Identification of dna components required for induction of cotton leaf curl disease.
A single-stranded DNA molecule approximately 1350 nucleotides in length is identified which, when coinoculated with the begomovirus to cotton, induces symptoms typical of CLCuD, including vein swelling, vein darkening, leaf curling, and enations. Expand

It is demonstrated that yellow vein disease of A. conyzoides results from co-infection by AYVV DNA A and a circular DNA that is approximately half its size that is designated DNA beta, which represents a satellite-like DNA. Expand
Characterisation of Sri Lankan cassava mosaic virus and Indian cassava mosaic virus: evidence for acquisition of a DNA B component by a monopartite begomovirus.
SLCMV DNA A has biological characteristics of a monopartite begomovirus, and the virus probably evolved by acquisition of a DNA B component from ICMV, which was transmitted with low efficiency from cassava to Nicotiana benthamiana. Expand

A short review on each virus of the Top 10 list and its importance is presented, with the intent of initiating discussion and debate amongst the plant virology community, as well as laying down a benchmark, as it will be interesting to see in future years how perceptions change and which viruses enter and leave the Top10.

Induction of plant cell division by beet curly top virus gene C4
In situ hybridization is used to show that BCTV infection is closely associated with the vascular system in these hosts, although hyperplastic cells associated with wild-type virus infection frequently do not contain detectable levels of viral DNA. Expand
A nanovirus-like DNA component associated with yellow vein disease of Ageratum conyzoides: evidence for interfamilial recombination between plant DNA viruses.
The results provide direct evidence for recombination between distinct families of plant single-stranded DNA viruses and suggest that coinfection by geminivirus and nanovirus-like pathogens may be a widespread phenomenon. Expand
The DNA β satellite component associated with ageratum yellow vein disease encodes an essential pathogenicity protein (βC1)
It is demonstrated that the satellite encodes at least one protein that plays a major role in symptom development and is essential for disease progression in ageratum, the natural host of the AYVD complex. Expand
DNA forms of the geminivirus African cassava mosaic virus consistent with a rolling circle mechanism of replication.
DNA from African cassava mosaic virus (ACMV)-infected Nicotiana benthamiana is analysed by two-dimensional agarose gel electrophoresis and detected ACMV-specific DNAs by blot-hybridisation, suggesting a rolling circle mechanism of DNA replication. Expand
Bean yellow dwarf virus RepA, but not rep, binds to maize retinoblastoma protein, and the virus tolerates mutations in the consensus binding motif.
It is demonstrated that whereas RepA binds to Rb protein, Rep does not, suggesting that RepA alone regulates host gene expression and progression of cells to S-phase. Expand
Geminivirus pathogenicity protein C4 interacts with Arabidopsis thaliana shaggy-related protein kinase AtSKeta, a component of the brassinosteroid signalling pathway.
The interaction with AtSKeta indicates that BCTV C4 interacts with the brassinosteroid signalling pathway and is required to produce the wild-type disease phenotype. Expand
