Interactions between potato virus Y and potato spindle tuber viroid

In Helsinki, Finland, studies were carried out to investigate the effects on the accumulation of potato virus Y (PVY) though co-infections of Solanum brevidens by other viruses and viroids. It was found that a co-infection with potato spindle tuber viroid (EPPO A2 organism) enhanced the accumulation of PVY 1000-fold.
