Chloroplast DNA of the duckweed Spirodela oligorrhiza, isolated by CsCl gradient centrifugation, was characterized by its buoyant density, guanine + cytosine content, melting behavior, circularity, and contour length. In all these characteristics, chloroplast DNA of S. oligorrhiza is similar to the chloroplast genomes of other higher plants, except that it has a significantly larger size.
通过 CsCl 梯度离心法分离的浮萍 Spirodela oligorrhiza 的叶绿体 DNA,其特征为浮力密度、鸟嘌呤+胞嘧啶含量、融解行为、环化程度和轮廓长度。在所有这些特性中,浮萍 S. oligorrhiza 的叶绿体 DNA 与其他高等植物的叶绿体基因组相似,但它的大小明显更大。
