摘要
本文对不同生境下的钝顶螺旋藻Spirulina (Arthrospira) platensis进行了RAPD分析。结果表明,鄂尔多斯高原碱湖和Chad湖的钝顶螺旋藻基因组DNA扩增多态性片段同源性为48.23%。2个样品在分子遗传水平上存在着较大的差异,这是由于各自生态环境明显不同和长期地理隔离造成的。
The samples of Spirulina ( Arthrospira ) platensis from different habitats were analyzed by the RAPD, The result shows that there are obvious differences in the molecular level between the Spirulina (Arthrospira) platensis from alkaline lakes in Erdos Plateau and the one from Chad Lake, and the homology of DNA in the amplified polymorphism of the Spirulina (Arthrospira) platensis only reaches 48.23%. The different habitats and geographical isolation are the primary reasons for the above-mentioned result.
