Fig. 2. (A) Limitation of crossover number in the Arabidopsis genome. During Arabidopsis male meiosis, an average of 250 meiotic DSBs and 11 crossovers occur throughout the genome. (B) A strategy for plant breeding programs to increase crossovers in both euchromatin and heterochromatin of hybrid lines by genetic and epigenetic disruptions. Enhancing the number of crossovers in the genome helps accelerate genetic mapping of desirable traits and generation of new varieties.
