Viruses are common agents of plant infectious diseases. During last decades, worldwide
agriculture production has been compromised by a series of epidemics caused by new …

High throughput sequencing (HTS) has revolutionised virus detection and discovery,
allowing for the untargeted characterisation of whole viromes. Viral metagenomics studies …

Plant viruses are widespread in nature, where they operate in intimate association with their
hosts and often with vectors. Most research on plant viruses to the present has focused on …

The effect of biodiversity on the ability of parasites to infect their host and cause disease (ie
disease risk) is a major question in pathology, which is central to understand the emergence …

Human alteration of natural habitats may change the processes governing species
interactions in wild communities. Wild populations are increasingly impacted by agricultural …

Dust and sandstorm events inject substantial quantities of foreign microorganisms into
global ecosystems, with the ability to impact distant environments. The majority of these …

Viral diversity has been discovered across scales from host individuals to populations.
However, the drivers of viral community assembly are still largely unknown. Within-host viral …

Disease dilution (reduced disease prevalence with increasing biodiversity) has been
described for many different pathogens. Although the mechanisms causing this …

Wild plant populations may harbour a myriad of unknown viruses. As the majority of
research efforts have targeted economically important plant species, the diversity and …

Research on plant viruses in natural ecosystems has been increasing rapidly over the past
decade. This paper reviews recent research on the barley and cereal yellow dwarf viruses …
