  • Publication number: 20110023178
    Abstract: The present invention provides a method for producing plants with a desired phenotypic trait which comprises subjecting plants to mutagenesis, screening chimeric progeny for plants having the desired phenotypic trait, and propagating the survivors. In an embodiment, the phenotypic trait comprises an altered amino acid content. Preferably, the technique is used to generate Nicotiana tobacum plant lines having an increase in at least one amino acid. In a preferred embodiment, the invention provides improved Nicotiana tobacum plant lines producing at least 1.35 nmole of threonine per milligram of dry plant weight. These plants are useful for improving the flavor and aroma of the tobacco.

  • Publication number: 20100294289
    Abstract: A filtered cigarette possesses a smokable rod and a filter element. The smokable rod is secured to the filter element using tipping material. The cigarette possesses more than one layer of tipping material. An outer layer of tipping material can overlie at least a portion of an underlying inner layer of tipping material, and during use by the smoker, the outer layer can be removed from the cigarette. Thus, it is possible for a cigarette manufacturer to provide a cigarette that can be used as such by the smoker, or that can be adapted by the smoker to provide a different sensory experience (e.g., the visual, organoleptic, trigeminal, aromatic, and tactile characteristics of the cigarette can be altered by removal of the outer tipping material). Alternatively, the use of the outer layer of tipping material can be used to improve the physical integrity of the cigarette.
