Transmission electron microscopic observation and hybridization study of the Plasmid from Spirulina platensis were carried out from June, 1992 to April, 1993.Supercoiled and closed circular patterns were observed under a transmission electron Wicroscope. The size of the plasmid from S6 strain was about 2.0kb, which Was slightly different from the result of electrophoresis. Results of dot blotting show that plasmids from strains of S6, F3, F3 spiral and F3 stfaight differing in form are komologous to each other and are also homologous to chromosomal DNAs.
