Ti plasmids of Agrobacterium as conjugative plasmids
Nature, 1977THE relationship of the plant-oncogenic properties of Agrobacterium tumefaciens to the presence in these strains of large plasmids (the Ti plasmids) has now been convincingly demonstrated in several ways: oncogenic strains cured of the Ti plasmid lose their oncogenicity irreversibly1–3; transfer of Ti plasmids to non-oncogenic plasmidless strains ...

Plasmid Profile Typing and Plasmid Fingerprinting
2003Plasmids are extra-chromosomal molecules of deoxyribonucleic acid (DNA) capable of autonomous replication. Such molecules have been identified in many bacterial genera and usually exist as covalently closed circular (CCC) molecules. Plasmids range in size from less than one megaDalton (MDa) to several hundred MDa.

Critical Reviews in Biotechnology, 1997
This review describes Lactobacillus plasmids on distribution, structure, function, vector construction, vector stability, application, and prospective. About 38% of species of the genus Lactobacillus were found to contain plasmids with different sizes (from 1.2 to 150 kb) and varied numbers (1 or more). Some Lactobacillus plasmids with small sizes were

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.

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, 1978
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 ...
