What are the characteristics of Basidiomycetes?
Salient features
- Basidiomycetes are characterized primarily by producing their sexual spores, termed basidiospores (typically 4 in number), on the outside of a specialized, microscopic, spore producing structure called the basidium.
- Basidiospores are haploid but can be either uninucleate or multinucleate upon maturity.
What are Basidiomycota known for?
The fungal group basidiomycota is best known for the production of large fruitbodies such as the mushrooms, puffballs, brackets, etc. However, the group also contains some microscopic fungi, including the important rust fungi and smut fungi that parasitise plants (see Biotrophic parasites), and some yeasts.
What are characteristics of ascomycota?
The majority of known fungi belong to the Phylum Ascomycota, which is characterized by the formation of an ascus (plural, asci), a sac-like structure that contains haploid ascospores. Filamentous ascomycetes produce hyphae divided by perforated septa, allowing streaming of cytoplasm from one cell to another.
What makes basidiomycota unique?
One of the most fascinating characteristics of Basidiomycota is the production of forcibly discharged ballistospores (Fig. 2), which are propelled into the air from the sterigma. Ballistospores may be sexual or asexual, and may be produced by basidia, hyphae, yeast cells, or even other ballistospores.
What are the characteristics of Glomeromycota?
Characteristics
- obligate symbionts.
- formation of arbuscules in plant roots.
- large, multinucleate spores with layered walls.
- non-septate hyphae.
How do humans use Basidiomycota?
While mushrooms are used for food, there are also many other uses humans have for Basidiomycota. For example, the toxin phalloidin, found in the mushroom Amanita phalloides, is incorporated into flourescent stains that are used by cell biologists to view the cytoskeleton.
How do you identify Basidiomycota?
A feature used to identify Basidiomycota, aside from the presence of basidia, is the degree of separation between individual cells. Basidiomycota have more septate hyphae than Zygomycota, though their septae are perforated, allowing cytoplasm to flow freely between cells.
What is an example of Zygomycota?
Mucorales
MucoromycotinaZoopagomycotina
Zygomycota/Lower classifications
A common example of a zygomycete is black bread mold (Rhizopus stolonifer), a member of the Mucorales. It spreads over the surface of bread and other food sources, sending hyphae inward to absorb nutrients.
What causes Basidiomycota?
Many Basidiomycota produce basidia on multicellular fruiting bodies (e.g., mushrooms), but basidia can also be formed directly from yeasts or other single cells.
What are some examples of Glomeromycota?
Examples of Glomeromycota
- Gigaspora margarita: Fungus that lives on plant roots without destroying the plant.
- Geosiphon pyriformis: Lives on cyanobacteria rather than plants.
- Scutellospora persica: Another root-dwelling fungus.
- Acaulospora scrobiculata: Often found in the roots of soybean plants.
