Mitotic recombination in yeast: what we know and what we don't know.

Journal Article (Review;Journal Article)

Saccharomyces cerevisiae is at the forefront of defining the major recombination mechanisms/models that repair targeted double-strand breaks during mitosis. Each of these models predicts specific molecular intermediates as well as genetic outcomes. Recent use of single-nucleotide polymorphisms to track the exchange of sequences in recombination products has provided an unprecedented level of detail about the corresponding intermediates and the extents to which different mechanisms are utilized. This approach also has revealed complexities that are not predicted by canonical models, suggesting that modifications to these models are needed. Current data are consistent with the initiation of most inter-homolog spontaneous mitotic recombination events by a double-strand break. In addition, the sister chromatid is preferred over the homolog as a repair template.
