In re-extracted DNA obtained shortly after uptake of transforming DNA by Bacillus subtilis, increased amounts of donor DNA radioactivity banding at the position of donor-recipient DNA complex (DRC) are observed in CsCl gradients, if the cells are irradiated with high doses of UV prior to reextractio

β¦ Synopsis
Hybrid plasmids were constructed in which the transcription of regions of inserted DNA was defined. Cells containing these plasmids were transformed with monomeric forms of a different hybrid plasmid, which contained, however, the same inserted DNA as the resident plasmid. The transformation frequencies observed indicated that transcription of homologous DNA in resident plasmids and also tertiary DNA structure interfered with transformation.

Previously it was demonstrated that, in contrast to the homologous donor-recipient complex, the unstable heterologous donor-recipient complex remains bound to the cellular membrane. To examine whether proteins known to be involved in the processing of transforming DNA in Bacillus subtilis are associ
Transformation of competent cells of Bacillus subtilis with antibiotic resistance plasmid DNA has shown that (a) competence for plasmid and chromosomal DNA develops with similar kinetics; (b) DNA linearized with a variety of restriction endonucleases does not transform; (c) CCC plasmid DNA is inacti
The involvement of microbial interactions in natural transformation of bacteria was evaluated using an aquatic model system. For this purpose, the naturally transformable Bacillus subtilis was used as the model bacterium which was co-cultivated with the protist Tetrahymena thermophila (a consumer) a
Although heterospecific transformation is extremely inefficient and very little heterologous donor DNA integrates into the recipient chromosome in a stable way, we have previously shown that B. pumilus DNA entering competent B. subtilis efficiently associates with the recipient chromosome in an unst
