Abstract:
:Viruses are found in almost all organisms and physical habitats. One interesting example is the yeast viral 'killer system'. The virus provides the host with a toxin directed against strains that do not carry it, while the yeast cell enables its propagation. Although yeast viruses are believed to be common, they have been actually described only for a limited number of yeast isolates. We surveyed 136 Saccharomyces cerevisiae and S. paradoxus strains of known origin and phylogenetic relatedness. Of these, 14 (c. 10%) were infected by killer viruses of one of the three types: K1, K2 or K28. As many as 34 strains (c. 25%) were not sensitive to at least one type of the killer toxin. In most cases, resistance did not disappear after attempts to cure the host strains from their viruses, suggesting that it was encoded in the host's genome. In terms of phylogeny, killer strains appear to be more related to each other than to nonkiller ones. No such tendency is observed for the phenotype of toxin resistance. Our results suggest that even if the killer toxins are not always present, they do play significant role in yeast ecology and evolution.
