    Dynamics of molecular leaf senescence processes occurring during curing of Virginia tobacco cultivar K326

    CHEVAL C.; BATTEY J.; SIERRO N.; DULIZE R.; BORNAND D.; SIMICEVIC J.; TITZ B.; GUY P.A.; LASZLO C.; HAIDUC A.; DOSSIN E.; BOVET L.; IVANOV N.; GOEPFERT S.

    Consequences of molecular genetic alteration of leaf nitrate levels on TSNAs, alkaloids, flowering time, and biomass in Burley tobaccos

    We have previously demonstrated that tobacco-specific nitrosamine (TSNA) levels in Burley tobaccos can be substantially lowered using two distinct molecular genetic techniques designed to impede the plant’s ability to store high levels of free...

    Metabolic and transcriptomic shifts during tobacco leaf post-harvest senescence

    BOVET L.; HILFIKER A.; BATTEY J.; SIERRO N.; GOEPFERT S.
    PMI R&D, Philip Morris Products S.A., Neuchâtel, Switzerland
    Tobacco is harvested after plant flowering, when the leaf senescence is more or less visible depending on cultivars. Before the drying phase, current practices allow the senescence to proceed until the detached leaf becomes yellow. This yellowing...

    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...

    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...
