Definition
- Noun:
- A taxonomic subdivision of fungi: Zygomycotina refers to a major division or phylum within the kingdom Fungi. The defining characteristic of this group is the formation of a thick-walled resting spore called a zygospore, which results from the sexual fusion of two similar gametangia.
Usage Examples
- Noun:
- The Zygomycotina include common molds like Rhizopus.
- Scientists study the life cycle of Zygomycotina to understand fungal reproduction.
Advanced Usage
- In taxonomic classification: The term is used in formal scientific contexts to categorize a specific lineage of fungi. It is often discussed in relation to other fungal divisions like Ascomycota and Basidiomycota.
- The phylogenetic position of Zygomycotina has been revised with modern DNA analysis.
Variants and Related Words
- Zygomycota (n): This is a synonym and the more commonly used modern term for the same taxonomic group.
- The phylum Zygomycota is characterized by coenocytic hyphae.
- Zygomycete (n): A member of the Zygomycotina/Zygomycota.
- Bread mold is a well-known zygomycete.
- Zygospore (n): The diploid resting spore characteristic of this group, formed by sexual reproduction.
- The zygospore can remain dormant until conditions are favorable for germination.
Synonyms
- Zygomycota: The synonymous phylum name.
- Conjugation fungi: An informal descriptive name referencing the sexual fusion process.
Related Terms and Concepts
- Gametangia (n): The specialized structures that fuse to form the zygospore.
- Coenocytic (adj): Having multiple nuclei within a single, continuous cell membrane, a feature of hyphae in this group.
- Saprobes (n): Organisms that feed on dead organic matter; many Zygomycotina are saprobic.
Noun
