Replacement and amplification of bacterial genes with sequences altered in vitro.

Abstract

An efficient method for the replacement of chromosomal DNA by segments altered in vitro has been developed for bacteria. The method requires (i) a recombinant plasmid with a ColE1-like replicon and (ii) a strain defective in DNA polymerase I (polA), which is unable to replicate the plasmid extrachromosomally. This method is of general use since there are a number of suitable vectors and polA strains are available in both Escherichia coli and Salmonella typhimurium, the two most widely studied bacterial species. Using the method, we have constructed two chromosomal deletions in the chemotaxis gene region of S. typhimurium. In addition, plasmid sequences integrated into the chromosome have been amplified up to 30-fold by varying the concentration of ampicillin or tetracycline in the growth medium.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
