    A comprehensive survey of the N. tabacum transcriptome (The European Sequencing of Tobacco Project, ESTobacco)

    DORLHAC DE BORNE F.; COATES S.; ROSS J.; VERRIER J.L.; JONES L.; JULIO E.; DELON R.
    Altadis - Institut du Tabac, Bergerac, France
    Tobacco genome research is expected in the next few years to improve our knowledge about the interactions between genes involved in the formation of undesirable compounds in cigarette smoke. A close link exists between gene expression in the tobacco plant ...

    Overview of tobacco variety evolution in France 1989-2005 and impact to the raw matter characteristics

    VERRIER J.L.; MANDON A.; AMAN J.L.; JUBELY J.; BARDON J.C.; LUCIANI A.; DELON R.
    Altadis - Institut du Tabac, Bergerac, France
    From 1989 to 2005, the French tobacco crop evolved dramatically. A near complete disappearance of dark air-cured types was accompanied by a substantial increase in flue-cured and Burley. Varieties from foreign origin were lacking appropriate adaptation ...

    Evaluation of resistance to the tobacco cyst nematode complex (Globodera tabacum) in the genus Nicotiana and the species Nicotiana tabacum L

    VERRIER J.L.; CAILLETEAU B.; DELON R.; MUGNIÉRY D.
    Altadis - Institut du Tabac, Bergerac, France
    Cyst nematodes from the complex species Globodera tabacum (GT) affect tobacco in Europe and U.S.A. In France, damages have been recorded in the Garonne valley and adjacent areas (south west), since at least 1985. Several Nicotiana species and N. tabacum ...

    Tobacco as a model plant to study the infectious structures of pathogen bacteria

    RACAPE J.; PARLANGE F.; BELBAHRI L.; NICOLE M.; VERRIER J.L.; DELON R.; KELLER H.
    INRA, Unité Interactions Plantes-Microorganismes et Santé Végétale, Antibes, France
    Bacterial pathogens use common strategies to infect their host cells in plants or animals. Among these strategies, the type III secretion system allows not only the secretion, but also the injection of pathogenicity factors into eucaryotic host cells. To ...

    Proposed growth stages and identification keys for tobacco (Nicotiana tabacum L.)

    PAPENFUS H.D.; PRAT M.; DELON R.
    Standard Commercial Tobacco Co. UK - JT Intl, Trier, Germany - Altadis, Institut du Tabac, Bergerac, France
    One of the requirements for implementing Good Agricultural Practice is a clear, universally adaptable means of accurately identifying the different growth stages of crops. In the case of tobacco, terms such as 'after lay-by', 'mid-growth& ...

    Seed quality management as a component of tobacco identity preservation

    VERRIER J.L.; CAILLETEAU B.; BARDON J.C.; JUBELY J.; DELON R.
    Altadis - Institut du Tabac, Bergerac, France
    Tobacco seed quality involves a series of attributes, the number of which has increased in recent years. Aside identity to the variety, genetic purity, absence of pathogens, seed viability and vigor, recent evolutions have highlighted the necessity of ...

    Comparative study of leaf surface texture and ability to expand of cured tobacco

    ROHR R.; EBERHARD A.; DELON R.
    Université Claude Bernard Lyon 1, Villeurbanne, France
    Tobacco leaf texture, appreciated by the difference of surface roughness of cured leaves, is studied with light microscopy and scanning electron microscopy (SEM). The leaf texture is obviously determined by the presence or absence of conical cellular ...
