    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 ...
