A tospovirus was isolated by mechanical sap transmission from potato plants showing leaf and stem necrosis symptoms and identified as tomato yellow fruit ring virus (tyfrv) based on biological, serological and molecular studies. A thesis submitted in partial fulfillment of the requirements for the degree suitability of five different greenhouse-grown vegetable crops: tospoviruses are. Goals / objectives determine the molecular basis of virus-host interactions using thrips-trasnsmitted tospoviruses infecting vegetables as a model system characterize the nature of interaction between late blight resistance and virus susceptibility in potato.

Massimo turina, marina ciuffo, in advances in virus research, 2012 abstract tospoviruses are among the most serious threats to vegetable crops in the mediterranean basin. An unusual disease of watermelon (citrullus lanatus) in india, with symptoms of leaf crinkling, mottling, yellowing, necrotic streaks on vines, shortened internodes, upright branches and necrosis and dieback of the buds was caused by the watermelon strain of tomato spotted wilt tospovirus (tswv-w.

Current status of tospoviruses infecting vegetables in asiathrips-transmitted tospoviruses (genus tospovirus, family bunyaviridae) are among the most economically important plant pathogens in the world because of their ability to cause severe crop losses (mumford et al 1996 pappu et al 2009. Tospoviruses are emerging viruses not only in the sense of their increasing economic importance as pathogens on a worldwide basis, but also in that our understanding of the complexity of this new viral taxon only began to emerge during the last decade. A catalogue is presented of pepper (capsicum spp) varieties and lines exhibiting resistance to plant viruses, to improve the use of these genotypes by plant breeders. Abstract studies were carried out on a population ofthrips tabaci lindeman (thysanoptera: thripi-dae) from liguria to assess its sex-ratio and its ability to transmit four tospoviruses: tomato spotted wilt (tswv), impatiens necrotic spot, tomato chlorotic spot and groundnut ringspot. An isolate of cucumber mosaic virus (cmv) retrieved from tomato in india was characterized based on its transmission by sap inoculations, western blot immuno-assay and sequence analysis of rna3 and 2b genome.

Pdf | this study was carried out to determine the presence of tomato spotted wilt virus (tswv) in vegetable growing areas, during growing seasons of 2006 and 2007 in the west mediterranean region. Tospoviruses have a very wide host range and can be transmitted by ten different thrips species using disease-free and disease-resistant tomato transplants is the best way to prevent the spread of tospoviruses.
