Among them, two poty viruses have been detected: daphne Y virus in New Zealand, with a particle length of 733 nm , and a second virus, also named daphne Y virus, in Germany, with particles of 750 nm in length and serologically related to turnip mosaic virus . The filamentous virus found in the Czech Republic has particles of modal length equal to 696 nm and induces the formation of inclusion bodies that are identical to those of the German isolate, but it is not mechanically transmissible to Chenopodium quinoa and C amaranticolor, in contrast to the German potyvirus. We named the Czech virus Daphne mosaic virus (DapMV), characterised it thoroughly, and based on the nucleotide sequence of the coat protein (CP) gene, proposed it to be a member of a new species of the genus Potyvirus . Here, we report the complete sequence of DapMV and its sequencerelationships. 收起
