By Which characteristics separate the Basidiomycetes from the other fungi?
As a group, the basidiomycota have some highly characteristic features, which separate them from other fungi. They are the most evolutionarily advanced fungi, and even their hyphae have a dinstinctly “cellular” composition. This point is best illustrated by the life cycle below.
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.
Are basidiospores asexual?
Are Basidiospores asexual? No. The life cycle of Basidiomycota can be divided into two phases – sexual and asexual. Basidiospores are used in sexual reproduction.
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 Ascomycetes?
Ascomycetes
- One character that is present is most of the ascomycetes is a reproductive structure known as ascus or asci.
- Mostly they are terrestrial, parasitic or coprophilous.
- They are unicellular or multicellular fungi.
- The mycelium is made up of septate and branched hyphae.
- The cell wall is made up of chitin or ꞵ-glucans.
What is the common name for Basidiomycota?
Classification of Fungi
| Group | Common Name | Example |
|---|---|---|
| Zygomycota | Bread molds | Rhizopus stolonifer |
| Ascomycota | Sac fungi | Saccharomyces cerevisiae Aspergillus Penicillium |
| Basidiomycota | Club fungi | Mushrooms |
| Glomeromycota | Mycorrhizae | Acaulospora |
What do basidiospores infect?
The basidiospores are wind-borne to the alternate host, species of susceptible Berberis and Mahonia, but seldom cause infection more than 180 to 270 m from the source. Most of the infections occur on the upper leaf surface, although infections on the berries, stems, and other plant surfaces do occur.
What will basidiospores give rise to?
zygote
The sexual spores form in the club-shaped basidium and are called basidiospores. In the basidium, nuclei of two different mating strains fuse (karyogamy), giving rise to a diploid zygote that then undergoes meiosis.
Are yeasts ascomycetes?
Ascomycota. All members of Class Ascomycota that reproduce sexually produce an ascus (from the Greek “askos,” meaning sac), containing spores. Class Saccharomycotina are yeasts; round, unicellular fungi that reproduce by budding.
