title: Sgs1--the maestro of recombination.
abstract: The Sgs1 DNA helicase and its mammalian homolog BLM control crossover formation in mitotic cells. Zakharyevich et al. and De Muyt et al. now uncover a key role for Sgs1 in meiotic crossover regulation, which in turn reveals a joint molecule resolution pathway that produces the majority of crossovers in budding yeast.
