  • Publication number: 20160330952
    Abstract: The invention provides methods for the encapsulation of volatile organic compounds by formation of stable emulsions of the volatile organic compound that are mixed with encapsulating polymer solutions and then formed into ultrafine fibers. The ultrafine fibers containing the encapsulated volatile organic compounds can be formed into a variety of formats for use to preserve perishable products.

  • Patent number: 7326826
    Abstract: The invention features a method of selecting for a grape somatic embryo or grape plant having resistance to a plant pathogen using a liquid culture medium. The method including the steps of (a) culturing a grape embryonic culture in a first liquid culture medium to grow a cellular suspension culture, the first liquid culture medium including a plant growth regulator and a filtrate from a plant pathogen culture; (b) recovering an embryogenic cell or embryogenic cell mass from the cellular suspension culture; and (c) culturing the embryogenic cell or embryogenic cell mass in a second liquid culture and in a third culture media to select a grape somatic embryo or a grape plant having resistance to a plant pathogen.

  • Publication number: 20060035377
    Abstract: The invention features a method of producing a grape somatic embryo having resistance to a plant pathogen, the method including the steps of (a) culturing a grape somatic embryo in a first liquid culture medium that includes a plant growth regulator and a phytotoxin from a plant pathogen; (b) exchanging the first liquid culture medium for a second liquid culture medium not including the phytotoxin; (c) recovering a living grape cell or grape cell cluster from the second liquid culture, the living cell or cell cluster being resistant to the pathogen; and (d) culturing the grape cell or grape cell cluster in a third culture medium to produce a grape somatic embryo.
