Strawberry latent virus: a potential link between plant and insect viruses. Phytopathology. 95:S106. Interpretive Summary: Technical Abstract: More than two decades ago, a number of laboratories studied strawberry mild yellow edge disease (SMYED) and tried to verify the presence of a luteovirus that was anecdotally associated with it. Martin and Converse purified a spherical virus from a SMYE diseased plant, but later found similar particles in SMYE-free plants, including seedlings, that remained asymptomatic. One of the strawberry clones used in that study was used for the characterization of the unknown spherical virus. Cloning dsRNA obtained from the plant revealed the unique properties of the virus, designated as Strawberry latent virus (StLV). StLV is closely related to members of the Cripavirus genus, viruses that cause devastating insect diseases. Sequence and phylogenetic analysis indicated that StLV is also related to picorna-like plant viruses belonging to the Sequiviridae family. The ability to purify the virus indicates that StLV can multiply in strawberry while the complete nucleotide sequence will reveal the mechanisms of movement in the plant that may resemble those of cryptic viruses. |
