Natural plasmid transformation in Escherichia coli.
Although Escherichia coli does not have a natural transformation process, strains of E. coli can incorporate extracellular plasmids into cytoplasm 'naturally' at low frequencies. A standard method was developed in which stationary phase cells were concentrated, mixed with plasmids, and then plated on agar plates with nutrients which allowed cells to grow. Transformed cells could then be selecte...
متن کاملF'Cm Plasmid of Escherichia coli
A strain of Pasteurella pestis, harboring the F'Cm plasmid from Escherichia coli, was able to donate its chromosome to auxotrophic recipient strains of P. pestis. The frequency of gene transfer in P. pestis was approximately 10-6 per donor cell, 100 times less efficient than gene transfer in Pasteurella pseudotuberculosis, but efficient enough to determine entry times for the markers histidine,...
متن کاملTransformation of Escherichia coli with a large plasmid of Acidiphilium multivorum AIU 301 encoding arsenic resistance.
Acidiphilium multivorum AIU 301 isolated from acid mineral water had strong arsenic resistance. This bacterium harbored a number of plasmids with different molecular sizes. A plasmid of 56 kbp, named pKW301, was isolated from A. multivorum AIU 301. When pKW301 was transferred into Escherichia coli JM109 by electroporation, an E. coli transformant carrying pKW301 exhibited resistance to sodium a...
متن کاملConstruction of an Escherichia coli-Clostridium perfringens shuttle vector and plasmid transformation of Clostridium perfringens.
A stable shuttle vector which replicates in Escherichia coli and Clostridium perfringens was constructed by ligating a 3.6-kilobase (kb) fragment of plasmid pBR322 with C. perfringens plasmid pHB101 (3.1 kb). The marker for this shuttle plasmid originated from the 1.3-kb chloramphenicol resistance gene of plasmid pHR106. The resulting shuttle vector, designated pAK201, is 8 kb in size and codes...
متن کاملPlasmid transformation in Haemophilus influenzae.
Purified 34-megadalton-plasmid deoxyribonucleic acid from antibiotic-resistant strains of Haemophilus influenzae transforms competent strains of H. influenzae more efficiently if the recipient strains contain certain other 30-megadalton plasmids.
