    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 ...

    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 ...

    Chemical change and cigarette smoke mutagenicity increase associated with CMV-DTL and PVY-N infection in burley tobacco

    VERRIER J.L.; MARCHAND V.; CAILLETEAU B.; DELON R.
    Altadis - Institut du Tabac, Bergerac, France
    It had previously been reported that challenging in field Burley tobacco varieties with CMV-DTL or PVY-N resulted in increased contents of total nitrogen and nitrate in cured leaves. In order to assess a possible impact of virus infection on smoke ...

    The tobacco breeding program of Institut du Tabac (SEITA, ALTADIS) : methods, results and future prospects

    VERRIER J.L.; ANO G.; TANCOGNE J.; VIDAL B.; DELON R.
    Altadis - Institut du Tabac, Bergerac, France
    Tobacco breeding at Tobacco Institute of Bergerac started with TMV resistance, then increased with the blue-mold epidemic of years 60, which necessitated creation and release of new, blue-mold resistant varieties. In order to diversify the French ...

    Leaf quality and yield of Burley and dark air cured tobacco varieties when inoculated with potato virus Y necrotic strain (PVY<sup>N</sup>) or with cucumber mosaic virus (CMV-DTL) in field conditions

    VERRIER J.L.; CAILLETEAU B.; DELON R.; TEPFER M.
    SEITA, Institut du Tabac, Bergerac, France; INRA, Laboratoire de biologie cellulaire, Versailles, France
    The results of 1997 and 1998 field trial with air cured tobacco, comparing non-inoculated controls with mechanically inoculated plots, under conditions of low natural incidence of non persistent aphid-transmitted viruses, lead to the following conclusions ...

    Assessment of the efficacy of CGA 245704 associated or not with CGA 329351 (metalaxyl-M) for the control of blue mold (P. tabacina): results of four years of experimentation

    DELON R.; CAILLETEAU B.; VERRIER J.L.; SYLVESTRE M.
    SEITA, Institut du Tabac, Bergerac, France
    Since 1993, a stimulator of the plant's natural resistance (CGA 245704) or acibenzolar-S-methyl, belonging to the benzothiadiazole group, has been tested for blue mold (P. tabacina) control both on seedbeds and on the field. An application of CGA ...
