![**Question:**
An enzyme that prevents the fusion of hyphae is introduced to a basidiomycete. Which stage of the reproductive cycle would be halted as a result?
- Plasmogamy
- Fertilization
- Karyogamy
- Germination
**Explanation:**
This question pertains to the reproductive cycle of basidiomycetes, which are a class of fungi. The stages mentioned have specific roles in the sexual reproduction of fungi:
- **Plasmogamy**: This is the stage where the fusion of the cytoplasm of two parent mycelia occurs. If an enzyme prevents the fusion of hyphae, plasmogamy would be halted, as it requires the merging of two hyphal cells.
- **Fertilization**: Typically refers to the fusion of gametes in plants and animals but in fungi may not specifically describe a separate stage distinct from plasmogamy or karyogamy.
- **Karyogamy**: This stage involves the fusion of two nuclei. It usually occurs after plasmogamy.
- **Germination**: This is the process whereby spores develop into new mycelium. It occurs after meiosis and spore formation, not directly related to hyphal fusion.
In the context of this question, the correct answer would be **plasmogamy**, as it directly involves the fusion of hyphae.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Febe7c92b-0501-4d21-bc58-0a2199f89a0a%2Feed4a5d6-5a70-454a-b0d0-cc7e996e004e%2Fyb5qn5k_processed.jpeg&w=3840&q=75)
