Bacteria spring a surprise [PDF]
, 2014 Cell division involves the precise duplication of all the genetic material in the cell—both the chromosomes and the plasmid DNA—and the equal division of this material between the two daughter cells.

Microbiology Spectrum, 2014 ABSTRACT The stable maintenance of low-copy-number plasmids in bacteria is actively driven by partition mechanisms that are responsible for the positioning of plasmids inside the cell. Partition systems are ubiquitous in the microbial world and are encoded by many bacterial chromosomes as well as plasmids. These systems, although different in

Stoichiometry of P1 Plasmid Partition Complexes [PDF]
Journal of Biological Chemistry, 2000 The P1 plasmid prophage is faithfully partitioned by a high affinity nucleoprotein complex assembled at the centromere-like parS site. This partition complex is composed of P1 ParB and Escherichia coli integration host factor (IHF), bound specifically to parS. We have investigated the assembly of ParB at parS and its stoichiometry of binding.

Primordial origin and diversification of plasmids in Lyme disease agent bacteria
BMC Genomics, 2018 Background With approximately one-third of their genomes consisting of linear and circular plasmids, the Lyme disease agent cluster of species has the most complex genomes among known bacteria.

CDI Systems Are Stably Maintained by a Cell-Contact Mediated Surveillance Mechanism. [PDF]
PLoS Genetics, 2016 Contact-dependent growth inhibition (CDI) systems are widespread amongst Gram-negative bacteria where they play important roles in inter-cellular competition and biofilm formation. CDI+ bacteria use cell-surface CdiA proteins to bind neighboring bacteria

Mathematical and experimental approaches to the dimer catastrophe theory [PDF]
, 2011 Multicopy plasmids rely on random distribution for stable inheritance by daughter cells at division. Threats to plasmid copy number increase the probability of plasmid loss, which can be detrimental to both plasmid and host. Plasmid dimers emerge through

Analysis of the Nucleioprotein Complexes Essential for P1 Plasmid Partition [PDF]
, 2010 For all organisms, segregation and proper intracellular localization of DNA are essential processes in ensuring faithful inheritance of genetic material.

Sequence analysis of pKF3-70 in Klebsiella pneumoniae: probable origin from R100-like plasmid of Escherichia coli. [PDF]
PLoS ONE, 2010 BACKGROUND: Klebsiella pneumoniae is a clinically significant species of bacterium which causes a variety of diseases. Clinical treatment of this bacterial infection is greatly hindered by the emergence of multidrug-resistant strains.

Plasmid Partitioning by Human Tumor Viruses [PDF]
Journal of Virology, 2018 ABSTRACT The human tumor viruses that replicate as plasmids (we use the term plasmid to avoid any confusion in the term episome, which was coined to mean DNA elements that occur both extrachromosomally and as integrated forms during their life cycles, as does phage lambda) share many features in their DNA synthesis.

Plasmid Interactions Can Improve Plasmid Persistence in Bacterial Populations
Frontiers in Microbiology, 2020 It is difficult to understand plasmid maintenance in the absence of selection and theoretical models predict the conditions for plasmid persistence to be limited.
