SUMMARY Potato virus T (PVT) infected nine species of tuber-bearing Solanum, most of them symptomlessly, and as a rule was transmitted through the tubers to progeny plants: two genotypes of S. tuberosum ssp. andigena were not infected. The virus was also transmitted by inoculation with sap to 37 other species in eight plant families. Chenopodium amaranticolor is useful as an indicator host, C quinoa as a source of virus for purification, and Phaseolus vulgaris as a local-lesion assay host… 
Properties of a resistance-breaking strain of potato virus X.
A strain of potato virus X (PVX), XHB, which failed to cause local lesions in inoculated leaves of Gomphrena globosa was found in 7% of the clones and Microprecipitin tests showed that XHB and XCP are closely related serologically.
Other Natural Hosts of Potato virus T.
Potato virus T (PVT), a member of the genus Trichovirus, was isolated from leaves of naturally infected ulluco, oca, and mashua using primers designed from the published PVT sequence.
Tests for transmission of four potato viruses through potato true seed
SUMMARY The Andean potato calico strain of tobacco ringspot virus (TRSV-Ca) was detected in 2–9% of potato seedlings grown from true seed from plants of cv. Cara and clone G5998(6) infected with
Transmission by Vectors
Three potyviruses—henbane mosaic (HMV), potato Y (PVY), and tobacco etch (TEV)—served as models in work at Rothamsted in the late 1930s that led to the definition of the so-called nonpersistent form of aphid transmission.
Natural Genes and Mechanisms for Resistance to Viruses in Cultivated and Wild Potato Species (Solanum spp.)
Together resistance to the three globally most important viruses PLRV, PVY and PVX has proved difficult, and new sources of broad spectrum resistance to viruses are required for potato breeding.
Some properties of an unusual isolate of potato virus S
An isolate confirmed as potato virus S (PVS) discovered during routine quarantine testing of potato material from the Netherlands produced unusual symptoms when inoculated on to the test plants when ELISA tests showed that it reached higher concentrations in potatoes than the Scottish isolate and when graft-inoculated onto cvs.
Host range, purification and serological properties of heracleum latent virus
HLV occurs commonly in wild plants of Heracleum sphondylium (hogweed) in Scotland without causing symptoms, and its properties resemble those of the tentative closterovirus, apple chlorotic leaf spot (ACLSV), but no serological relationship was detected to this or to any of 18 other filamentous viruses, including six definitiveClosteroviruses.
Virus and Virus-like Diseases of Potatoes and Production of Seed-Potatoes
This paper aims to provide a history of potato virus research in the United States and some of the techniques used to develop and evaluate these techniques, as well as some of their applications in other parts of the world.
Citrus Tatter Leaf Virus: A Review of its Properties and the Development of a Serological Detection System
Electron microscopic observations revealed flexuous particles 600-650 nm in length and 13 nm wide, with conspicuous cris-cross patterns when samples were stained with uranyl acetate and viewed with an electron microscope, similar to that reported for potato virus T.


Nicotiana velutina mosaic virus: purification, properties and affinities with other rod-shaped viruses.
SUMMARY Nicotiana velutina mosaic virus (NVMV), found in Australia, was transmitted by inoculation of sap to twenty species in the Solanaceae and Chenopodiaceae, and to Gomphrena globosa; its host
Two previously undescribed potato viruses from South America
Two previously undescribed viruses were identified: potato black ringspot virus (PBRV) and potato virus T (PVT) are called and described here the characterisation of the virus isolates producing these effects.
Two protein and two RNA species in particles of strawberry latent ringspot virus.
Purified preparations of strawberry latent ringspot virus (SLRV) contain a major (126S) component which tends to aggregate, and sometimes a minor component of about 58S, and the virus particles migrated as a single component both in immunoelectrophoresis tests and when electrophoresed in polyacrylamide gels.
Properties of Virus and RNA Components of Raspberry Ringspot Virus
Summary Particles of raspberry ringspot virus were homogeneous in immunoelectrophoresis tests but sedimented as three components, T, M and B, with sedimentation coefficients of 52, 92 and 130s
Optical diffraction studies of particles of potato virus T.
Summary Optical diffraction studies of electron micrographs of potato virus T particles have been made to try to understand the variation in appearance of the particles under different staining
