Holliday junctions maintain chromosome synapsis to enable crossover assurance in budding yeast.

Holliday junctions maintain chromosome synapsis to enable crossover assurance in budding yeast.

A groundbreaking study published in Nature unveils the intricate molecular mechanisms by which cells regulate the formation of DNA double-strand breaks (DSBs) during meiosis to ensure proper chromosome synapsis and crossover formation. This process is fundamental for genetic diversity and accurate chromosome segregation in sexually reproducing organisms, such as budding yeast and mice. Meiotic recombination is initiated by the programmed induction of DSBs, which facilitate the pairing and synapsis of homologous chromosomes via the synaptonemal complex (SC).

Saccharomyces cerevisiae strains used in this study were SK1 derivatives, as described in Supplementary Table 1. The following alleles have been previously described: ndt80Δ62, YEN1ON (ref. 34), YEN1ON-ND (ref. 35), P GAL1 -YEN1ON-3FLAG-2TEV-10HIS35, P GPD1 -GAL4(848).ER63, HIS4::LEU2 alleles for physical...
