    Association mapping in a collection of tobacco reference cultivars. Step One: Variability of smoke constituents

    JULIO E.; VERRON T.; CAHOURS X.; DORLHAC DE BORNE F.; COLARD S.
    Imperial Tobacco Group, Bergerac, France
    Recent developments of sequencing technologies and computational methods have given the opportunity to detect natural variation underlying complex traits in crops. In this purpose, association mapping can be used to identify the link between tobacco genes ...

    Foliar applications of WG®CONTANS against Sclerotinia sclerotiorum on tobacco crop

    KANE K.(1); CAILLETEAU B.(2)
    (1) ARVALIS Institut du Végétal, Bergerac, France; (2) Imperial Tobacco Group, Institut du Tabac, Bergerac, France
    In France, the fungus Sclerotinia sclerotiorum affects tobacco late in the cycle, after topping. The problem has been increasing over the last 6-7 years. Rainfall is an important factor for contamination and spread. Symptoms are stem and leaf vein ...

    Characterisation of PVY (Potato Virus Y) resistance in tobacco: potential role of an eIF4E gene identified by high throughput sequencing technologies

    JULIO E.; COTUCHEAU J.; DECORPS C.; SENTENAC C.; VOLPATTI R.; DORLHAC DE BORNE F.
    Imperial Tobacco Group, SEITA, Institut du Tabac, Domaine de la Tour, Bergerac, France
    Potato virus Y (PVY) is a plant virus belonging to the genus Potyvirus. It is transmitted by aphids, and can cause severe damage in crops. In tobacco, a large deletion conferring resistance to PVY, the “va” gene, is commonly used. This resistance is ...

    Evolutionary pathways of potato virus Y adaption to the resistance gene va in Nicotiana tabacum and impacts for resistance management

    JANZAC B.(1,2); LACROIX C.(1,2*a); TRIBODET M.(1); VERRIER J-L.(2); JACQUOT E.(1*b)
    (1) INRA-Agrocampus Ouest-Université Rennes1, UMR1349 IGEPP (Institute of Genetic, Environment and Plant Protection), Le Rheu, France; (2) Imperial Tobacco Group, SEITA, Institut du Tabac, Bergerac, FranceInteractions), Montpellier, France
    Since the use of tobacco cultivars carrying allelic forms (0, 1 or 2) of the recessive resistance gene va, symptoms associated to PVY infection have often been reported, which suggests viral adaptation to these allelic forms. Biological and serological ...

    TSNA accumulation during post-cure storage of air-cured tobacco: Results of a 2009 experiment

    VERRIER J.L.; WIERNIK A.; STAAF M.; ONILLON M.; LAURENT T.
    Imperial Tobacco Group, Institut du Tabac, Bergerac, France
    In Burley and dark tobacco, tobacco specific nitrosamines (TSNA) are formed during air-curing. A further accumulation may occur post-cure, before threshing and re-drying. The experiment reported here investigates this post-cure accumulation in leaves from ...

    Contribution of near infra-red spectrometry (NIRS) to detect nicotine conversion to nornicotine in Burley tobacco

    VERRIER J.L.; JOURDAIN M.; VERRON T.
    Imperial Tobacco Group, Institut du Tabac, Bergerac, France
    Discarding converter plants is a major goal in the seed production of Burley cultivars, but requires chemical analysis of individual alkaloids. In order to lessen this workload, we explored the possibilities offered by spectrometry. The LabSpec Pro → ...
