Natural competence for transformation [PDF]

Current Biology, 2016
While most molecular biologists are familiar with the artificial transformation of bacteria in the context of laboratory cloning experiments, natural competence for transformation refers to a specific physiological state in which prokaryotes are able to take up genetic material from their surroundings. Occasionally, such absorbed DNA is recombined into

Natural Transformation of Myxococcus xanthus [PDF]

Journal of Bacteriology, 2011
ABSTRACTMyxococcus xanthusbelongs to the delta class of the proteobacteria and is notable for its complex life-style with social behaviors and relatively large genome. Although previous observations have suggested the existence of horizontal gene transfer inM.

Genetic modification of Streptococcus dysgalactiae by natural transformation. [PDF]

mSphere
Streptococcus dysgalactiae is an emerging human and animal pathogen. Functional studies of genes involved in virulence of S. dysgalactiae and other pyogenic group streptococci are often hampered by limited genetic tractability.

Impact of Natural Transformation on the Acquisition of Novel Genes in Bacteria. [PDF]

Mol Biol Evol
International audienceNatural transformation is the only process of gene exchange under the exclusive control of the recipient bacteria. It has often been considered as a source of novel genes, but quantitative assessments of this claim are lacking.

On the Nature of the Tsallis–Fourier Transform [PDF]

Mathematics, 2015
By recourse to tempered ultradistributions, we show here that the effect of a q-Fourier transform (qFT) is to map equivalence classes of functions into other classes in a one-to-one fashion. This suggests that Tsallis’ q-statistics may revolve around equivalence classes of distributions and not individual ones, as orthodox statistics does.

A Transformation Rule for Natural Multiplicities [PDF]

International Mathematics Research Notices, 2020
Abstract For multiplicities arising from a family of ideals we provide a general approach to transformation rules for a ring extension that is étale in codimension one. Our result can be applied to bound the size of the local étale fundamental group of a singularity in terms of F-signature, recovering a recent result of Carvajal-Rojas ...

Automating Cloning by Natural Transformation [PDF]

ACS Synthetic Biology, 2020
Affordable and automated cloning platforms are essential to many synthetic biology studies. However, the traditional E. coli-based cloning is a major bottleneck as it requires heat shock or electroporation implemented in the robotic workflows. To overcome this problem, we explored bacterial natural transformation for automatic DNA cloning and ...

Transformation of Environmental Bacillus subtilis Isolates by Transiently Inducing Genetic Competence [PDF]

, 2010
Domesticated laboratory strains of Bacillus subtilis readily take up and integrate exogenous DNA. In contrast, ‘‘wild’’ ancestors or Bacillus strains recently isolated from the environment can only be genetically modified by phage transduction ...

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.

Natural transformation in Campylobacter species [PDF]

Journal of Bacteriology, 1990
Growing cells of Campylobacter coli and C. jejuni were naturally transformed by naked DNA without the requirement for any special treatment. Transformation frequencies for homologous chromosomal DNA were approximately 10(-3) transformants per recipient cell in C. coli and 10(-4) in C. jejuni.
