Title: Genome replication/expression strategies of positive-strand RNA viruses: A simple version of a combinatorial classification and prediction of new strategies Cord-id: 4mrh7qjs Document date: 1991_1_1
ID: 4mrh7qjs
Snippet: A combinatorial approach to the classification of replication/expression strategies of positive-strand RNA virus genomes is suggested. Eighteen genome strategies defined as combinations of distinct modes of expression and replication are briefly characterized, 10 of which have been actually found in diverse virus groups. The chances for realization of the remaining eight strategies are evaluated. It is demonstrated that positive-strand RNA virus genome strategies are not necessarily monophyletic
Document: A combinatorial approach to the classification of replication/expression strategies of positive-strand RNA virus genomes is suggested. Eighteen genome strategies defined as combinations of distinct modes of expression and replication are briefly characterized, 10 of which have been actually found in diverse virus groups. The chances for realization of the remaining eight strategies are evaluated. It is demonstrated that positive-strand RNA virus genome strategies are not necessarily monophyletic characters and could, in some cases, evolve convergently.
