Meiotic recombination and chromosomes reorganization are strictly interconnected programs and our studies aim to elucidate the molecular basis of chromosomes behavior during pairing and recombination. We use a combined cytological, and molecular genetic approach in the filamentous fungus Sordaria macrospora, a particularly suited model to study early stages of meiotic prophase. In collaboration with Prof. Zickler and Prof. Kleckner we have characterized a number of proteins involved in recombination and cohesion, analyzing their roles in the meiotic nuclear reorganization by both deletions or specific mutations and localizing them using tagged fluorescent proteins. We showed that programmed DSBs are required for chromosomes pairing and SCs formation, and that even exogenous provided DSBs are sufficient to drive correct progression of meiotic prophase.
 We are now investigating how proteins involved in later steps of recombination contribute to chromosome alignment during meiotic prophase.
