Journal ArticleDOI
Integration of foreign DNA during natural transformation of Acinetobacter sp. by homology-facilitated illegitimate recombination
TL;DR: It is found that the integration of foreign DNA into the genome of the Gram-negative Acinetobacter sp.
Journal ArticleDOI

Jana Lottmann,Holger Heuer,Johann de Vries,Andreas Mahn,Klaus Düring,Wilfried Wackernagel,Kornelia Smalla,Gabriele Berg +7 more
TL;DR: This work was the first approach to assess the establishment of plant growth promoting rhizobacteria and potential biocontrol agents on transgenic plants.
Journal ArticleDOI
The natural transformation of the soil bacteria Pseudomonas stutzeri and Acinetobacter sp. by transgenic plant DNA strictly depends on homologous sequences in the recipient cells.
TL;DR: The nptII+ gene present in the genome of transgenic potato plants transforms naturally competent cells of the soil bacteria Pseudomonas stutzeri and Acinetobacter BD413.

TL;DR: The findings reveal that short and damaged, including truly ancient, DNA molecules, which are present in large quantities in the environment, can be acquired by bacteria through natural transformation, suggesting that natural genetic exchange of DNA from dead and even extinct organisms to contemporary bacteria can take place over hundreds of thousands of years.
Journal ArticleDOI
Microbial horizontal gene transfer and the DNA release from transgenic crop plants
TL;DR: The results suggest that, although such transfers could be possible in principle, each of the many steps involved from the release of intact DNA from a plant cell to integration into a prokaryotic genome has such a low probability that a successful transfer event be extremely rare.
