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 stage in a basidiomycete's life cycle where the cytoplasm of two haploid hyphae fuse, creating a dikaryotic mycelium with two haploid nuclei in each cell. This occurs before karyogamy (fusion of nuclei) and meiosis (formation of haploid spores). If an enzyme prevented the fusion of hyphae, plasmogamy would not occur, and the basidiomycete would not be able to enter the next stage of the life cycle, halting reproduction.
