    Agronomic performance of Polalta-derived breeding lines resistant to tomato spotted wilt virus

    KORBECKA-GLINKA G.(1); TROJAK-GOLUCH A.(1); BAKAHER N.(2); GOEPFERT S.(2)
    (1) Institute of Soil Science and Plant Cultivation (IUNG) - State Research Institute, Puławy, Poland - gkorbecka@iung.pulawy.pl; (2) Philip Morris Products S.A., PMI R&D, Neuchâtel, Switzerland
    Tomato spotted wilt virus (TSWV) is one of the most important pathogens threatening tobacco cultivation. The dark-cured cultivar Polalta is TSWV-resistant, but it cannot be easily incorporated into breeding programs, because its hybridization with...

    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

    DEWEY R.E.(1); BOVET L.(2); GOEPFERT S.(2); CAMPANONI P.(2); LEWIS R.S.(1)
    (1) North Carolina State University, Dept. of Crop and Soil Sciences, Raleigh, NC, U.S.A.; (2) PMI R&D, Philip Morris Products S.A., Neuchatel, Switzerland
    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...

    Testing performance of tobacco varieties in water stress conditions

    CAMPANONI P.(1); LAPARRA H.(1); OZELLEY P.(1); DELLA CIANA P.(3); BISCARINI E.(3); MAURIZI L.(2); NARDONI N.(2); TRIPPELLA C.(2); GOEPFERT S.(1)

    Increasing climate instability could lead to local agricultural constraints, presenting a risk for volumes and quality of tobacco supply. Selecting and breeding tobacco varieties for the ability to perform in unfavourable water conditions becomes a...

    Downregulation of a putative nitrate transporter gene substantially reduces the accumulation of TSNAs in air-cured tobaccos

    GOEPFERT S.(1); BOVET L.(1); LU J.(2); CAMPANONI P.(1); LEWIS R.S.(2); DEWEY R.E.(2)
    (1) Philip Morris Products S.A. (part of Philip Morris International group of companies), PMI R&D, Neuchâtel, Switzerland; (2) North Carolina State University, Department of Crop Science, Raleigh, NC, U.S.A.
    Air-cured Burley tobacco leaves typically exhibit high levels of nicotine-derived nitrosamine ketone (NNK) and N'-nitrosonornicotine (NNN). It has been previously demonstrated that leaf nitrate accumulation in air-cured tobaccos serves as the source...

    The influence of Nicotiana alata-derived introgression on plant malformations of tobacco breeding lines resistant to tomato spotted wilt virus

    KORBECKA-GLINKA G.(1); TROJAK-GOLUCH A.(1); DOROSZEWSKA T.(1); GOEPFERT S.(2)
    (1) Institute of Soil Science and Plant Cultivation - State Research Institute, Pulawy, Poland; (2) Philip Morris Products S.A. (part of Philip Morris International group of companies), PMI R&D, Neuchâtel, Switzerland
    Tomato spotted wilt virus (TSWV) is one of the most destructive viruses for tobacco cultivation. Cultivar “Polalta” carries a resistance gene introgressed from a wild species, Nicotiana alata, but the use of this cultivar in breeding is hampered by...

    Genetic approaches and resources for enabling compliance to proposed NNN standards

    DEWEY R.E.(1); LEWIS R.S.(1); LU Jianli(1); BOVET L.(2); GOEPFERT S.(2); CAMPANONI P.(2)
    (1) North Carolina State University, Raleigh, NC, USA; (2) Philip Morris International, Neuchatel, Switzerland
    Tobacco-specific nitrosamines (TSNAs) are formed through the nitrosation of tobacco alkaloids. Over the past decade, we have demonstrated how altering the genetics of the tobacco plant can result in dramatic reductions in TSNA formation. This has...
