Fourteen Potato virus Y (PVY) isolates representative of PVY(O), PVY(N), PVY(NTN) and PVY(N)W groups were characterised at genomic level. Restriction fragment length polymorphism study (RFLP) of each gene of these isolates and sequencing of the first 2700 nucleotides of two PVY(N)W isolates were performed. A mosaic structure was revealed in PVY(N)W and

Generation of PVY Coat Protein siRNAs in Transgenic Potatoes Resistant to PVY
American Journal of Potato Research, 2012Global climate change has the potential to quickly alter the distribution and profile of crop pests and pathogens. Ready tools for mobilization of resistance into elite crops will be part of an integrated strategy to maintain agricultural productivity. Engineered virus resistance through expression of coat protein is well established. The mechanisms of

The potato virus Y (PVY) complex includes five non-recombinant strains and a growing number of recombinants. Up to now, the bulk of these PVY recombinants were found to be composed of genome segments coming from only two "parental" genomes, PVYO and PVYEu-N, with a small minority including segments from other parents, e.g.

AbstractIsolates of Potato virus Y (PVY), collected in Syria, induced vein necrosis in tobacco but reacted to PVYO monoclonal antibody, and were therefore classified as PVYNW (or PVYN:O). The possible recombinant points within the genome were checked using a previously reported multiplex RT‐PCR.

POTATO VIRUS Y (PVY) ON PEPPER IN SERBIA
Acta Horticulturae, 2002During 1997, samples of plants showing symptoms of a viral disease were collected from thirteen pepper growing areas. On some plants characteristic symptoms of Potato Virus Y (PVY) infection were observed. Pepper samples were tested by applying the direct immunoenzyme test (DAS ELISA).

The mechanisms by which Potato virus Y variants are generated and selected are still unclear. Spontaneous mutations generated by uncorrected replication error and recombination events between viral isolates during co-infection of plant cells are the main likely source of genetic diversity.

Protection against potato virus Y (PVY) in the field in potatoes transformed with the PVY P1 Gene
American Journal of Potato Research, 2001Lines of potato cv. Pito transformed with the P1 gene ofPotato virus Y (PVYo) in sense or antisense orientation were evaluated for resistance to PVY in the field in 1997 and 1998. The transgenic resistance fully protected the crop from infection with PVYo transmitted by aphids in both years.

Detection and Diagnosis of PVY
2017The worldwide prevalence of Potato virus Y (PVY) poses a continuous challenge to efficient potato production. The accurate diagnosis of viruses such as PVY is inherently challenging due to the broad biological and genetic diversity of PVY strains that elicit a range of symptoms and diseases in various potato cultivars and related solanaceous species.

Diversity, Characterisation and Classification of PVY
2017Since the discovery of PVY in the 1930s, many strain groups and variants have been described although consensus on an agreed international nomenclature is still a matter of debate. The challenge for plant pathologists studying PVY remains to establish the biological significance of the genomic diversity of PVY arising from the new, diverse PVY ...

The plant of pepper (Capsicum annuum L.), is known to be infected by many viruses, resulting in economic losses at the yield in many countries worldwide. Commonly, virus infected pepper develops symptoms on the main plant parts, leading on general plant exhaustion.
