IDENTIFICATION OF THE ROSE ROSETTE DISEASE AGENT

P.L. Di Bello, T. Ho, I.E. Tzanetakis
Rose rosette disease (RRD) was first described in the 1940s, and is the most important virus disease of rose in the United States. A new emaravirus, Rose rosette virus (RRV) was characterized, and found in perfect association with RRD. Past research has established that the RRD agent is spread by the eriophyid mite Phyllocoptes fructiphilius, and we were recently able to detect RRV in mites. Viruliferous mites were individually collected from RRV-infected roses, and transferred to RRV-free roses. Two months post-infestation, typical RRD symptoms developed, and material tested positive for RRV. Total nucleic acids from diseased material were subjected to deep sequencing. No other viruses were detected in the RRD material proving that RRV causes the disease. Additional RRV genomic fragments were also discovered.
