DNA uptake during bacterial transformation
Nature Reviews Microbiology, 2004Naturally competent bacteria are able to take up exogenous DNA and undergo genetic transformation. The transport of DNA from the extracellular milieu into the cytoplasm is a complex process, and requires proteins that are related to those involved in the assembly of type IV pili and type II secretion systems, as well as a DNA translocase complex at the

Bacterial Transformations of and Resistances to Heavy Metals
1984Bacteria carry out chemical transformations of heavy metals. These transformations (including oxidation, reduction, methylation, and demethylation) are sometimes byproducts of normal metabolism and confer no known advantage upon the organism responsible. Sometimes, however, the transformations constitute a mechanism of resistance.

Genomic Insights into Bacterial DMSP Transformations
Annual Review of Marine Science, 2012Genomic and functional genomic methods applied to both model organisms and natural communities have rapidly advanced understanding of bacterial dimethylsulfoniopropionate (DMSP) degradation in the ocean. The genes for the two main pathways in bacterial degradation, routing DMSP to distinctly different biogeochemical fates, have recently been identified.

If one consults any genetics textbook written before the mid-1970s, one will find much on the transformation of such bacterial species as Bacillus subtilis, but no mention of Escherichia coli. The method now most generally used for introducing DNA into E.

Impact of heat shock step on bacterial transformation efficiency
Molecular Biology Research Communications, 2016CaCl2 treatment followed by heat shock is the most common method for artificial transformation. Here, the cells were transformed using CaCl2 treatment either with heat shock (standard protocol) or without heat shock (lab protocol) to comprehend the ...

Current Status of Bacterial Transformations
1955Publisher Summary When it became clear that a number of plant viruses are crystallizable macromolecules composed of ribonucleic acid and protein, it was possible to attribute to a particular sort of macromolecule the striking biological property of autoreproduction.

Molecular mechanism of genetic recombination in bacterial transformation
Zeitschrift f�r Vererbungslehre, 1964B. subtilis cells auxotrophic for two linked markers (ind-his, ind-tyr, his-tyr) have been transformed by means of DNA preparations obtained by hybridization of wild type DNA with the DNA of a strain auxotrophic for one of the linked markers. It was established that hybridization does not increase the transforming activity of DNA for the heterozygous ...

Induced transformation of amorphous silica to cristobalite on bacterial surfaces
, 2015Extreme conditions such as high temperature and/or pressure are usually required for the transformation of amorphous silica to crystalline polymorphs. In this article, we present our results that amorphous silica can be deposited on a bacterial surface ...

Postreplication targeting of transformants by bacterial immune systems?
Trends in Microbiology, 2013Bacteria are constantly challenged by foreign genetic elements such as bacteriophages and plasmids. Several defense systems provide immunity against such attackers, including restriction-modification (R-M) systems and clustered, regularly interspaced short palindromic repeats (CRISPRs).
