Aphid Feeding Behavior in Relation to Potato Virus Y (PVY) Acquisition

Journal of Economic Entomology, 2012
Potato virus Y (PVY) is transmitted by aphids in a nonpersistent manner and aphid species differ in their ability to transmit PVY. During host selection, aphids will land and probe on nonhost plant species and this behavior is an important component of the epidemiology of many aphid-transmitted viruses.

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.

Nucleotide sequence of the capsid protein gene of potato virus Y (PVY)

Virus Genes, 1988
The nucleotide sequence of the 3' terminal region of potato virus Y (PVY) was determined. Starting with a poly(A) tail of 18 residues a non-coding region of 335 nucleotides precedes the region encoding for the virus coat protein (cp) 801 nucleotides long ending with a TGA.

Comparative evaluation of resistance to potato virus Y (PVY) in three different RNAi-based transgenic potato plants

Transgenic Research, 2022
Small interfering RNAs (siRNAs) produced from template double-stranded RNAs (dsRNAs) can activate the immune system in transgenic plants by detecting virus transcripts to degrade. In the present study, an RNA interference (RNAi) gene silencing mechanism was used for the development of transgenic potato plants resistant to potato virus Y (PVY), the most

Development of longer pepper resistant lines to Potato Virus Y (PVY)

2014
Pepper (Capsicum annuum L.), is one of the most important vegetable species produced both in the world and in Turkey. Turkey is in third place in pepper production in the world. There are many viruses affecting and limiting pepper production. Potato Y virus (PVY), a member of the genus potyvirus, is one of the most common viruses infecting pepper crops.

Production of Potato Genotypes with Resistance to Potato Virus Y (PVY) by Biotechnological Methods

1999
In potato breeding crossing programmes are performed for the incorporation of desirable traits of related potato species into the genepool of a given potato variety. For example, derivatives from Solanum demissum have been utilised in 77% of all foreign gene introgressions carried out in the European cultivars because of its resistance to late blight ...

Solanum elaeagnifolium, a potential source of Potato virus Y (PVY) propagation*

EPPO Bulletin, 2007
In the context of an epidemiological study on Potato virus Y (PVY) in potato crops, Solanum elaeagnifolium Cav. was included in the weeds prospected. Surveys were carried out in four seed potato areas: Cap Bon, Manouba, Jendouba and Kairouan. S. elaeagnifolium was found in all areas, except Cap Bon.

[Potato virus Y (PVY): from its discovery to the latest outbreaks].

Virologie (Montrouge, France)
Potato virus Y (PVY, family Potyviridae, genus Potyvirus) is one of the most economically important viruses infecting potato. This plant virus is transmitted by aphids and is present in all potato growing areas across the world. Thanks to the steady set-up of biological, serological and molecular detection/characterization tools, PVY potato strain ...

The Value of Crop Borders for Management of Potato Virus Y (PVY) in Seed Potatoes

2006
Potato virus Y (PVY) is a very serious problem throughout most major seed potato producing states. Seed potato producers in Minnesota and North Dakota were surveyed in early 2005 to assess their perception of the profitability and risks associated with using crop borders to manage PVY in seed lots. Twenty-three producers responded (a 25% response rate),
