Study Notes
- The honey mushroom in Oregon is a huge subterranean mycelium that covers 890 hectares and has been growing for 2,600 years.
- Fungi play an important role in ecosystems by decomposing dead organisms and recycling vital chemical elements back to the environment.
- Fungi are heterotrophs that acquire their nutrients by absorption through exoenzymes.
- Fungi reproduce by producing vast numbers of spores either sexually or asexually.
- Fungi descended from an aquatic, single-celled, flagellated protist, and have radiated into a diverse set of lineages.
- Chytrids, zygomycetes, microsporidia, and ascomycetes are all different groups of fungi with unique characteristics.
- Glomeromycetes form symbiotic mycorrhizae with plant roots.
- Ascomycetes, or sac fungi, produce sexual spores in saclike asci and are called sac fungi.
- Fungi have been cultivated by humans for centuries for food, antibiotics, bread, beer, and wine.
- Fungi cause 80% of plant diseases.- Fungi reproduce through spores that are dispersed by wind.
- Ascomycetes have a heterokaryotic stage during the formation of ascocarps.
- Basidiomycetes are best at decomposing lignin in wood and produce basidiospores.
- Fungi are important decomposers and symbionts in ecosystems.
- Mycorrhizae are important for plant growth and almost all vascular plants rely on them.
- Lichens are a symbiotic association of photosynthetic microorganisms and fungal hyphae.
- Lichens are pioneers on newly cleared rock and soil surfaces and are sensitive to air pollution.
- Fungi can also be pathogens.
- Neurospora crassa is a well-studied ascomycete and serves as a model organism.
- Some species of ants and termites raise fungi in "farms" and feed them leaves.
