Stop making sense or Regulation at the level of termination in eukaryotic protein synthesis

AbstractAn increasing number of examples of translational regulation at the level of termination has been recently reported in eukaryotes. This paper reviews our present knowledge on this topic and proposes an understanding of these regulations by relating the study of viral gene expression to a comprehensive view of the mechanisms and components of the translational process

Can Plant RNA Viruses Exchange Genetic Material?

The problem of the exchange of genetic material among viruses is intimately related to that of the evolution of these viruses, as are also the acquisition or the loss of genetic material. Similarly, the concept of virus evolution is associated with that of the origin of viruses

Plant viruses and new perspectives in cross-protection

Cross-protection in plants is the phenomenon whereby a plant preinoculated with a mild virus strain becomes resistant to subsequent inoculation by a related severe strain. It has been used on a large scale in cases where no resistant plants are available. Although several hypotheses have been proposed to explain the molecular mechanism underlying cross-protection, no single hypothesis can account for all the data obtained. Recently, a phenomenon akin to cross-protection has been achieved in transformed plants harboring the cDNA of a part of a viral RNA genome. These results obtained by genetic engineering raise new hopes for obtaining plants resistant to virus infection
