A new poty-like virus was isolated from plants of winter daphne (Daphne odora) that showed virus-like symptoms on leaves, from four regions of Korea during 2014. Filamentous-shaped particles were observed by transmission electron microscopy of preparations extracted from symptomatic leaves and examined by the direct negative stain method. RT-PCR assay showed that three samples were positive for both Cucumber mosaic virus and potyvirus, and only one sample was positive for potyvirus only. A BLAST comparison to partial sequences from helper-component proteinase, cylindrical inclusion and coat protein genes detected the highest nucleotide identity of 76%, 72%, and 72% with Daphne mosaic virus, respectively, levels below the potyvirus species discrimination threshold. The new potyvirus was isolated using indicator plants (Chenopodium amaranticolor), in which local lesions were produced. In this study, we identified a novel potyvirus from winter daphne, which we have named Daphne mottle virus (DapMoV).
