Dianthoviruses
WebJun 4, 2024 · Dianthoviruses belong to the Tombusviridae family and have a bipartite positive-sense single-stranded RNA genome consisting of RNA1 and RNA2 . A recent study described the accumulation of a noncoding viral RNA, SR1f RNA, during dianthovirus infection, generated from the 3′ UTR of viral RNA1 through an unexplored mechanism of … 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. In this description, as well as those for each genus, the polymerase is labeled as a single ORF with the readthrough (RT) portion labeled ORF1 …

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.

Web2.1 CRSV. Symptoms such as leaf mottling and ringspotting, plant stunting, and flower distortion persist after the infection of Dianthus caryophyllus and D. barbatus by CRSV. CRSV probably occurs worldwide, wherever Dianthus species are grown. Virions are distributed in all parts of the infected plant, including in the cell cytoplasm and nuclei. Dianthovirus is a genus of viruses, in the family Tombusviridae. Dianthoviruses are plant viruses. There are three species in this genus. The virus probably has a worldwide distribution, and can be transmitted via nematodes, by mechanical inoculation, by grafting of plants and by contact between infected … See more The genus contains the following species: • Carnation ringspot virus • Red clover necrotic mosaic virus • Sweet clover necrotic mosaic virus See more Viral replication is cytoplasmic.
