Английский. During 2001, in the Aegean Greek islands of Rodi and Kastellorizo, wild castor bean plants (Ricinus communis L.), showing yellowish vein netting and mottling of the leaves, were observed. A virus was isolated by mechanical inoculation from such plants to herbaceous hosts, which, based on biological, serological and molecular assays, was identified as an isolate of Olive latent virus 2 (OLV-2/CB), virtually indistinguishable from the type strain. The field syndrome was experimentally reproduced in artificially inoculated castor bean seedlings and the virus reisolated, thus fulfilling Koch's postulates. This is the first report of OLV-2 outside Italy in a natural host other than olive

[Nel 2001, nelle isole greche di Rodi e Kastellorizo, piante selvatiche di ricino (Ricinus communis) hanno evidenziato maculature e venature giallastre delle foglie. E' stato isolato un virus da ogni pianta e con prove biologiche, sierologiche e molecolari e' stato identificato come ceppo di Olive latent virus 2 (OLV-2/CB), virtualmente indistinguibile dal ceppo standard. Le alterazioni osservate in campo sono state riprodotte sperimentalmente in plantule di ricino inoculate artificialmente e il virus e' stato reisolato, con rispondenza ai postulati di Koch. Questo e' la prima segnalazione relativa a OLV-2 fuori Italia in un ospite naturale diverso dall'olivo]
