Production of cucumber mosaic virus RNA5 and its role in recombination

Production of cucumber mosaic virus RNA5 and its role in recombination.

Cucumber Mosaic Virus (CMV) is a plant infecting tripartite positive-strand RNA virus. In addition to three genomic and two known subgenomic RNAs, CMV strains of subgroup II (e.g. Q-CMV), but not subgroup I (e.g. Fny-CMV), produce and package a redundant RNA5 encompassing the 3' 304-307 nucleotides of RNAs 2 and 3. The mechanism regulating RNA5 production and its role in CMV life cycle is unkno...

Structural and functional characterization of the 59 region of subgenomic RNA5 of cucumber mosaic virus

Received 4 February 2008 Accepted 8 March 2008 The uncapped and ORF-less subgenomic RNA5 is produced in subgroup II strains of cucumber mosaic virus (CMV), but not in subgroup I strains. Its initiation nucleotide (nt 1903) is in a 21 nt conserved sequence (Box1) that is absent in CMV subgroup I. Putative non-coding RNA structural elements surrounding Box1 in the plus and minus strand were ident...

Structural and functional characterization of the 5' region of subgenomic RNA5 of cucumber mosaic virus.

The uncapped and ORF-less subgenomic RNA5 is produced in subgroup II strains of cucumber mosaic virus (CMV), but not in subgroup I strains. Its initiation nucleotide (nt 1903) is in a 21 nt conserved sequence (Box1) that is absent in CMV subgroup I. Putative non-coding RNA structural elements surrounding Box1 in the plus and minus strand were identified in silico and by in vitro RNase probing. ...

Characterization of Cucumber Mosaic Virus From Mint in Tehran Province

Cucumber mosaic virus (CMV) is one of the causal agents of viral diseases that infected mint (Mentha spp.). CMV is a member of the cucumovirus genus in  Bromoviridae family. The virus is naturally transmitted by aphids in a non-persistent manner.During  growing season 2007-2008, leaf samples from plants of mint fields with symptoms of viral disease were collected in mint fieldas in Tehran provi...
