High-voltage electroporation of bacteria: genetic transformation of Campylobacter jejuni with plasmid DNA.
Electroporation permits the uptake of DNA by mammalian cells and plant protoplasts because it induces transient permeability of the cell membrane. We investigated the utility of high-voltage electroporation as a method for genetic transformation of intact bacterial cells by using the enteric pathogen Campylobacter jejuni as a model system. This report demonstrates that the application of high-v...
متن کاملGenetic transformation of Rhodopseudomonas sphaeroides by plasmid DNA.
A broad-host-range cloning vector, pUI81, was constructed in vitro from plasmids RSF1010 and pSL25 (a pBR322 derivative) and used to assay for transformation in Rhodopseudomonas sphaeroides. Washing cells with 500 mM Tris was an effective means of inducing competence for DNA uptake. Transformation frequencies as high as 10(-5) (transformants per viable cell) have been achieved by incubating Tri...
متن کاملGenetic transformation of Rhizobium leguminosarum by plasmid DNA.
We demonstrated the genetic transformation of Rhizobium leguminosarum by R68.45 plasmid DNA by freezing and thawing cell suspensions in the presence of R68.45 plasmid DNA and 20 mM MgCl2. Clones resistant to kanamycin and tetracycline were recovered at a frequency of 10(-8) per recipient cell. No colonies that were doubly drug resistant were recovered in parallel control experiments.

متن کاملElectroporation of Haemophilus influenzae is effective for transformation of plasmid but not chromosomal DNA
Electroporation of plasmid and chromosomal DNAs were tested in Haemophilus influenzae because of an interest in introducing DNA into mutants that are deficient in competence for transformation. The initial experiments were designed to investigate and optimize conditions for electroporation of H. influenzae. Plasmid DNA was introduced into the competence proficient strain Rd and its competence-d...
