3.原生质体的融合细胞融合的自然现象在真菌中是普遍存在的。布勒(Buller)等早已报道在多细胞真菌孢子中,其细胞隔膜间具有小孔沟通;各大类真菌的菌丝具有不同形式的孔隔,用以交流细胞质而又控制细胞核的混乱;菌丝融合现象在不完全菌类中屡见不鲜,籍此交流细胞核,产生异核体,起准性生殖的作用, 3. Protoplast Fusion The natural phenomenon of cell fusion is common in fungi. Buller et al. Have long reported that in the multicellular fungal spores, there are pinholes communicating between the cell membranes; the hyphae of various classes of fungi have different forms of cell septa to exchange cytoplasm and control the disruption of the nucleus; The phenomenon of silk fusion is not uncommon in incomplete fungi, so exchange nuclei, produce heterokaryons, the role of the role of the prospective reproductive,
