Multitasking in Replication Is Common among Geminiviruses

★ ★ ★ ☆ ☆

The results extend our knowledge about multitasking in the replication of geminiviruses in several aspects. First, multitasking is not a peculiarity of AbMV, e.g., as a consequence of a special adaptation to the vegetatively propagated host but a widespread phenomenon among geminiviruses that infect dicots. ... In the present study, samples ...

replication, and the mechanism whereby AL3 acts as a geminivirus replication accessory factor is unknown. In spite of the strong functional conservation between the trans-acting replication factors encoded by bipartite genome geminiviruses, these proteins can show specificity for repli- cation of their cognate genomes.

Replication of the single-stranded DNA genome of plant geminiviruses follows a rollin circle mechanism. It strictly depends on a ‘replication initiator protein’ (Rep) which is the sole viral protein essential for replication. Rep protein catalyzes multiple reactions duringthe reproductive cycle of the virus.

geminiviruses, which have no double-stranded RNA phase in their replication cycle, can induce and suppress the PTGS and become targets for PTGS. Here, we summarize recent developments in determining how these viruses trigger PTGS and how they suppress the induced PTGS, as well as how we can use the system to

10/31/2008 · As the nucleotide sequence of the SL is also highly conserved and particularly among begomoviruses, we hypothesised that a binary vector containing only the SL could be used for isolating, genotyping and phenotyping genetic variants of geminiviruses for intra-population studies and experimental evolution.

3/1/2000 · Plant cell growth and development depend on continuous cell proliferation which is restricted to small regions of the plant called meristems. Infection by geminiviruses, small DNA viruses whose replicative cycle relies on host cell factors, is excluded from those proliferating areas. Since most of the replicative factors are present, almost exclusively, in proliferating cells, geminivirus ...

Geminiviruses also control the host plant's cell cycle, allowing cells in which the virus has used up its DNA replicating capabilities to regain the ability to support high levels of (viral) DNA replication.

Geminiviruses do not encode DNA or RNA polymerases and so depend on cellular replication and transcription machinery to express their genes and amplify their gen-omes (Hanley-Bowdoin et al. 1999). Consequently, they are good models for the study of host replication, tran-scription, and how these processes can be affected by epigenetic ...

7/2/2008 · We propose that plants use chromatin methylation as a defense against DNA viruses, which geminiviruses counter by inhibiting global methylation. In addition, our results establish that geminiviruses can be useful models for genome methylation in plants and suggest that there are redundant pathways leading to cytosine methylation.
