Some properties of an unusual isolate of potato virus S

Evidence for the Role of Subgenomic RNAs in the Production of Potato Virus S coat Protein During in Vitro Translation

“…la). This correlates well with previously published particle length measurements of purified virus (Koenig, 1982) and virus particles found in leaf dips (Rose, 1983).…”

Transgenic Nicotiana debneyii expressing viral coat protein are resistant to potato virus S infection

“…Rose (1983) found that inoculation of N. debneyii with the symptomless CE strain of PVS could crossprotect against subsequent inoculation with PVS O which normally produces chlorosis of the upper leaves. It has been postulated that one of the underlying mechanisms of cross-protection is that the presence of coat protein from the first virus acts to inhibit the uncoating of the second challenge virus or that it encapsidates the RNA of the challenging strain thereby preventing its replication.…”

Analysis of Iranian Potato virus S isolates

“…Most PVS isolates do not cause symptoms on the majority of potato cultivars, with occasional mild leaf symptoms of rugosity, vein deepening and leaf bronzing. However, on susceptible cultivars such as Pentland Javelin and Epicure, some isolates cause more severe symptoms [27]. In addition, serological assay using monoclonal antibodies [2] and molecular variability based on CP gene were also used to distinguish between PVS O and PVS A strains [3,17].…”
