This study shows that the superoxide radical (O(2) *( -)), a direct indicator of oxidative stress, is involved in the differentiation of the phytopathogenic filamentous fungi Rhizoctonia solani, Sclerotinia sclerotiorum, Sclerotium rolfsii and Sclerotinia minor, shown by using superoxide dismutase (SOD) mimetics to decrease their sclerotial differentiation. The production rate of O(2) *(-) and SOD levels in these fungi, as expected, were significantly lowered by the SOD mimetics, with concomitant decrease of the indirect indicator of oxidative stress, lipid peroxidation.
本研究表明，超氧自由基（O(2) *( -)）作为氧化应激的直接指标，参与了植物病原丝状真菌立枯丝核菌、核盘菌、罗耳伏革菌和小核盘菌的分化，这可通过使用超氧化物歧化酶（SOD）模拟物来降低其菌核分化来证明。这些真菌的 O(2) *(-)产生率和 SOD 水平如预期的那样，被 SOD 模拟物显著降低，同时氧化应激的间接指标，脂质过氧化也随之降低。
