Abstract
A virus isolated from diseased tobacco plants growing in Macedonia, northern Greece, had host range and physico-chemical properties typical of a tobravirus. Although it was serologically unrelated to any of the ten tobravirus isolates tested, it reacted in spot hybridization tests with a probe derived from RNA-1 of tobacco rattle virus (TRV) strain SYM. Therefore, the isolate probably represents a previously undescribed serotype of TRV. Male, female and juvenileTrichodorus similis nematodes recovered from the rhizosphere of the diseased tobacco plants transmitted TRV in each of three laboratory experiments. In two of these experiments 50% and 54%, respectively, of the nematodes transmitted virus toPetunia hybrida bait plants, whereas only 18% transmitted virus toNicotiana tabacum plants in a third test. Ultrathin sections of the feeding apparatus of individual nematodes, which had transmitted virus, were examined by electron microscopy. Virus particles were observed, retained as a monolayer in the apices of the oesophageal lumen and as a group of particles within a matrix in the open part of the lumen.
