In Tunisia, potato virus Y (PVY) currently presents a significant threat to potato production, reducing tuber yield and quality. Three hundred and eighty-five potato samples (six different cultivars) collected in autumn 2007 from nine regions in Tunisia were tested for PVY infection by DAS-ELISA. The virus was detected in all regions surveyed, with an average incidence of 80.26%. Subsequently, ...

Most routine testing for plant viruses is currently carried out using monoclonal and polyclonal antibodies. Traditional methods of antibody production however can be time consuming and require the use of expensive cell culture facilities. Recombinant antibody technology however is starting to make an impact in this area, enabling the selection of antibody fragments in a few weeks compared with ...

Goal. Molecular identification of carriers the potato virus Y (PVY) resistance genes Rychc and Ryadg among lines Polissia Research Station Institute Potato Growing National Academy Agrarian Sciences Ukraine.
 Methods. Seventy produced by were studied. We used molecular markers indicating presence specific Ry in genome lines. Those are responsible for plant’s response to pathogen extreme (E...
