title: Role of cucumber mosaic virus and its satellite RNA in the etiology of tomato fruit necrosis in Italy.
abstract: A cucumber mosaic virus (CMV) isolate supporting a natural 390-ribonucleotide satellite was used to reproduce under experimental conditions a disease of processing tomatoes called fruit necrosis. The virus induced incomplete differentiation of the vascular tissue of fruit stalks, which was the likely cause of the disease. On the other hand, the satellite RNA attenuated viral symptoms on tomato leaves reproducing the disease pattern typically observed in the field. The biological properties of this seemingly new variant of cucumoviral satellite RNAs were determined.
