Abstract: The present invention generally relates to the reduction of the harmful effects of orally or transdermally delivered nicotine in conventional tobacco-use cessation programs. More specifically, embodiments concern methods of reducing the harmful effects of nicotine intake, associated with conventional tobacco-use cessation programs, by providing tobacco products, which contain a reduced amount of nicotine and/or tobacco specific nitrosamines (TSNAs).

Abstract: DNA encoding a plant quinolate phosphoribosyl transferase (QPRTase) enzyme, and constructs comprising such DNA are provided. Methods of altering quinolate phosphoribosyl transferase expression are provided.

Abstract: The present invention generally relates to tobacco and tobacco products having a reduced amount of nicotine and/or tobacco specific nitrosamines (TSNA). More specifically, several ways to make tobacco plants that have reduced nicotine and TSNA levels have been discovered. Embodiments include tobacco harvested from said tobacco plants, cured tobacco from said tobacco plants, tobacco products made with said cured tobacco and methods of making these compositions.

Abstract: The present application describes isolated nucleic acids that contain a Nic gene product responsive element, and the use thereof in methods of producing transgenic tobacco plants having reduced levels of nicotine and/or TSNA therein, as well as other plants or host cells that contain altered levels of a protein of interest therein due to inclusion of a cis-acting decoy element therein.

Abstract: Aspects of the present invention concern tobacco having reduced nicotine and nitrosamines, which is used to manufacture consumer tobacco products, and methods to produce such tobacco. More specifically, embodiments include methods to reduce nicotine and nitrosamines in tobacco crops by applying auxin, auxin analogs, and jasmonate antagonists during the cultivation of such tobacco crops. Tobacco generated using said methods and consumer tobacco products obtained therefrom are also embodiments.

Abstract: Nematode-resistant transgenic plants are disclosed. The plants comprise plant cells containing a DNA construct comprising a transcription cassette, which construct comprises, in the 5' to 3' direction, a promoter operable in the plant cells, and a DNA comprising at least a portion of a DNA sequence encoding a nematode-inducible transmembrane pore protein in either the sense or antisense orientation. Intermediates for producing the same along with methods of making and using the same are also disclosed. In an alternate embodiment of the invention, the sense or antisense DNA is replaced with a DNA encoding an enzymatic RNA molecule directed against the mRNA transcript of a DNA sequence encoding a nematode-inducible transmembrane pore protein.
