Examples of ascomycete in the following topics:

  • Ascomycota: The Sac Fungi

    • Many ascomycetes are of commercial importance.
    • Other ascomycetes parasitize plants and animals, including humans.
    • Ascomycetes not only infest and destroy crops directly, they also produce poisonous secondary metabolites that make crops unfit for consumption.
    • Filamentous ascomycetes produce hyphae divided by perforated septa, allowing streaming of cytoplasm from one cell to the other.
    • The lifecycle of an ascomycete is characterized by the production of asci during the sexual phase.
  • Deuteromycota: The Imperfect Fungi

    • Molecular analysis shows that the closest group to the deuteromycetes is the ascomycetes.
    • In fact, some species, such as Aspergillus, which were once classified as imperfect fungi, are now classified as ascomycetes.
  • Plant Pathogens

    • The majority of phytopathogenic fungi belong to the Ascomycetes and the Basidiomycetes .
  • Whole-Genome Duplication

    • Based on these observations, they determined that Saccharomyces cerevisiae underwent a whole-genome duplication soon after its evolutionary split from Kluyveromyces, a genus of ascomycetous yeasts.
  • Fungi as Plant, Animal, and Human Pathogens

    • (a) Ringworm presents as a red ring on skin; (b) Trichophyton violaceum, shown in this bright field light micrograph, causes superficial mycoses on the scalp; (c) Histoplasma capsulatum is an ascomycete that infects airways and causes symptoms similar to influenza.
  • Importance of Fungi in Human Life

    • The morel mushroom is an ascomycete much appreciated for its delicate taste.
