At which stage of a basidiomycete's life cycle would reproduction be halted if an enzyme that prevented the fusion of hyphae was introduced?

Question

Quizplus · Accepted Answer

Plasmogamy is the fusion of cytoplasm from two different mating types, and is the stage where the hyphae fuse together to form a dikaryotic mycelium. If an enzyme prevented the fusion of hyphae, plasmogamy would be halted and the dikaryotic mycelium would not form, ultimately preventing reproduction. Fertilization and karyogamy occur after plasmogamy, and germination occurs before plasmogamy.
