    Determination of untargeted compounds in e-liquids using high-performance liquid chromatography-time of flight-mass spectrometry (LC-ToF-MS)

    CHALCRAFT K.; JOZA P.; BIERNACKA P.; LI D.
    Labstat International Inc., Kitchener, ON, Canada
    Techniques like headspace-solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GCMS) can identify a wide range of volatile and semi-volatile compounds in e-liquids associated with flavor active compounds of different classes. The...

    Development of user-friendly markers for disease resistance to black root rot through genotyping by sequencing

    QIN Q.; LI Y.; MARTINEZ N.; MILLER R.; DING N.; WU X.; LI D.; YANG S.
    University of Kentucky, Lexington, KY, USA
    Caused by the fungus Thielaviopsis basicola, black root rot (BRR) can be a very severe problem if susceptible tobacco varieties are planted in fields that have not been rotated well. This disease, characterized by black lesions on the roots and...

    Genetic mapping of black shank resistance in burley tobacco

    BAO Y.; SUI X.; WU X.; MARTINEZ N.; LI D.; MILLER R.; YANG S.
    Department of Plant and Soil Sciences, University of Kentucky, Lexington, KY 40546, USA
    Black shank, caused by the soil-borne pathogen Phytophthora nicotianae, is one of the most devastating diseases in many tobacco-growing areas worldwide. Host resistance is considered as an efficient, economic and environmental friendly means of...

    Genetic mapping of blue mold resistance in burley tobacco

    WU X.; BAO Y.; SUI X.; MARTINEZ N.; LI D.; MILLER R.; YANG S.
    Department of Plant and Soil Sciences, University of Kentucky, Lexington, KY 40546, USA
    Blue mold, caused by the downy mildew pathogen Peronospora tabacina, is one of the most important foliar diseases of cultivated tobacco worldwide. Given the economic cost and possible negative environmental effects of long-term fungicide application,...

    Determination of pyrazine flavourants in electronic cigarette cartridges and liquids by headspace solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GCMS)

    JOZA P.; LI D.; MASTERS A.; RICKERT W.
    Labstat International ULC, Kitchener, ON, Canada
    The purpose of this study was to implement HS-SPME-GCMS, used for profiling volatile and semi-volatile compounds in tobacco products, to electronic cigarettes and e-liquids for the determination of four targeted analytes; 2,3,5-Trimethylpyrazine...
