With the development of new sequencing technologies in the past decade, yeast genomes have been extensively sequenced and their structures investigated. Transposable elements (TEs) are ubiquitous in eukaryotes and constitute a limited part of yeast genomes. However, due to their ability to move in genomes and generate dispersed repeated sequences, they contribute to modeling yeast genomes and thereby induce plasticity. This review assesses the TE contents of yeast genomes investigated so far. Their diversity and abundance at the inter- and intraspecific levels are presented, and their effects on gene expression and genome stability is considered. Recent results concerning TE–host interactions are also analyzed.
