Physical separation of plasmid molecules to be inherited by daughter cells during cell division. In addition to regulating their replication and copy number in the host cell, thus propagating vertically within the bacterial population, some plasmids can spread horizontally between neighboring bacterial cells and transfer accessory genes that help bacteria to adapt to new . The high prevalence of antibiotic heteroresistance in pathogenic bacteria is mainly caused by gene amplification. Plasmids are double-stranded, self-replicating DNA segments with a few kilobases that are often found in gram-negative and gram-positive bacterial strains, as well as various fungi, including unicellular yeasts. Type IV CRISPRCas systems are thus believed to have a role in mediating interplasmid competition. 1979;43 Pt 1:409-17 Community shifts of soybean stem-associated bacteria responding to different nodulation phenotypes and N levels.

Researchers explain how the replication of bacterial plasmids starts If the plasmid is lost in a daughter cell, the antitoxin is rapidly degraded and the stable toxin kills the plasmid-free cell. Front. General Concepts The term 'plasmid' was originally proposed by J. Lederberg in 1952 to identify extrachromosomal hereditary structures. This is solved, in circular plasmids, by two main strategies: (i) opening of the strands followed by RNA priming (theta and strand displacement replication) or (ii) cleavage of one of the DNA strands to generate a 3'-OH end (rolling-circle replication).
