COmapper uses long-read sequencing to map meiotic crossovers in Arabidopsis with high resolution, showing comparable accuracy to short-read methods and revealing crossover enrichment at gene promoters.

The paper investigates how REC8-cohesin interacts with chromatin and transcription to regulate meiotic recombination in Arabidopsis.

The paper maps meiotic crossovers in Arabidopsis thaliana disease resistance genes, finding that interhomolog divergence suppresses crossover frequency and that local context influences recombination outcomes in mutants.

The paper maps meiotic DSBs in Arabidopsis using SPO11-1-oligonucleotides and shows their association with chromatin features and transposon activity.

This study shows that disrupting H3K9me2 and non-CG DNA methylation in Arabidopsis increases meiotic DSBs in centromeres and crossovers in pericentromeric heterochromatin.
