Sex without crossing over in the yeast Saccharomycodes ludwigii
Genome Biology, 2021 Background Intermixing of genomes through meiotic reassortment and recombination of homologous chromosomes is a unifying theme of sexual reproduction in eukaryotic organisms and is considered crucial for their adaptive evolution.

A surge of late-occurring meiotic double-strand breaks rescues synapsis abnormalities in spermatocytes of mice with hypomorphic expression of SPO11 [PDF]
, 2015 Meiosis is the biological process that, after a cycle of DNA replication, halves the cellular chromosome complement, leading to the formation of haploid gametes.

PLoS Genetics, 2022 During meiosis, recombination between homologous chromosomes (homologs) generates crossovers that promote proper segregation at the first meiotic division. Recombination is initiated by Spo11-catalyzed DNA double strand breaks (DSBs). 5' end resection of

Meiotic recombination in Caenorhabditis elegans [PDF]
Chromosome Research, 2007 The faithful segregation of homologous chromosomes during meiosis is dependent on the formation of physical connections (chiasma) that form following reciprocal exchange of DNA molecules during meiotic recombination. Here we review the current knowledge in the Caenorhabditis elegans meiotic recombination field.

A simple model for the influence of meiotic conversion tracts on GC content. [PDF]
PLoS ONE, 2011 A strong correlation between GC content and recombination rate is observed in many eukaryotes, which is thought to be due to conversion events linked to the repair of meiotic double-strand breaks. In several organisms, the length of conversion tracts has

H4K44 Acetylation Facilitates Chromatin Accessibility during Meiosis
Cell Reports, 2015 Meiotic recombination hotspots are associated with histone post-translational modifications and open chromatin. However, it remains unclear how histone modifications and chromatin structure regulate meiotic recombination. Here, we identify acetylation of
