通常所谓的菌蕈就是指担子菌的子实体,如蘑菇、香菇、金针菇、平菇、玉蕈、松口蘑以及灵芝等。菌蕈是由双核化的营养菌丝体在温度和光的刺激下形成子实体原基,它利用营养菌丝和培养基中的养分最后发育为成熟的子实体。只是由于有关菌蕈的生物化学研究开展较迟,因此我们对从营养菌丝转变为原基,进而从原基转变成子实体的生长机理了解甚少。当我们一旦探明了子实体形成的机制,必然就为野生食用菌的人工栽培提供重要的知识,对于生物分化领域课题的研究也必有重要的贡献。在此,笔者就首先发现的酸性蛋白酶的特异性抑制物质S-PI(Pepstatin Ac,即乙酰抑蛋白酶 The so-called fungal mushroom refers to the fruiting bodies of basidiomycetes, such as mushrooms, mushrooms, mushrooms, mushrooms, mushrooms, pine mushrooms and Ganoderma lucidum and so on. Fungus is a dual nucleated vegetative mycelium that forms the fruiting body primordium under the stimulation of temperature and light, which utilizes vegetative mycelium and nutrients in the medium to finally develop into mature fruiting bodies. Just because biochemical research on fungi has been delayed, we have little understanding of the growth mechanisms that change from vegetative hyphae to primordia and then from primordia to fruiting bodies. Once we have probed into the mechanism of the formation of fruiting bodies, we must provide important knowledge for the artificial cultivation of wild edible fungi. We must also make an important contribution to the research in the field of biological differentiation. Here, the author first discovered that the specific inhibitor of acid protease S-PI (Pepstatin Ac, that is,
