First report of Tomato torrado virus in Poland

In Poland, unusual disease symptoms were observed on tomatoes (Lycopersicon esculentum cv. Grace) in the Wielkopolska region in 2003 and 2004. Affected plants showed severe stunting, leaf deformation and necrosis. The occurrence of the disease also appeared to be associated with the presence of Trialeurodes vaporariorum. Electron microscopy revealed the presence of spherical virus particles (25-28 nm diameter). Laboratory studies were conducted to identify the virus present (transmission studies, ISEM, RT-PCR, comparison of sequences). The similarity of symptoms on tomato plants, the morphology of virus particles, genome composition and nucleotide sequences strongly suggested that the virus found in Poland is identical to Tomato torrado virus (ToTV) which has recently been identified in Spain (see EPPO RS 2007/128). This is the first report of ToTV in Poland.
