The results of screening of 29 diverse cyanobacterial (blue-green algal) strains for plasmid (CCC DNA) content are reported. Approximately one-half of the strains were shown to contain one or more CCC DNAs. CCC DNAs from four unicellular marine cyanobacteria were characterized in more detail. These strains contained multiple plasmids. Two kinds of Southern hybridization experiments allowed us to show that different plasmids within the same strain, and different plasmids within different strains, can ( but do not always) contain restricted regions of sequence homology. We suggest that these regions of homology may be analogous to the transposable genetic elements of bacterial plasmids. This, together with indirect but compelling evidence for interspecific (or intergeneric) plasmid transfer, indicates that CCC DNAs (although as yet genetically cryptic) may play a role in the ecology and evolution of obligately autotrophic prokaryotes, as they do in the ecology and evolution of the better-known heterotrophic bacteria.
