    Tobacco germplasm screening for genetic variability, alkaloid accumulation and their relationships

    ROBERT V.J.M.; WERNSMAN E.A.; ROSSI L.; KALENGAMALIRO N.
    Philip Morris Intl, R&D, Neuchâtel, Switzerland.
    Nicotine is the predominant alkaloid in commercially grown tobacco (Nicotiana tabacum L.) and accounts for greater than 90% of the total alkaloid fraction. Nicotine conversion results in formation of nornicotine, which is the amine precursor of N&#039 ...

    Survey on cadmium concentration in flue-cured, burley and oriental tobacco (Nicotiana tabacum) leaves

    LUGON-MOULIN N.; MARTIN F.; KRAUSS M.R.; RAMEY P.B.; ROSSI L.
    Philip Morris Intl, R&D, c/o Philip Morris Products SA, Neuchâtel, Switzerland, Philip Morris Intl Mgt SA, Leaf Agronomy, Lausanne, Switzerland, Philip Morris Intl, R&D, Richmond, VA, USA,
    Cadmium (Cd) is classified as a known human carcinogen (Class 1) by the International Agency for Research on Cancer. It is one of the potential carcinogenic substances in tobacco products. Cadmium accumulation in crop plants such as tobacco (Nicotiana ...

    Reduction of tobacco specific nitrosamines in air-cured tobacco

    LI Qinglin; KRAUSS M.; COLASSACO D.; BOKELMAN G.; GADANI F.; ROSSI L.
    Philip Morris USA, Research Center, Richmond, VA, USA
    Antioxidants, such as phenolics, tocopherols and carotenoids in tobacco leaves, are known to interfere with oxidation processes through chain-breaking reactions or through scavenging of free radicals. The induction or up-regulation of these and other ...

    Preliminary survey of the cadmium content of phosphate fertilizer samples used for tobacco (Nicotiana tabacum L.) production

    LUGON-MOULIN N.; RYAN L.; DONINI P.; ROSSI L.
    Philip Morris Intl, R&D, c/o Philip Morris Products SA, Neuchâtel, Switzerland, Philip Morris Intl Mgt SA, Leaf Agronomy, Lausanne, Switzerland, Philip Morris Intl, R&D, Richmond, VA, USA,
    Cadmium (Cd) is classified as a known human carcinogen (Class 1) by the International Agency for Research on Cancer. It is one of the potential carcinogenic substances in tobacco products. Tobacco (Nicotiana tabacum L.) leaves may accumulate relatively ...

    Quantitative determination of genetic modification markers in tobacco by high-throughput real time PCR

    ROSSI L.; PIJNENBURG H.; BINDLER G.; KOCHER S.; HÄRRI A.; GADANI F.; ZUBER J.
    Philip Morris Products SA, R&D, Neuchâtel, Switzerland.
    Analytical methods based on the polymerase chain reaction (PCR) are widely used to detect, identify and quantify genetically modified organisms (GMOs) in agricultural crops, food and feed. The determination of genetic identity facilitates the ...

    A global tobacco identity preservation program - TIPP

    RYAN L.; GADANI F.; ZUBER J.; ROSSI L.; ARCHIBALD C.; FISHER C.
    Philip Morris International Operations, Lausanne, Switzerland
    The tobacco industry maintains the identity of tobacco types (sun, air or flue-cured) and grades in order to blend these components into the products preferred by our consumers. With TIPP this existing system was further developed to ensure additional ...
  7. CORESTA Meeting, Agronomy/Phytopathology, Suzhou, 1999, AP45

    Potential of molecular marker analysis for assessment of genetic diversity in tobacco varieties

    ROSSI L.; BINDLER G.; PIJNENBURG H.; GADANI F.
    Philip Morris Europe, R&D, Neuchatel, Switzerland.
    The objective of the study was to investigate the genetic diversity of tobacco varieties by developing polymerase chain reaction (PCR)-based procedures that can detect DNA polymorphisms in tobacco. An effective DNA extraction method is required in order ...

    The application of polymerase chain reaction (PCR) technology to the detection, identification and quantification of genetically modified organisms (GMOs): current approaches

    GADANI F.; BINDLER G.; PIJNENBURG H.; ROSSI L.; ZUBER J.
    Philip Morris Europe, R&D, Neuchâtel, Switzerland.
    Analytical methods based on the polymerase chain reaction (PCR) technology are increasingly used for the detection of deoxyribonucleic acid (DNA) sequences associated with genetically modified organisms (GMOs). Prerequisites for GMO detection are a ...
