Probable geographical grouping of PVYN and PVYNTN based on sequence variation in P1 and 5′-UTR of PVY genome and methods for differentiating North American PVYNTN

Journal of Virological Methods, 2002
An increasing number of countries in recent years have reported the occurrence of potato tuber necrotic ringspot disease (PTNRD), caused by tobacco veinal necrosis strain of Potato virus Y (PVY(N)), belonging to the sub-group tuber necrosis (PVY(NTN)).

Potato virus Y (PVY) in Seed Potato Certification

Journal of Plant Diseases and Protection, 2015
In the EU and many other countries worldwide, seed potatoesrequire certification to be marketed. In most of the Europeannational and international seed potato regulations, the tolerances for viruses are at present based on a combinationof virus incidence and symptom severity.

Inhibition of potato virus Y NIa activity: preparation of monoclonal antibody directed against PVY NI protein that inhibits cleavage of PVY polyprotein

Archives of Virology, 2001
A partially purified nuclear inclusion (NI) fraction was obtained from tobacco plants infected by potato virus Y (PVY). Four monoclonal antibodies (MAbs) were produced and characterized using this semipurified fraction as antigen. Data showed that only one was directed against NIa whereas two were directed against cytoplasmic inclusion (CI) protein and

Improvement of Potato virus Y (PVY) detection and quantitation using PVYN- and PVYO-specific real-time RT-PCR assays

Journal of Virological Methods, 2006
A Potato virus Y (PVY) single nucleotide polymorphism (A/G(2213)), recently identified as a molecular determinant of the tobacco leaf necrosis symptom induced by PVY(N) isolates, has been used as a target to develop two PVY group-specific (PVY(N) and PVY(O)) fluorescent (TaqMan-based) real-time RT-PCR assays.

Serological Analysis and Coat Protein Sequence Determination of Potato Virus Y (PVY) Pepper Pathotypes and Differentiation from Other PVY Strains

European Journal of Plant Pathology, 1999
The serological relationships of Potato Virus Y (PVY) isolates belonging to the pepper pathotypes 0, 1 and 1-2 were established by enzyme-linked immunosorbent assay (ELISA). PVY pepper pathotypes did not react with monoclonal antibodies which typically recognize non-pepper strains within the PVY group, leading to discrimination between these two groups

Divergent effects of PVY-infected potato plant on aphids

European Journal of Plant Pathology, 2010
Host plant selection by aphids can be positively or negatively affected when plants are infected by phytoviruses. Potato plants infected by Potato virus Y (PVY), a non-persistent virus, are reported to affect settling behaviour and growth parameters of Myzus persicae Sulzer and Macrosiphum euphorbiae Thomas.

Epidemiology and Field Control of PVY and PLRV

2001
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 Potato leafroll virus (PLRV) are the most common of the 28 viral diseases known to infect potato (Salazar, 1996).

PVY: An Old Enemy and A Continuing Challenge

American Journal of Potato Research, 2012
Potato virus Y (PVY) is one of the most important viruses affecting potato production worldwide. The virus has been extensively studied for several decades, yet considerable economic losses continue to be suffered by the potato industry around the world.

Differentiating PVYNTN from PVYN by annealing to reference RNA transcripts

Journal of Virological Methods, 2001
A method for the differentiation of virus strains based on the shift in electrophoretic mobility of partially annealed RNA transcripts is described. Oppositely oriented RNA transcripts of the NTN- and N-strains of PVY, complementary at their 3'-end variable (strain-specific) region, were annealed to form a partial duplex which moved more slowly in gel ...
