Heterozygosity changes the balance between interfering and non-interfering crossovers during Arabidopsis meiosis.

Mathematical modelling, together with super-resolution imaging in Arabidopsis, demonstrates that a recently proposed coarsening model for meiotic crossover interference can explain the dynamic patterning of crossovers in many contexts, including in zyp1 and pch2 chromosome structure mutants.

A regulatory circuit that localizes to the synaptonemal complex, a liquid crystalline compartment between chromosomes, ensures crossing-over while limiting the number of crossovers between homologous chromosomes during meiosis.

Formation of a phase-separated interface between homologous chromosomes during meiosis enables regulatory signals to spread in cis over long distances, illuminating the longstanding mystery of crossover interference.

In humans, non-crossover gene conversion events transmit GC alleles in 68% of cases and exhibit a complex pattern of multiple disconnected tracts clustered within 20–30 kilobase intervals.

A computational method and genome-wide scan of low-coverage single-cell sequencing data from a large sample of human sperm suggests balanced transmission of alleles to the gamete pool.

A comprehensive and genome-wide description of the genomic make-up and frequency of meiotic recombination in Arabidopsis thaliana reveals regional preferences, including nucleosome-free regions, and two associated recombination motifs.

PLK-1/2-mediated SYP-4 phosphorylation is dependent on crossover precursor formation, triggering a switch in the dynamic state of the synaptonemal complex that reduces the formation of further double-strand breaks at late meiotic prophase.

Multi-dimensional global proteomics describes the SUMO-modified proteome during meiosis and reveals novel roles in regulating the key events of meiotic chromosome metabolism.

Investigation of meiosis in the nematode Pristionchus pacificus has illuminated evolutionary variation in this essential aspect of reproduction and established a new model for future study.
