Abstract

Three rhabdovirus isolates (R, H and S) from strawberry were studied for symptoms on indicator plants (Fragaria vesca UC-4, UC-5 and UC-6 and F. virginiana UC-10, UC-11 and UC-12). On the basis of the characteristics of reactions and symptoms on indicator plants. isolate R was classified as a typical strawberry crinkle virus (SCrV), and isolates H and S as typical strawberry latent C virus (SLCV). Electron microscopy of cells infected with the above three isolates and SLCV maintained in Oregon State University (SLCV-0) revealed the presence of rhabdoviruslike particles of about the same size, and viroplasms for all isolates. In cells infected with the isolate R, virus particles and viroplasms were consistently observed to accumulate in the cytoplasm. In contrast, cells infected with isolates H. S and SLCV-O appeared to contain mature particles predominantly in the perinuclear space and immature particles and viroplasms in the nuclei. These findings indicate the evidence of two distinct rhabdoviruses in strawberry; one is the cytoplasm-associated SCrV and the other is the nucleus-associated SLCV.
