plasmogamy
Quick Summary
Plasmogamy is a crucial stage in the sexual reproduction of fungi. It is the fusion of the cellular contents of two parent cells, but importantly, the nuclei do not fuse at this point. This process results in a dikaryotic state, where each cell contains two distinct haploid nuclei, one from each parent.123
This dikaryotic stage can be prolonged and is a prominent phase in the life cycle of many fungi. Following plasmogamy, the next step in sexual reproduction is karyogamy, the fusion of these two haploid nuclei to form a diploid nucleus, which then develops into a zygote. This is a fundamental part of how fungi achieve genetic diversity and adapt to different environments.32
