Abstract: "Rose Rosette Disease (RRD) is a malady of wild and cultivated roses transmitted by the eriophyid mite Phyllocoptes fructiphilus. The causal agent of RRD which induces erratic growth in infected roses is unknown. Phytoplasma are intracellular bacteria exclusive to plant and insect species and have been identified as the causal agent for over 1000 different plant diseases. The pathol. growth of RRD, such as Witches' broom and phyllody, is also seen in some diseases caused by Phytoplasma and electron micrographs of RRD infected tissue have found spherical particles, roughly 120 to 200 nm in diam., that are not inconsistent with the size and appearance of Phytoplasma. We are testing this hypothesis using several PCR-based assays for the detection of Phytoplasma DNA in both infected rose and eriophyid mites."
