Potato yellow vein virus: its host range, distribution in South America and identification as a crinivirus transmitted by Trialeurodes vaporariorum
Evidence is presented that a closterovirus with a bipartite genome, potato yellow vein virus (PYVV), is associated with PYVD, which is transmitted through tubers and visual symptoms alone cannot be used to determine infection status.
Molecular resolution of a complex of potyviruses infecting solanaceous crops at the centre of origin in Peru.
Phylogenetic comparisons indicated that PTV, PVV and WPMV are the most closely related species which, together with PepMoV, PVY, Pepper yellow mosaic virus and Pepper severe mosaic virus, constitute a group that is distinguishable from other potyviruses.
Analysis of the RNA of Potato yellow vein virus: evidence for a tripartite genome and conserved 3'-terminal structures among members of the genus Crinivirus.
Pairwise comparisons and phylogeny of genome-encoded proteins showed that PYVV shares significant homology with other criniviruses but is most closely related to the Trialeurodes vaporariorum-vectored Cucumber yellows virus.
Reaction of potato varieties toPotato mop-top virus infection in the andes
The effects of PMTV on field-grown plants at three locations in the Peruvian Andes where the virus and its fungal vector,Spongospora subterranea, are endemic was examined to examine the response of U.S. cultivars to PMTV infection.
Molecular variation of Potato yellow vein virus isolates
It is suggested that there is low genetic diversity in the PYVV isolates examined and that the Peruvian isolate of PyVV may have originated in Colombia.
Evidence for heterologous encapsidation of potato spindle tuber viroid in particles of potato leafroll virus.
Spread of potato spindle tuber viroid (PSTVd) to potato clone DTO-33 from source plants doubly infected with potato leafroll virus (PLRV) and PSTVd was shown to be of the persistent type and transmission did not occur when the insects were allowed to feed on singly infected plants.
A novel luteovirus from sweet potato, sweet potato leaf speckling virus.
A virus obtained from accession DLP 1541 of the International Potato Center (CIP) sweet potato germplasm collection was shown to induce a curling and a white speckling of the leaves of infected plants, which suggests that SPLSV should be classified in the genus Luteovirus.
Conservation of coat protein sequence among isolates of potato mop-top virus from Scotland and Peru
Coat protein gene sequences of eight isolates of potato mop-top virus from the Peruvian Andes and from Scotland were compared and there was little sequence variation among all isolates.
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 new plant virus from the high jungle of the Eastern Andes; Solanum apical leaf curling virus (SALCV)
A previously undescribed plant virus, Solanum apical leaf curling virus (SALCV), was found in cultivated potato and indigenous wild solanaceous plants in an area of high jungle near San Ramon, Peru and suggests possible affinities with geminiviruses.
