Detection of cucumber mosaic virus RNA5 by hybridization with photobiotin-labelled double-stranded RNA5 probe.

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. ...

Simultaneous Detection of Arabis Mosaic Virus, Cherry Leafroll Virus and Cucumber Mosaic Virus with Coamplification of Plant mRNA as Internal Control for Olive Certification Programs

Background and Aims: Certification programs of plant propagating materials rely on faster, cheaper and more importantly sensitive and reliable methods for detection of systemic pathogens as indicated in national and/or international health standards of plant propagating materials. Reverse transcription-polymerase chain reaction (RT-PCR) has been documented as an alternative assay for certific...
