ABSTRACT: Mosaic/line pattern symptoms resembling viral infections were observed on Viburnum lantanoides Michx. (Witch-Hobble, Hobblebush or Moosewood) in the Great Smoky Mountains National Park. Double stranded RNA extraction revealed the presence of multiple faint bands that were used as a template for further molecular investigation. Shotgun cloning of reverse-transcribed dsRNAs revealed the presence of genomic sequences of two phytoviruses in the original sample. Genomic segments of a putative cryptic virus showed similarities with corresponding regions of Beet cryptic viruses 2 and 3 and several other cryptoviruses. The second virus identified in this study is related, but distinct, from European mountain ash ringspot-associated virus and Fig mosaic virus (ca 40–42% identical amino acid contents of putative nucleocapsid and glycoprotein precursor), recognized species in the genus Emaravirus. Considering that emaraviruses are an emerging group of viruses associated with diseases in cultivated and wild flora, the involvement of this virus in the observed symptomatology is very plausible. Further epidemiological and etiological studies are underway.
