Meiosis drives extraordinary genome plasticity in the haploid fungal plant pathogen Mycosphaerella graminicola.

Meiosis in the haploid plant-pathogenic fungus Mycosphaerella graminicola results in eight ascospores due to a mitotic division following the two meiotic divisions.The transient diploid phase allows for recombination INTESTINEW among homologous chromosomes.However, some chromosomes of M.graminicola lack homologs and do not pair during meiosis.Becau
