Ty 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...
متن کاملMitotic and meiotic gene conversion of Ty elements and other insertions in Saccharomyces cerevisiae.
We examined meiotic and mitotic gene conversion events involved in deletion of Ty elements and other insertions from the genome of the yeast Saccharomyces cerevisiae. We found that Ty elements and one other insertion were deleted by mitotic gene conversion less frequently than point mutations at the same loci. One non-Ty insertion similar in size to Ty, however, did not show this bias. Mitotic ...
متن کاملTempo and mode of Ty element evolution in Saccharomyces cerevisiae.
The Saccharomyces cerevisiae genome contains five families of long terminal repeat (LTR) retrotransposons, Ty1-Ty5. The sequencing of the S. cerevisiae genome provides an unprecedented opportunity to examine the patterns of molecular variation existing among the entire genomic complement of Ty retrotransposons. We report the results of an analysis of the nucleotide and amino acid sequence varia...
متن کاملFitness effects of Ty transposition in Saccharomyces cerevisiae.
It has been suggested that the primary evolutionary role of transposable elements is negative and parasitic. Alternatively, the target specificity and gene regulatory capabilities of many transposable elements raise the possibility that transposable element-induced mutations are more likely to be adaptively favorable than other types of mutations. Populations of Saccharomyces cerevisiae contain...
متن کاملMeiotic recombination between duplicated genetic elements in Saccharomyces cerevisiae.
We have studied the meiotic recombination behavior of strains carrying two types of duplications of an 18.6-kilobase HIS4 Bam HI fragment. The first type is a direct duplication of the HIS4 Bam HI fragment in which the repeated sequences are separated by Escherichia coli plasmid sequences. The second type, a tandem duplication, has no sequences intervening between the repeated yeast DNA. The HI...
