    The reproductive genes of fungi, like those of many other organisms, are thought to diversify rapidly. This phenomenon could be associated with the formation of reproductive barriers and speciation. Ascomycetes produce ...
  • Ceratocystidaceae exhibit high levels of recombination at the mating-type (MAT) locus 
    Simpson, M.C. (Melissa Claire); Coetzee, Martin Petrus Albertus; Van der Nest, Magrieta Aletta; Wingfield, Michael J.; Wingfield, Brenda D. (Elsevier, 2018-12)
    Mating is central to many fungal life cycles and is controlled by genes at the mating-type (MAT) locus. These genes determine whether the fungus will be self-sterile (heterothallic) or self-fertile (homothallic). Species ...
