WebThe virus can easily be mechanically inoculated to many different hosts (34 species in 14 families). Local lesions appear in 3–4 days on Chenopodium quinoa and Gomphrena globosa, and these are followed, on Nicotiana clevelandii, Nicotiana benthamiana, and Nicotiana megalosiphon, by systemic necrotic mosaic. WebDianthoviruses utilize a −1 ribosomal frameshifting mechanism to accomplish the same result. The polymerase is further characterized by possessing no obvious helicase or methlytransferase motifs.
