Engineered resistance in potato against potato leafroll virus, potato virus A and potato virus Y
Virus Genes, 2013Transgenic potato plants of Solanum tuberosum cultivar Vales Sovereign were generated that expressed fused, tandem, 200 bp segments derived from the capsid protein coding sequences of potato virus Y (PVY strain O) and potato leafroll virus (PLRV), as well as the cylindrical inclusion body coding sequences of potato virus A (PVA), as inverted repeat ...

Journal of Phytopathology, 2001
Potato leafroll virus (PLRV) and potato spindle tuber viroid (PSTVd) are important pathogens affecting the potato (Solanum tuberosum L.). PLRV is transmitted only by aphids, Myzus persicae being its principal vector. In contrast, PSTVd is transmitted by foliar contact and true seeds, but is not aphidâtransmissible.

Spread and Control of Potato Leafroll Virus in Minnesota
Journal of Economic Entomology, 1989We compared importance of green peach aphid, Myzus persicae (Sulzer), and potato aphid, Macrosiphum euphormae (Thomas), apterae and alatae in secondary spread of potato leafroll virus (PLRV) and the control achieved with foliar sprays alone to that of conventional practice using a soil systemic. Density gradients of apterae were produced by application

Purification and characterization of potato leafroll virus
Virology, 1979Potato leafroll virus (PLRV) was purified from infected potato (Solanum tuberosum L.) with yields of 0.4-0.6 mg/kg of foliage. The virus sedimented as a single component of 127 S. An antiserum prepared against purified virus had a maximum titer of 1:1024 in agar gel double diffusion tests.

Chimeric Virus as a Source of the Potato Leafroll Virus Antigen
Molecular Biotechnology, 2017Large quantities of potato leafroll virus (PLRV) antigen are difficult to obtain because this virus accumulates in plants at a low titer. To overcome this problem, we constructed a binary vector containing chimeric cDNA, in which the coat protein (CP) gene of the crucifer infecting tobacco mosaic virus (crTMV) was substituted for the coat protein gene ...

Volunteer potatoes as a source of potato leafroll virus and potato virus X
American Potato Journal, 1981Volunteer potatoes were investigated as infection sources for potato leafroll virus (PLRV) and potato virus X (PVX) in a high elevation seed potato growing area of eastern Idaho. Population densities ofMyzus persicae were assessed. Percentage of PLRV and PVX infection of the volunteers and seed potato crops was determined, as well as density of ...

Purification and electron microscopy of potato leafroll virus
Virology, 1969A procedure for purification of potato leafroll virus (PLRV) from its plant host was improved. An extract from diseased Physalis floridana plants was emulsified with an n-butanol-chloroform mixture. The virus in the aqueous phase was concentrated by centrifugation, the pellet was resuspended in 0.01 M phosphate buffer and subjected to emulsification ...

Ultrastructure of potato leaf phloem infected with potato leafroll virus
Virology, 1980Electron microscopy of Russet Burbank potato (Solanum tuberosum L.) leaf midveins infected with the potato leafroll virus (PLRV) revealed the pathological effects induced by the virus in the phloem. Virus particles were observed in mature sieve elements, companion cells, and plasmodesmata connecting the two kinds of cells.

Host range of potato leafroll virus
American Potato Journal, 1953The susceptibility to potato leafroll virus of over 150 species distributed among 39 families was determined. Inoculations were made by means of the peach aphid,Myzus persicae. The species considered susceptible are those from which the virus could be recovered 3 to 6 weeks following inoculation.
