In this study , genetic diversity of various strains of spirulina platensis is analyzed with rapd molecular marker and antibiotics marker , the results are compared with their morphologic characters , aimed at constructing a more reasonable classification criterion and knowing more about the genetic background of spirulina . additionally , it is found that under the cultivated condition the linear filament can retransite to the normal curved one which is similar to original spiral filament
本论文利用rapd分子标记及抗生素抗性标记分析了不同钝顶螺旋藻品系的遗传多态性，并与其形态学特征进行了比较，以期建立更合理的螺旋藻分类方法及加深对螺旋藻遗传背景的了解；同时，发现在养殖环境下变直藻丝体可以回变为正常螺旋形态的现象。
