Meiosis is a highly conserved eukaryotic cell division that produces gametes required for sexual reproduction. During meiosis, homologous chromosomes undergo recombination, which can result in reciprocal crossover and gene conversion. Meiosis and recombination have a profound effect on natural genetic variation and genome evolution, which in turn has strategic importance for crop breeding. I will present our work using genome-wide methods to map meiotic recombination, primarily in the model plant Arabidopsis thaliana.
