Abstract:
:To establish the gene transfer system in the cyanobacteria, we successfully introduced the shuttle plasmid pRL489 into Oscillatoria MKU 277 by electroporation with transformation frequencies of up to 102 cfu/mug of plasmid DNA. These findings suggest that Oscillatoria MKU 277 can be used as an experimental tool for genetic maneuvering.
