    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 phase is ...
