Pseudorecombination between infectious cloned DNA components of tomato mottle and bean dwarf mosaic geminiviruses

Pseudorecombination and complementation between potato yellow mosaic geminivirus and tomato golden mosaic geminivirus.

Pseudorecombinants made by exchanging the cloned, infectious genome components (DNAs A and B) of potato yellow mosaic geminivirus (PYMV) and the common strain (cs) of tomato golden mosaic geminivirus (csTGMV) are not infectious in their common host Nicotiana benthamiana. In an N. benthamiana leaf disc assay neither PYMV DNA A nor TGMV DNA A transreplicated each other's DNA B component. The abil...

Nucleotide sequence of the infectious cloned DNA components of African cassava mosaic virus (Nigerian strain)

Complete Genome Sequence of a Tomato-Infecting Tomato Mottle Mosaic Virus in New York.

The complete genome sequence of an isolate of tomato mottle mosaic virus (ToMMV) infecting tomatoes in New York was obtained using small RNA (sRNA) deep sequencing. ToMMV_NY-13 shared 99% sequence identity with isolates from Mexico and Florida. Broader distribution of this emerging virus is a cause for concern to the tomato industry.

Nucleotide sequence of bean golden mosaic virus and a model for gene regulation in geminiviruses.

We have sequenced the genome of bean golden mosaic virus, which comprises two circular single-stranded DNA molecules (2646 and 2587 nucleotides long) of mostly unique sequence. Comparison of the sequences of bean golden mosaic virus and of cassava latent virus, which share serological relationship but are very different in host range and geographical origin, shows that each virus has a unique 2...

Bean Dwarf Mosaic Geminivirus Movement Proteins Recognize DNA in a Form- and Size-Specific Manner

Plant viral movement proteins mediate the cell-to-cell movement of nucleic acids. This involves either a direct interaction between the viral movement protein and the nucleic acid or an indirect interaction involving host factors. The bipartite geminiviruses possess two movement proteins, BV1 and BC1, that coordinate movement of viral DNA across nuclear and plasmodesmal boundaries, respectively...
