RNA silencing is directly involved in antiviral defense in a wide variety of eukaryotic organisms, including plants, fungi, invertebrates, and presumably vertebrate animals. The study of RNA silencing-mediated antiviral defences in vertebrates is hampered by the overlap with other antiviral mechanisms; thus, heterologous systems are often used to study the(More)
The grapevine (Vitis vinifera L.) cultivars ‘Agiorgitiko’ and ‘Malagouzia’, naturally infected with Grapevine rupestris stem pitting-associated virus (GRSPaV), were subjected to in vitro chemotherapy using the antiviral inosine 5′-monophosphate dehydrogenase inhibitors tiazofurin (TR), ribavirin (RBV) and mycophenolic acid (MPA). The chemotherapy lasted 80(More)
Four poleroviral isolates from Greece, two from lettuce, one from spinach and one from watermelon showing yellowing symptoms, were molecularly characterized by analyzing the sequence of a large part of the genome spanning from the 3′-terminal part of the RdRp to the end of the CP gene. The sequences were analyzed for their similarity and phylogenetic(More)
A novel strategy employing the rhabdovirus untranslated conserved intergenic regions was developed and applied successfully for the determination of the complete nucleotide sequence of Eggplant mottled dwarf virus (EMDV). The EMDV genome contains seven open reading frames with the same organization as Potato yellow dwarf virus (PYDV), the type species of(More)
The genetic diversity of eggplant mottled dwarf virus (EMDV), a member of the family Rhabdoviridae, was studied using isolates collected from different herbaceous and woody plant species and remote geographic areas. Sequences corresponding to the N, X, P, Y, M and G ORFs as well as the untranslated regions (UTRs) between ORFs were determined from all(More)
