Evidence for a Xer/dif system for chromosome resolution in archaea. [PDF]
PLoS Genetics, 2010 Homologous recombination events between circular chromosomes, occurring during or after replication, can generate dimers that need to be converted to monomers prior to their segregation at cell division.

Promoter Orientation of Prokaryotic Phase-variable Genes by PCR
Bio-Protocol, 2012 One major mechanism of phase variable gene expression in prokaryotes is through inversion of the promoter element for a gene or operon. This protocol describes how to detect the promoter orientation of a phase-variable gene by PCR.

Tyrosine Recombinase Retrotransposons and Transposons
Microbiology Spectrum, 2015 ABSTRACT Retrotransposons carrying tyrosine recombinases (YR) are widespread in eukaryotes. The first described tyrosine recombinase mobile element, DIRS1, is a retroelement from the slime mold Dictyostelium discoideum . The YR elements are bordered by terminal repeats related to their replication via free

FtsK-dependent dimer resolution on multiple chromosomes in the pathogen Vibrio cholerae. [PDF]
PLoS Genetics, 2008 Unlike most bacteria, Vibrio cholerae harbors two distinct, nonhomologous circular chromosomes (chromosome I and II). Many features of chromosome II are plasmid-like, which raised questions concerning its chromosomal nature.

Resolution of Mismatched Overlap Holliday Junction Intermediates by the Tyrosine Recombinase IntDOT [PDF]
Journal of Bacteriology, 2017 ABSTRACT CTnDOT is an integrated conjugative element found in Bacteroides species. CTnDOT contains and transfers antibiotic resistance genes. The element integrates into and excises from the host chromosome via a Holliday junction (HJ) intermediate as part of a site-specific recombination mechanism.

Initial characterization of the Pf-Int recombinase from the malaria parasite Plasmodium falciparum.
PLoS ONE, 2012 BackgroundGenetic variation is an essential means of evolution and adaptation in many organisms in response to environmental change. Certain DNA alterations can be carried out by site-specific recombinases (SSRs) that fall into two families: the serine ...

The complete plastid genomes of the two 'dinotoms' Durinskia baltica and Kryptoperidinium foliaceum. [PDF]
PLoS ONE, 2010 In one small group of dinoflagellates, photosynthesis is carried out by a tertiary endosymbiont derived from a diatom, giving rise to a complex cell that we collectively refer to as a 'dinotom'.

Flipping chromosomes in deep-sea archaea. [PDF]
PLoS Genetics, 2017 One of the major mechanisms driving the evolution of all organisms is genomic rearrangement. In hyperthermophilic Archaea of the order Thermococcales, large chromosomal inversions occur so frequently that even closely related genomes are difficult to ...

PLoS ONE, 2022 The exchange of antimicrobial resistance (AMR) genes between aquaculture and terrestrial microbial populations has emerged as a serious public health concern. However, the nature of the mobile genetic elements in marine bacteria is poorly documented.
