Macroevolution of plasmids: A model for plasmid speciation
Journal of Theoretical Biology, 1992A new evolutionary model for diversification in plasmid incompatibility groups (plasmid speciation) is suggested. The model is based on the formation of plasmid cointegrates from two compatible plasmids. The existence of plasmid cointegrates is well known, however, their potential key role in plasmid macroevolution has not yet been recognized.

Plasmid, 1982
Abstract Thirty-two Listeria strains, including L. monocytogenes of the different Seeliger serovars, L. grayi and L. murrayi, have been analyzed for the presence of plasmids. A cryptic plasmid of 38.5 Md was found in seven strains: in four L. monocytogenes (serovars 1 2 c , 4b, 4d, and Ivanov 1), and in both the L.

Abstract In this paper is presented a brief review of the current state of information on plasmid incompatibility followed by a detailed mathematical model dealing with incompatibility between autonomous homogenic plasmids and based on the assumption that the intracellular plasmid copy pool is randomized with respect to assortment during cell ...

Plasmid Copy Number and Plasmid Stability
2003Many expression systems in research and industry use plasmids as vectors for the production of recombinant proteins or non-proteinous recombinant substances. Plasmids have an essential impact on productivity. Related factors are plasmid copy number, structural plasmid stability and segregational plasmid stability.

Plasmid Segregation Mechanisms [PDF]
Annual Review of Genetics, 2005 Bacterial plasmids encode partitioning (par) loci that ensure ordered plasmid segregation prior to cell division. par loci come in two types: those that encode actin-like ATPases and those that encode deviant Walker-type ATPases. ParM, the actin-like ATPase of plasmid R1, forms dynamic filaments that segregate plasmids paired at mid-cell to daughter ...

Bacterial plasmids are extra-chromosomal, covalently-closed circular (CCC) molecules of DNA that are capable of autonomous replication (1). Plasmids may contain genes for a variety of phenotypic traits, such as antibiotic resistance, virulence, or metabolic activities, although some plasmids comprise genes conferring no detectable phenotype and are ...

It is a quarter century since the publications of evidence for the transmissibility of drug resistance among Enterobacteria (1,48). Although it was not the beginning of plasmid research, it was that discovery that led to the great expansion of work on plasmids, their natural history, and the uses to which they can be put. By their practical importance,
