The buoyant density of nuclear and mitochondrial deoxyribonucleic acid (DNA) from 14 species of fungi was determined by CsCl density gradient equilibrium centrifugation. The buoyant density of both types of DNA was the same for all three Mucorales analyzed. The buoyant density of mitochondrial DNA was significantly lower than that of the nuclear DNA for nine species of Ascomycetes and two species of Basidiomycetes. No simple correlation could be obtained from the comparison of the two types of DNA. Mitochondrial DNA represented a very small proportion of total DNA. Heat-denatured mitochondrial DNA renatured more readily than nuclear DNA.
通过氯化铯密度梯度平衡离心法测定了14种真菌的核脱氧核糖核酸(DNA)和线粒体脱氧核糖核酸(DNA)的浮力密度。在所分析的所有三种毛霉目中,两种类型DNA的浮力密度相同。对于9种子囊菌和2种担子菌,线粒体DNA的浮力密度显著低于核DNA。从两种类型DNA的比较中无法得出简单的相关性。线粒体DNA在总DNA中所占比例非常小。热变性的线粒体DNA比核DNA更容易复性。
