  • Patent number: 9137958
    Abstract: Disclosed herein are genetically modified tobacco plants, and tobacco products derived from such plants, comprising an altered uptake and/or altered levels of at least one environmental contaminant or other non-natural chemical as compared to an unmodified parent tobacco plant from which the modified plant is derived. The alteration in uptake and/or levels may be a reduction, or alternatively an increase, in the uptake and/or levels of the environmental contaminant or other non-natural chemical. These methods and plants are useful for improving tobacco products or in generating tobacco lines that may have environmentally useful properties.

  • Patent number: 8955523
    Abstract: The invention provides a tobacco composition for use in a smoking article or a smokeless tobacco composition that includes an additive derived from a flower of the Nicotiana species. The additive can be a flower of the Nicotiana species or a portion thereof in particulate form or in the form of flower isolate derived from a flower of the Nicotiana species. In certain embodiments, the flower isolate is in the form of an extract from a flower of the Nicotiana species or in the form of a chemically transformed flower isolate, the chemical transformation being selected from acid/base reaction, hydrolysis, thermal treatment, and enzymatic treatment. The invention also provides smoking articles and smokeless tobacco compositions that include the flower additives described herein, and methods for preparing an additive derived from a flower of the Nicotiana species for addition to a tobacco composition.

  • Publication number: 20140224269
    Abstract: The present invention discloses genetically modified tobacco plants, and tobacco products derived from such plants, comprising a decrease in at least one amino acid such that upon heating and/or burning, the tobacco plant or a portion thereof generates reduced levels of a compound derived from the at least one amino acid as compared to an unmodified parent tobacco plant or a portion thereof In an embodiment, the tobacco generates reduced levels of acrylamide and/or acrylonitrile upon heating and/or burning of the tobacco as compared to an unmodified parent tobacco line. These plants are useful for improving tobacco products.
