Meiosis drives extraordinary genome plasticity in the haploid fungal plant pathogen Mycosphaerella graminicola Jun 2009 | Wittenberg A H, van der Lee T A, Ben M'barek S, Ware S B, Goodwin S B, Kilian A, Visser R G, Kema G H, Schouten H J, PLOS ONE. 10 June 2009. Volume 4(6) : e5863. DOI: 10.1371/journal.pone.0005863 | Show abstract ... 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 among homologous chromosomes. View paper (you will be redirected to another page)
