Potato virus Y: biodiversity, pathogenicity, epidemiology and management

Potato virus Y (PVY) infects a wide host range mainly within the Solanaceae and is distributed worldwide. PVY is transmitted by more than 40 aphid species in a non persistent manner. Isolates of the PVY species are highly variable at biological, serological and molecular levels. Epidemiological studies have highlighted the emergence of distinct potato PVY variants able to induce necroses on potato tubers. Due to the lack of efficient resistance to PVY isolates inducing necrotic symptoms in cultivated varieties and the plant-to-plant transmission of isolates through the daughter tubers, PVY has become the most economically important virus for the potato industry. The review offers an overview of several decades of research on PVY but also focuses on the latest data obtained by expert on PVY worldwide on the biological characteristics of PVY, interactions between aphids-hosts, its evolution and management. Identified knowledge gaps to understand further PVY biology will be discussed.

A timely overview of several decades of research on PVY, one of the most important plant viruses that will appeal to a broad academic audience (universities, public and private funded institutions) and the wide agri-biotech industry (growers, agronomist, breeders, policy) Presents the latest data (published and yet unpublished) obtained by collaborating scientists (all known as expert on PVY pathosystem) from different countries worldwide (i.e. members of the PVY-Wide organization) Experts in the field of virology have gathered to present an exhaustive overview of disease symptoms caused by PVY that will be presented at the highest iconographic standard (high definition colour pictures) providing a reference for the laboratory and field scientists and academics Presents the roadmap of future PVY research integrating current widely used approaches and novel/emerging technologies that will shape the future of epidemiology, pathology and diagnosis research
