Cryphonectria is a fungal genus associated with economically significant disease of trees Herein we characterized a novel doublestranded RNA virus from the fungal species Cryphonectria naterciae, a species unexplored as a virus host De novo assembly of RNAseq data and Sanger sequencing of RACE (rapid amplification of cDNA ends) clones gave the complete, nonDoublestranded RNA viruses need to carry an RNAdependent RNA polymerase (RdRp) inside their virion to the host in order to be able to replicate their genome We characterized the hPBV RdRp enzymatically and structurally and revealed the similarities of this RdRp to the other known small dsRNA virus RdRps like phi6 RdRp, which has beenUnique among the RNA viruses are the retroviruses, whose replication involves a doublestranded DNA phase, making these viruses an easy target for genetic manipulation Transfection of fulllength cDNA molecules leads to the establishment of replicating virus particles and integration of the viral genetic information into the host genome ( 10 )

RNA virus A virus in which the genetic material is RNA The RNA may be either double or singlestranded There are 6 classes of viruses The DNA viruses constitute classes I and II The RNA viruses make up the remaining classes Class III viruses have a doublestranded RNA For Example Parvo Virus, ?174 Virus RNA Virus RNA Viruses are those Viruses that contain RNA viral Genome RNA Viruses are furtherly subdivided into two classes on the basis of either Single Strand RNA Genome or Double Strand RNA Genome Doublestranded RNA virus These Viruses are such Viruses that contain Double Strand RNA Genome in CapsidSufficient yield for use in the chosen doublestranded cDNA conversion method Table 1 Extraction kits tested internally at Illumina Product name Vendor Catalog no For targeting RNA viruses QIAmp Viral RNA Mini Kit (50 samples) QIAGEN QIAmp Viral RNA Mini Kit (250 samples) QIAGEN For targeting DNA and RNA viruses
Mammalian reovirus is a nonenveloped doublestranded RNA virus Although isolated from respiratory and enteric tracts, reovirus is rarely linked to human disease and is thus regarded as benign Recently, reovirus was found to preferentially kill many types of cancer cells, raising the prospect of using reovirus as a cancer therapy reagent Nuclear RNA virusencoded miRNAs A virus with an RNA genome is named an RNA virus, which depending on the type of genome can be subdivided into doublestranded RNA (dsRNA), positivesense singlestranded RNA (ssRNA ) and negativesense singlestranded RNA (ssRNA −)Various families of RNA viruses exist, including Retroviridae, Orthomyxoviridae, The RNA structures are potential targets for the development of drugs against the virus The results were published on 10 November as
List 6 major diseases caused by RNA viruses; Negative strand RNA viruses have a unique mechanism of replication Their genome is a single strand RNA that has to be transcribed as soon as the virus enters the host in order to carry out viral replication As a result, a viralspecific RNA polymerase is packaged in the virion and is ready for transcription after virus entry They are the negative or minus (−)strand RNA viruses, the closely related ambisense RNA viruses, and doublestranded RNA viruses (Table 102 and Box 102) For each of these groups of viruses, the first synthetic event after genome penetration is
