Most models of homologous recombination invoke cleavage of Holliday junctions to explain crossing over. The Mus81·Eme1 endonuclease from fission yeast and humans cleaves Holliday junctions and other branched DNA structures, leaving its physiological substrate uncertain. We report here thatSchizosaccharomyces pombe mus81mutants have normal or elevated frequencies of gene conversion but 20- to 100-fold reduced frequencies of crossing over. Thus, gene conversion and crossing over can be genetically separated, and Mus81 is required for crossing over, supporting the hypothesis that the fission yeast Mus81·Eme1 protein complex resolves Holliday junctions in meiotic cells.
