The ecology of plant viruses began to be explored at the end of the 19th century. Since then,
major advances have revealed mechanisms of virus-host-vector interactions in various …

Viruses are estimated to be responsible for approximately 50% of the emerging plant
diseases, which are difficult to control, and in some cases, there is no cure. It is essential to …

Phytoviruses are highly destructive plant pathogens, causing significant agricultural losses
due to their genomic diversity, rapid, and dynamic evolution, and the general inadequacy of …

Background In agroecosystems, viruses are well known to influence crop health and some
cause phytosanitary and economic problems, but their diversity in non-crop plants and role …

Virus evolution is the change in the genetic structure of a viral population over time and
results in the emergence of new viral variants, strains, and species with novel biological …

The discovery of the first non-cellular infectious agent, later determined to be tobacco
mosaic virus, paved the way for the field of virology. In the ensuing decades, research …

Crop yield loss caused by phytopathogens has a massive impact on global economy. For
over a century, agrochemicals have been used for plant disease management; however, the …

Pollen is a unique vehicle for viral spread. Pollen-associated viruses hitchhike on or within
pollen grains and are transported to other plants by pollinators. They are deposited on …

Viral metagenomics has expanded our knowledge of the ecology of uncultured viruses,
within both environmental (eg, terrestrial and aquatic) and host-associated (eg, plants and …

Background Research into public risk perceptions associated with emerging risks in
agriculture and supply chains has focused on technological risks, zoonotic diseases, and …
