Potyviruses are the largest group of plant infecting RNA viruses that cause significant losses
in a wide range of crops across the globe. The majority of viruses in the genus Potyvirus are …

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 …

Attacks on plants by both viruses and their vectors is common in nature. Yet the dynamics of
the plant–virus–vector tripartite system, in particular the effects of viral infection on plant …

Aphids severely affect crop production by transmitting many plant viruses. Viruses are
obligate intracellular pathogens that mostly depend on vectors for their transmission and …

Global production of tomato has been hampered by the increased incidences of tomato viral
disease. The high genetic heterogeneity of tomato plant viruses, because of their high …

Insects play an important role in the spread of viruses from infected plants to healthy hosts
through a variety of transmission strategies. Environmental factors continuously influence …

Understanding the emergence and prevalence of viral diseases in crops requires the
systematic epidemiological monitoring of viruses, as well as the analysis of how ecological …

Agricultural crops infected with vector-borne pathogens can suffer severe negative
consequences, but the extent to which phytopathogens affect the fitness of their vector hosts …

Aphids vector many plant viruses in a non-persistent manner ie, virus particles bind loosely
to the insect mouthparts (stylet). This means that acquisition of virus particles from infected …

Viral infections on cucurbit plants cause substantial quality and yield losses on their crops.
The diseased plants can often be infected by multiple viruses, and their epidemiology may …
