Genomic evidence of intraspecific recombination in sugarcane mosaic virus

Sugarcane Mosaic Virus-Based Gene Silencing in Nicotiana benthamiana

Background:Potyvirus-based virus-induced gene silencing (VIGS) is used for knocking down the expression of a target gene in numerous plant species. Sugarcane mosaic virus (SCMV) is a monopartite, positive single strand RNA virus. Objectives:pBINTRA6 vector was modified by inserting a gene segment of SCMV in place of Tobacco rattle virus (TRV) genome part 1 (TRV1 or RNA1)...

Patterns of recombination in turnip mosaic virus genomic sequences indicate hotspots of recombination.

Potyviruses have variable single-stranded RNA genomes and many show clear evidence of recombination. This report studied the distribution of recombination sites in the genomes of 92 isolates of the potyvirus Turnip mosaic virus (TuMV); 42 came from the international gene sequence databases and an additional 50 complete genomic sequences were generated from field samples collected in Europe and ...

Role of RNA structure in non-homologous recombination between genomic molecules of brome mosaic virus.

Brome mosaic virus (BMV) is a tripartite genome, positive-sense RNA virus of plants. Previously it was demonstrated that local hybridization between BMV RNAs (RNA-RNA heteroduplex formation) efficiently promotes non-homologous RNA recombination. In addition, studies on the role of the BMV polymerase in RNA recombination suggested that the location of non-homologous crossovers depends mostly on ...
