Protection against potato virus Y (PVY) in the field in potatoes transformed with the PVY P1 Gene

American Journal of Potato Research, 2001
Lines 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.

POTATO VIRUS Y (PVY) ON PEPPER IN SERBIA

Acta Horticulturae, 2002
During 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).

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)).

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.

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

Suppression effect of biological control strain to TMV and PVY

2011 6th IEEE Conference on Industrial Electronics and Applications, 2011
The suppression effect of Bacillus amyloliquefacien Ba33 against TMV and PVY by biological detect through necrotic lesions host and RNA detect through RT-PCR was studied. The result showed that the suppression ratio of necrotic lesions against TMV and PVY was 95.25% and 99.22% respectively.

Molecular diagnostics of potato infections with PVY and PLRV by immunochromatography

Moscow University Biological Sciences Bulletin, 2016
An immunochromatography test system has been developed for molecular diagnostics of the potato virus Y and PLRV infection. To increase a low yield of PLRV and raise antibodies against the PLRV antigen, chimerical virus was constructed comprising the PLRV coat protein and recombinant RNA of a tobamovirus, in which capsid protein gene was replaced by the

Response of potato, tobacco andPhysalis floridanaplants to mixed infection with PVX, PVY^NTNand PVY° strains

Canadian Journal of Plant Pathology, 2013
Abstract Post-harvest screening of potato ‘Kennebec’ revealed a Potato virus Y (PVY) incidence of 15.8%, a rate that is unusually high for a cultivar possessing a high level of field resistance to the virus. Randomly selected tubers were planted in a field plot and the resulting plants were monitored.

Résistance au PVY et nouvelles technologies

2021
Des outils biotechnologiques tels que le système Crispr-Cas9 peuvent-ils nous aider à reproduire chez la pomme de terre une forme de résistance observée chez le piment et qui empêche la multiplication des particules virales dans les cellules de la plante ? Telle est la question que se sont posée les chercheurs d’Inrae et de la FN3PT.
