A novel virus genome discovered in an extreme environment suggests recombination between unrelated groups of RNA and DNA viruses. Biol Direct. 2012;7:13.Diemer, G.S.; Stedman, K.M. A novel virus genome discovered in an extreme environment suggests recombination between unrelated groups of RNA ...
bunya viruses,rotavirus,arena virus, and other reoviruses. Most DNA viruses carry a double stranded genome, with an exception beingparvoviridaeKok and Pechere (1999). Other classifications for viruses are based on the polarity of the genomes, type ofnucleocapsid, or shape of the viral particle....
Intracellular DNA sensors, such as cyclic GMP–AMP synthase (cGAS) and IFNγ-inducible protein 16 (IFI16), detect viral DNA in the cytoplasm and/or nucleus and signal through the stimulator of IFN genes (STING) to trigger an immune response. Viruses antagonize PRRs through the sequestration or...
Intercellular transport and access to the phloem is mediated via plasmodesmata. To facilitate the transfer of the viral genomes to neighboring cells, RNA viruses produce proteins interacting with and modifying plasmodesmata [41,42]. This is achieved with the assistance of so-called viral-encoded ...

and complex genome cannot be self-sufficient. Yet, there are similar examples among DNA viruses: the members ofLavidaviridae(also known as virophages) have genome sizes comparable to that of Ostravirus (17–30 kb, 20 predicted ORFs) and can develop in their protist hosts only in the ...

Abstract:Viruses with double-stranded RNA genomes form isometric particles or are capsidless. Here we report a double-stranded RNA virus, Colletotrichum camelliae filamentous virus 1 (CcFV-1) isolated from a fungal pathogen, that ...
RNA Directed DNA Polymerase In subject area: Pharmacology, Toxicology and Pharmaceutical Science Reverse transcriptase (RT), also known as RNA-dependent DNA polymerase, is a DNA polymerase enzyme that transcribes single-stranded RNA into DNA. From: Encyclopedia of Biological Chemistry (Second ...
