证据表明，在白绢病菌菌核的生物发生与脂质过氧化作用。巩膜的初始显示100倍增加脂质过氧化物的总脂质相比，年轻的菌丝体生长在还原条件下（在2-巯基乙醇）在黑暗中，没有Fe（II）。菌核形成的数量与菌丝体中脂质过氧化水平有直接关系。在菌核渗出液中发现了可能的膜和细胞质来源的脂质过氧化物。本文提出了一种新的途径，以了解菌核形成的机制，在核菌rolfsii和其他真菌。在这项工作中的数据对脂质过氧化-最常见的诱发后果的氧自由基以及过去的实验数据，强烈表明，这种现象可能与氧化应激引起的生长条件。
Evidence is presented that the biogenesis of sclerotia in Sclerotium rolfsii is associated with lipid peroxidation. Sclerotial initials show 100-fold increase in lipid peroxides of their total lipids as compared with young mycelia grown under reducing conditions (in 2-mercaptoethanol) in dark and without Fe(II). There was a direct relationship between the number of sclerotia formed and lipid peroxidation levels in the mycelial colonies. Lipid peroxides of possible membranous and cytoplasmic origin were found in sclerotial exudate. Tn this paper a new approach is advanced for the understanding of the mechanism of sclerotial formation in Sclerolium rolfsii and in other fungi. The data in this work on lipid peroxidation - the most frequently evoked consequence of oxygen free radicals as well as the data of past experiments, strongly suggest that this phenomenon may be associated with oxidative stress caused by growth conditions.
