SEROLOGICAL RELATIONSHIP OF BLUEBERRY RED RINGSPOT VIRUS

A positive serological relationship was established between an isolate of blueberry red ringspot virus (BBRRSV) and the cabbage B strain of cauliflower mosaic virus (CaMV) by enzyme-linked immunosorbent assay (ELISA) and by immunosorbent electron microscopy (ISEM). In reciprocal tests, anti-BBRRSV rabbit and mouse immunoglobulins and anti-CaMV rabbit and mouse immunoglobulins gave positive ELISA absorbance (A₄₀₅) values with partially purified preparations of both viruses, except when anti-CaMV immunoglobulin was used to trap BBRRSV. Homologous and heterologous ISEM decoration was provided by both mouse immunoglobulins for both viruses.
These data show that BBRRSV is serologically related to but not identical with CaMV, the type member of the caulimovirus group.
