Abstract
- Fragaria (strawberry) and Rubus species (blackberry, wild blackberry, red raspberry and black raspberry) were thought to be infected with distinct isolates of Tobacco streak virus (TSV). Employing serology and nucleic acid hybridization it has been shown that these isolates form a cluster distinct from other strains of TSV. In this study we have cloned and sequenced the complete RNA 3 of an isolate of TSV from strawberry (Fragaria) as well as the coat protein (CP) gene of 14 additional isolates of TSV originating from Fragaria and Rubus species. Our data suggest that the isolates of TSV that infect Fragaria and Rubus belong to a distinct virus for which we propose the name Strawberry necrotic shock virus (SNSV). The RNA 3 of SNSV contains 2248 nucleotides, 43 more than the type isolate of TSV from white clover (TSV-WC), with a CP gene that is 669 nucleotides long, in contrast to the 714–7 nucleotides of the TSV CP sequences found in the database. The movement protein gene of SNSV is 897 nucleotides in length, 27 more than that of the TSV-WC isolate of TSV. The CP genes of the 15 Fragaria and Rubus isolates that we studied form two distinct phylogenetic clusters that share about 95% amino acid sequence identity, while they only share 60–65% amino acid sequence identity with TSV-WC.
