Evolution of RNA Viruses

Annual Review of Microbiology, 1988
The evolution of RNA viruses has received a great deal of attention in the past several years. The subject is based on information very different from that considered: in other evolutionary discussions. As obligate intracellular parasites, viruses leave no fossil record; indeed the oldest historical accounts describing symptoms believed to be caused by

Transfer RNA in RNA Tumor Viruses

1977
Publisher Summary This chapter reviews that the presence of the majority of the tRNAs inside an RNA tumor virus remains an enigma. The finding that specific tRNA molecules can serve as primers for DNA synthesis is of fundamental importance in the field of molecular biology.

EVOLUTION OF RNA VIRUSES

Annals of the New York Academy of Sciences, 1980
These arguments lead to the suggestion that four independent evolutionary lines exist within the general group of RNA viruses. These are positive strand viruses, negative strand viruses, double stranded viruses, and retroviruses. Three of the viral systems may well have shared genes but the double-stranded RNA viruses appear to represent a very ...

RNA-Dependent RNA Polymerases, Viruses, and RNA Silencing

Science, 2002
Most viruses have RNA genomes that are replicated and transcribed into messenger RNA by viral RNA–dependent RNA polymerases (RdRps), usually in concert with other viral and host factors. Many, if not most, eukaryotes also encode putative RdRps that have been implicated in sequence-specific, RNA-triggered gene silencing.

(1971) There is firm genetic evidence that sarcoma viruses carry an“oncogene’, that is, a specific gene for neoplastic transformation, which we may call src, for sarcoma function.

RNA-based viruses

1992
Abstract This chapter describes the use of protoplasts to study various aspects of the replication cycle of ( +) strand RNA viruses that infect plants. The genetic analysis of these viruses, which comprise the overwhelming majority of plant viruses, has been accelerated in recent years by the development of methods that produce ...
