Two previously undescribed potato viruses from South America

  author={L. F. Salazar and Bryan D. Harrison},
THE proneness of potatoes (Solanum spp.) to virus diseases is well known, and about 20 viruses are recorded in naturally infected potatoes in Europe and North America1,2. Many of these viruses also occur in the Andean region of South America. For example, in Peru several well known viruses were detected3 in ‘basic seed’ stocks by inoculating sap to a range of indicator species and by serological tests. Some indicator plants in these tests, however, developed symptoms unlike those typical of… 
Host range and properties of potato black ringspot virus
SUMMARY Potato black ringspot virus (PBRV), obtained from cultivated potato in Peru, was found to have a very wide host range resembling that of tobacco ringspot virus (TRSV-B), to which PBRV is
Host range, purification and properties of potato virus T
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.
A check-list of new host plants for identification and separation of twelve potato viruses
The detected 384 species of plants, previously unknown as hosts of potato viruses, among 49 genera belonging to 15 families, among which 70 had not been tested before in plant-virological experiments and the remainder were shown for the first time to be indicator plants for certain viruses.
The occurrence, hosts and properties of lilac chlorotic leafspot virus, a newly recognised virus from Syringa vulgaris
The infrequent occurrence of LCLV in lilac in S.E. England indicates that the virus could probably be eradicated by selecting only virus-free plant material for propagation, and the virus showed no serological relationship to any of six closteroviruses.
The closteroviruses: a distinct group of elongated plant viruses.
Of the 10 typical closteroviruses, six are described, and purification methods for three are presented that enabled their partial characterization, and it is possible to visualize the origin of the heavier genomes via dimerization of the half-size units.
Nepoviruses: General Properties, Diseases, and Virus Identification
This virus, later known as tobacco ringspot virus (TRSV), induced necrotic rings in inoculated leaves of tobacco and in the first leaves to be invaded systemically; leaves produced subsequently showed little evidence of infection, although they too contained the virus.
The relationship of potato black ringspot virus to tobacco ringspot and allied viruses
PBRV and tobacco ringspot virus should be considered separate viruses, and that TRSV-P should be thought of as a strain of PBRV.
Pest categorisation of non‐EU viruses and viroids of potato
These viruses do not meet the criteria assessed by EFSA to qualify as potential Union regulated non‐quarantine pests and for most of the categorised viruses, the conclusions have inherent uncertainties.
Pest categorisation of non‐EU viruses and viroids of Prunus L.
Non‐EU viruses, especially those recently discovered, do not meet the criteria assessed by EFSA to qualify as potential Union regulated non‐quarantine pests.
The complete nucleotide sequence of potato virus T
The viral genome resembles that of trichoviruses but is smaller and does not contain the 3′ terminal fourth ORF found in some members of this genus, which may represent a new genus of plant viruses.


Sixteen groups of plant viruses.
Names are proposed for twelve of the groups of plant viruses and it is suggested that the value of these names should be tested by using them for an experimental period.
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
