A DNase encoded by integrated element CJIE1 inhibits natural transformation of Campylobacter jejuni [PDF]

, 2009
The species Campylobacter jejuni (C. jejuni) is considered naturally competent for DNA uptake and displays strong genetic diversity. Nevertheless, non-naturally transformable strains and several relatively stable clonal lineages exist.

The natural extension of the ?-transformation

Acta Mathematica Hungarica, 1996
For each real number β>1 the β-transformation is dened by Tβx = βx(mod1). In this paper the natural extension Tβ of the ergodic system underlying Tβ is explicitly given. Furthermore, it is shown that a certain induced system of this natural extension is Bernoulli. Since Tβ is weakly mixing, due to W. Parry, it follows from a deep result of A.

rpoN1, but not rpoN2, is required for twitching motility, natural competence, growth on nitrate and virulence of Ralstonia solanacearum

Frontiers in Microbiology, 2015
The plant pathogen Ralstonia solanacearum has two genes encoding for the sigma factor 54: rpoN1, located in the chromosome and rpoN2, located in a distinct ‘megaplasmid’ replicon.

Bacterial Transformation Buffers Environmental Fluctuations through the Reversible Integration of Mobile Genetic Elements

mBio, 2020
Horizontal gene transfer (HGT) promotes the spread of genes within bacterial communities. Among the HGT mechanisms, natural transformation stands out as being encoded by the bacterial core genome.

Natural Transformation of Gallibacterium anatis [PDF]

Applied and Environmental Microbiology, 2012
ABSTRACT Gallibacterium anatis is a pathogen of poultry. Very little is known about its genetics and pathogenesis. To enable the study of gene function in G. anatis , we have established methods for transformation and targeted mutagenesis.

Prophage-Dependent Neighbor Predation Fosters Horizontal Gene Transfer by Natural Transformation

mSphere, 2020
Natural transformation is a broadly conserved mechanism of horizontal gene transfer (HGT) in bacteria that can shape their evolution through the acquisition of genes that promote virulence, antibiotic resistance, and other traits.
