    Characterisation of the Rk1 resistance to Meloidogyne in tobacco by RNA-Seq analysis

    JULIO E.; COTUCHEAU J.; DECORPS C.; LAURENT T.; DORLHAC de BORNE F.
    SEITA, Imperial Tobacco Group, Bergerac, France
    The root-knot nematode (Meloidogyne spp.) is a major pest causing severe damages in many tobacco growing areas such as Europe, Brazil or Africa. The use of nematicides to fumigate soils is not compatible with efforts to reduce agrochemical residues...

    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...
