摘要： 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 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 chemical transformation releasing at least a portion of a glycosidically bound compound in the flower of the Nicotiana species. 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.

摘要： The present disclosure provides compositions and methods for editing a target site of a plant genome by delivery of functional editing components using modified tobacco mosaic virus (mTMV). The methods disclosed herein can be used to deliver a gene editing system, such as a DNA endonuclease, to a tobacco plant cell for modification of a target site of the plant genome. Further, the methods and compositions disclosed herein provide for production of a RNA molecule encoding a meganuclease in vitro prior to delivery of the RNA to a plant cell. After introduction of the nucleic acid molecule encoding a functional editing component and subsequent expression of the functional editing components, the plant can be cultured and allowed to produce seeds having an edit at a genomic target site. The seeds can then undergo embryo rescue and be cultured to produce a modified plant without heterologous genetic material.

摘要： A tobacco composition for use in a smoking article or a smokeless tobacco composition is provided, the composition including a component derived from a seed of the Nicotiana species. The component can be a seed of the Nicotiana species or a portion thereof in particulate form or in the form of seed isolate derived from a seed of the Nicotiana species. In certain embodiments, the seed isolate is in the form of a chemically transformed seed isolate, the chemical transformation being selected from hydrogenation, acid/base reaction, hydrolysis, thermal treatment, and enzymatic treatment. The invention also provides smoking articles and smokeless tobacco compositions that include the seed components described herein, and methods for preparing a component derived from a seed of the Nicotiana species for addition to a tobacco composition.
