Occurrence of the Redglobe strain of Grapevine leafroll-associated virus 2 in table and wine grape varieties in Italy

摘要

The Redglobe strain of Grapevine leafroll-associated virus 2 (GLRaV-2-RG) is a recently discovered closterovirus so far reported to infect solely cv. Redglobe. A survey for this virus 2 in about 380 accessions of table and wine grape varieties conducted during 2001-2003 proved that GLRaV-2-RG was present also in other table grape varieties, though to a smaller extent, while it was never detected in wine varieties.
