Allelic and ectopic recombination between Ty elements in yeast.
Allelic and nonallelic (ectopic) recombination events were analyzed in a set of isogenic strains that carry marked Ty elements. We found that allelic recombination between Ty elements occurred at normal frequencies both in meiosis and mitosis. The marked Ty elements were involved in a large variety of different types of ectopic recombination and this variety was greater in mitosis than in meios...
متن کاملAllelic and ectopic interactions in recombination-defective yeast strains.
Ectopic recombination in the yeast Saccharomyces cerevisiae has been investigated by examining the effects of mutations known to alter allelic recombination frequencies. A haploid yeast strain disomic for chromosome III was constructed in which allelic recombination can be monitored using leu2 heteroalleles on chromosome III and ectopic recombination can be monitored using ura3 heteroalleles on...
متن کاملTranscriptional induction of Ty recombination in yeast.
Families of repeated sequences are present in the genomes of all eukaryotes. Little is known about the mechanism(s) that prevents recombination between repeated sequences. In the yeast Saccharomyces cerevisiae, recombination between homologous sequences placed at nonhomologous locations in the genome (ectopic recombination) has been shown to occur at high frequencies for artificially created re...
متن کاملTransposon tagging using Ty elements in yeast.
We have used the ability to induce high levels of Ty transposition to develop a method for transposon mutagenesis in Saccharomyces cerevisiae. To facilitate genetic and molecular analysis, we have constructed GAL1-promoted TyH3 or Ty917 elements that contain unique cloning sites, and marked these elements with selectable genes. These genes include the yeast HIS3 gene, and the plasmid PiAN7 cont...
متن کاملTy Elements of the Yeast Saccharomyces Cerevisiae
Transposable elements in the yeast Saccharomyces cerevisiae are a heterogeneous group of mobile genetic elements. Ty elements transpose via an intermediate RNA-molecule using the same replication and integration mechanisms as the metazoan retroviruses. Ty1 is a retrotransposons with life cycle very similar to that of oncogenes. This similarity provides an attractive model for virus-host interac...
