Identification of Cucumber Mosaic Virus from Vinca minor in New Jersey. Diane B. Smith, Former Graduate Research Assistant, Department of Plant Pathology, Cook College, New Jersey Agricultural Experiment Station, Rutgers University, New Brunswick 08903. Robert F. Davis, Assistant Professor, Department of Plant Pathology, Cook College, New Jersey Agricultural Experiment Station, Rutgers University, New Brunswick 08903. Plant Dis. 70:1056-1059.

Mild mosaic, chlorosis, and distortion symptoms were observed on leaves of Vinca minor in Somerset, NJ. A virus was isolated from these plants and identified as cucumber mosaic virus (CMV) based on host reactions, aphid transmissibility in a nonpersistent manner, icosahedral particle morphology, molecular weight of 29,000 Da of coat protein subunits, and serological relationships. This isolate is designated CMV-Vi. Mouse ascites fluid produced to CMV-Vi gave specific and sensitive reactions in ELISA and Ouchterlony gel double-diffusion tests. Field surveys indicated that CMV is present throughout New Jersey in V. minor.
