Synonyms for dianthovirus or Related words with dianthovirus
Examples of "dianthovirus"
is a genus of viruses, in the family Tombusviridae. Dianthoviruses are plant viruses. There are currently three species in this genus including the type species Carnation ringspot virus. 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 hosts with previously uninfected host.
are non-enveloped, with icosahedral and spherical geometries, a “hexagonal” appearance, and T=3 symmetry. The diameter is around 28-34 nm. Genomes are linear and segmented, bipartite, around 11.3-1.4kb in length. The buoyant density in CsCl of virions is between 1.363-1.366 g cm-3. They have a sedimentation coefficient of 126-132-135 S20w. The pH of their isoelectric point is 4.5. The virions become inactive from about 80-90 °C and are inactive above those temperatures. They are viable in vitro for about 50–70 days. Treatment with ether either decreases or does not alter their infectivity. No lipids have so far been reported.
BTE has been found to bind to eIF4G and weakly to eIF4E (proteins involved in translation initiation). BTE allows translation initiation of an mRNA without a 7mG cap (required for translation in most eukaryotic mRNA). Other forms of cap-independent translation elements (CITE) exist (primarily in plant viruses from the Luteovirus, Necrovirus,
and Umbravirus genera of plantviruses, but also in some host mRNA; notably many heat shock mRNA lack a 7mG cap but are still translated). The general purpose of BTE and these other CITE's is to get the ribosome to begin translation without the 7mG cap. In the case of BTE it "tricks" eIF4F (eIF4E, eIF4G are parts of eIF4F) into "telling" the ribosome that a 7mG cap is present.
