We focused on several key events during fertilization from membrane fusion to karyogamy of sperm cells and egg cells. 探讨了从精细胞和卵细胞质膜融合到它们的核融合完成这一发育阶段的某些主要事件。
Karyogamy The fusion of two nuclei that exist within a common cytoplasm, as occurs in the formation of the zygote from two gametes. 核配：同一个细胞中两个核之间的融合现象称为核配，核配发生在两个配子结合成合子的过程中。
Plasmogamy in the absence of karyogamy (fusion of nuclei) occurs between fungal mycelia of different strains of some ascomycetes and basidiomycetes to form a heterokaryon. 未核配（核融合）的质配发生在不同株系的子囊菌和担子菌菌丝体之间以形成异核体。
