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.
