【摘要】 <正> 超氧物歧化酶(SOD)能催化超氧物阴离子自由基发生歧化作用而生成分子氧和过氧化氢,从而能防御活性氧对机体的伤害和衰老作用。Asada曾用SOD研究微生物的进化。我们发现Glycine属种间SOD谱型的差别,可供Glycine分类参考。林凤起等把SOD酶谱用于苹果种间分类研究,并绘制了苹果属9个种的亲缘关系图。本文分析Oryza属15个种的SOD谱型,发现酶谱型与染色体组型间有密切关系,栽培稻与野生稻的SOD谱型也有一定规律。可供Oryza分类,进化研究参考。更多还原

【Abstract】 Superoxide dismutase zymogram patterns of 15 species of the Genus Orvza were analyzed. There were 10 zymogram patterns, Ⅰ to Ⅹ, in Genus Oryza. The zymogram pattern, in general, was similar for the species with the same genome. Therefore, superoxide dismutase electrophoresis can be used as a biochemical index for taxonomic and genetic studies.更多还原
