The majority of plant-infecting viruses are transmitted to their host plants by vectors. The
interactions between viruses and vector vary in duration and specificity but some common …

Viruses are highly evolvable biological entities capable of wreaking havoc on our society.
Therefore, a better understanding of virus evolution is important for two main reasons:(i) it …

This review addresses some of the biological complexities presented by aphid-transmitted
viruses of potato, Solanum tuberosum L., and their vectors and discusses the application of …

Viral diseases of potatoes can cause significant yield and quality losses for the commercial
producer but are of particular concern to the seed potato producer. Potato virus Y (PVY) and …

Viruses are frequently a microbial biocontaminant of healthy plants. The occurrence of the
infection can be also due to environmental stress, like urbanisation, air pollution and …

Plants regularly encounter abiotic constraints, and plant response to stress has been a focus
of research for decades. Given increasing global temperatures and elevated atmospheric …

As obligate parasites, plant viruses need to move from infected to healthy plants in order to
survive. This is achieved either by mechanical means or, in the case of most plant viruses …

Summary Harrington et al.(1986) assessed the relative efficiency with which different aphid
species transmitted potato virus Y (PVY), by trapping flying aphids on a net downwind of a …

Studies were performed to investigate factors affecting symptom expression of potato virus Y
infection in three potato cultivars, Russet Norkotah, Shepody, and Red LaSoda. Quantitative …

The potato is propagated vegetatively through seed tubers. Vector aphids are mainly
responsible for spread of common viruses, viz. PVY, PLRV, PVA etc. Besides, the common …
