Study Notes
Fungal Classifications Overview
- "Mycota" designates a phylum in the fungal classification.
- Phylum Chytridiomycota includes the only class, the Chytridiomycetes.
- Chytrids are primitive Eumycota, primarily aquatic, and have flagellated gametes.
- Zygomycota, known as Conjugated Fungi, produce non-septated hyphae and include bread mold Rhizopus stolonifer.
- Zygomycetes contribute to commercial applications, producing intermediates for semi-synthetic steroid hormones.
- Conjugation in fungi, which differs from bacterial conjugation, leads to the term "conjugated fungi."
- Ascomycota, or Sac Fungi, reproduce within sac-like structures called asci.
- Aflatoxins are toxic compounds released by fungi from the genus Aspergillus.
- Cryptococcus neoformans can cause severe respiratory illnesses.
Key Characteristics of Fungal Phyla
- Chytridiomycota (chytrids) are the most primitive fungi; they reproduce sexually and asexually via zoospores.
- Zygomycota undergo fusion of hyphae to produce zygospores in zygosporangia during sexual reproduction.
- Ascomycota predominantly reproduce asexually but form ascospores in asci during sexual reproduction.
- Basidiomycota, known as club fungi, produce fruiting bodies containing basidia.
- Deuteromycota, previously classified fungi with no known sexual cycle, are now included in Ascomycota and Basidiomycota.
- Glomeromycota form symbiotic mycorrhizal associations with plant roots.
Important Concepts
- A dikaryotic ascus in the ascocarp undergoes karyogamy, meiosis, and mitosis to produce eight ascospores.
- A basidiocarp serves as the fruiting body for mushroom-producing fungi.
- Chytridiomycota is identified as the most primitive phylum of fungi.
- Basidiomycota includes fungi that produce club-shaped structures with spores.
- Glomeromycota establish beneficial symbiotic relationships with tree roots.
- Fungi with no sexual reproduction were once classified as Deuteromycota.
- Animals help in dispersing fungal spores by ingesting and excreting them.
