Cellular origins of dsRNA, their recognition and consequences

WebDec 23, 2008 · We investigated if Wolbachia protection extends to infections by two other RNA viruses and a DNA virus. Nora virus is a recently described common natural pathogen of D. melanogaster [ 49 ]. Similar to D CV, Nora virus is a small, non-enveloped virus with a single-stranded, positive-sense RNA genome. WebIn all RNA viral infections, formation of replication complexes and compartments follows the onset of viral protein synthesis, and replication of the viral genome begins with the formation of the complementary strand to act as a template for the synthesis of the genomic RNA. 65 Progeny virions are assembled from replicated genomes, viral proteins, … An RNA virus is a virus—other than a retrovirus—that has ribonucleic acid (RNA) as its genetic material. The nucleic acid is usually single-stranded RNA (ssRNA) but it may be double-stranded (dsRNA). Notable human diseases caused by RNA viruses include the common cold, influenza, SARS, MERS, Covid-19, … See more Single-stranded RNA viruses and RNA Sense RNA viruses can be further classified according to the sense or polarity of their RNA into negative-sense and positive-sense, or ambisense RNA … See more Animal RNA viruses are classified by the ICTV. There are three distinct groups of RNA viruses depending on their genome and mode of replication: • Double-stranded RNA viruses (Group III) contain from one to a dozen different RNA molecules, each … See more Classification is based principally on the type of genome (double-stranded, negative- or positive-single-strand) and gene number and organization. Currently, there are 5 orders and 47 families of RNA viruses recognized. There are also many unassigned species … See more With the exception of the Hepatitis D virus, this group of viruses has been placed into a single phylum—Negarnaviricota. This phylum has been divided into two subphyla— See more Numerous RNA viruses are capable of genetic recombination when at least two viral genomes are present in the same host cell. Very rarely viral RNA can recombine with host RNA. RNA recombination appears to be a major driving force in determining genome … See more There are twelve families and a number of unassigned genera and species recognised in this group. • Family Amalgaviridae • Family Birnaviridae See more There are three orders and 34 families recognised in this group.
