Plasmids isolated from marine sediment microbial communities contain replication and incompatibility regions unrelated to those of known plasmid groups
Article Abstract:
The distribution and diversity of plasmids within marine microbial populations of coastal California marine sediments were analyzed by deoxyribonucleic acid (DNA) hybridization. Molecular analysis and DNA hybridization of plasmids isolated from gram-negative and gram-positive marine eubacteria indicated the presence of novel incompatibility and replication regions. Furthermore, hybridization was not detected in the plasmids that are isolated from coastal California's marine sediment bacterial community.

Isolation of broad-host-range replicons from marine sediment bacteria
Article Abstract:
Research was conducted to examine the isolation of broad-host-range replicons from marine sediment bacteria. The characterization of naturally occurring plasmids isolated from heterotrophic bacterial isolates originating from coastal California marine sediments was carried out by studying their incompatibility and replication properties. Results indicate that there may be similar mechanisms for plasmid replication initiation in the indigenous plasmids of gram-negative marine sediment bacteria.

Endogenous isolation of replicon probes for assessing plasmid ecology of marine sediment microbial communities
Article Abstract:
Research describes a collection of replicon probes derived from endogenously isolated marine plasmids and their use in evaluating plasmid distribution and ecology in marine communities. Data suggest that marine sediment bacteria possess broad-host-range plasmids.
