The raison d'être of meiosis is shuffling of genetic information via Mendelian segregation
and, within individual chromosomes, by DNA crossing-over. These outcomes are enabled …

Meiosis halves diploid chromosome numbers to haploid levels that are essential for sexual
reproduction in most eukaryotes. Meiotic recombination ensures the formation of bivalents …

Meiotic recombination initiates from DNA double-strand breaks (DSBs) generated by SPO11
topoisomerase-like complexes. Meiotic DSB frequency varies extensively along eukaryotic …

The genomic revolution of the past decade has greatly improved our understanding of the
genetic make-up of living organisms. The sequencing of crop genomes has completely …

Understanding the distribution of crossovers along chromosomes is crucial to evolutionary
genomics because the crossover rate determines how strongly a genome region is …

Crossovers (COs), that drive genetic exchange between homologous chromosomes, are
strongly biased toward subtelomeric regions in plant species. Manipulating the rate and …

During meiosis, homologous chromosomes undergo reciprocal crossovers, which generate
genetic diversity and underpin classical crop improvement. Meiotic recombination initiates …

Genome duplication, which results in polyploidy, is disruptive to fundamental biological
processes. Genome duplications occur spontaneously in a range of taxa and problems such …

Meiosis presents many important mysteries that await elucidation. Here we discuss two such
aspects. First, we consider how the current meiotic program might have evolved. We …

Whole genome duplication is a prominent feature of many highly evolved organisms,
especially plants. When duplications occur within species, they yield genomes comprising …
