene profile, a method of changing the phenotype or biochemistry of a plant host, and a method of determining the presence of a trait in a plant host, using a monopartite or bipartite viral vector derived from a tobravirus.
