ABSTRACT
DNA amplification fingerprinting (DAF) of 17 cyanobacterial isolates belonging to symbiotic and free-living forms of 6 different genera was done. The dendrogram analysis of 17 cyanobacterial cultures revealed three major clusters. All Westiellopsis cultures formed the first major cluster and their nucleotide relatedness ranged between 71-93%. In the second major cluster, the symbiotic cyanobacterium Anabaena sp dominated and all Anabaena cultures showed 60-75% similarity with each other. Nostoc muscorum is related to Anabaena variabilis by 85% and formed the third major cluster. The dendrogram analysis of cyanobacterial isolates clearly revealed that free-living cyanobacterial cultures were closely related with each other and were diverse from the symbiotic forms.
