RNA-RNA recombination is an important pathway in virus evolution and has been described for many viruses. However, the factors driving recombination or promoting the selection of recombinants are still unclear. Here, we show that the small movement protein (2b) was able to promote selection of RNA 1/2-RNA 3 recombinants within a chimeric virus having RNAs 1 and 2 from cucumber mosaic virus, and...

Bu çalışma, 2017 yılında Türkiye’nin farklı illerindeki üreticilerden ve firmalardan temin edilen bakla, bezelye, mercimek nohut tohum örneklerinde Alfalfa mosaic alfamovirus (AMV), Bean yellow potyvirus (BpYMV), Cucumber cucumovirus (CMV) Pea seed-borne (PSbMV) virüslerinin bulunma durumunun belirlenmesi tespit virüslerin biyolojik moleküler karakterizasyonunun yapılması amacıyla gerçekleştiri...

For the cell-to-cell movement of cucumoviruses both the movement protein (MP) and the coat protein (CP) are required. These are not reversibly exchangeable between Cucumber mosaic virus (CMV) and Tomato aspermy virus (TAV). The MP of CMV is able to function with the TAV CP (chimera RT), but TAV MP is unable to promote the cell-to-cell movement in the presence of CMV CP (chimera TR). To gain fur...

The cucumovirus, cucumber mosaic virus (CMV), requires both the 3a movement protein (MP) and the capsid protein (CP) for cell-to-cell movement. Replacement of the MP of CMV with the MP of the umbravirus, groundnut rosette virus (GRV), which does not encode a CP, resulted in a hybrid virus, CMV(ORF4), which could move cell to cell in Nicotiana tabacum and long distance in N. benthamiana. After r...

The coat protein (CP) genes and flanking regions of three alstroemeriainfecting cucumber mosaic virus isolates (CMV-ALS), denoted ALS-LBO, ALS-IPO, and ALS-NAK, were cloned and their nucleotide sequence determined and compared at both nucleic acid and deduced protein level with the published sequences of CMV RNA 3. The sequences of these isolates showed more than 95% nucleotide and peptide sequ...
