New necrotic isolates of Pepino mosaic virus (PepMV) were found in 2007 infecting greenhouse tomato plants in Poland. The isolates differ from previously identified PepMV isolates in host range and symptomatology. They induce severe necrosis on tomato plants ( Solanum lycopersicum ) and local necrotic lesions on Datura inoxia . Phylogenetic analysis, based on three distinct regions, triple gene block 1, the coat protein gene and a part of polymerase gene, revealed that the new necrotic isolates share high nucleotide sequence identity with isolates of the Ch2 genotype. This is the first report describing a necrotic type of PepMV of the Ch2 genotype.
