Adaptive evolution of highly mutable loci in pathogenic bacteria

Moxon, E.Richard, Rainey, Paul B., Nowak, Martin A., Lenski, Richard E.·1994·Current Biology

Abstract

Bacteria have specific loci that are highly mutable. We argue that the coexistence within bacterial genomes of such 'contingency' genes with high mutation rates, and 'housekeeping' genes with low mutation rates, is the result of adaptive evolution, and facilitates the efficient exploration of phenotypic solutions to unpredictable aspects of the host environment while minimizing deleterious effects on fitness.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Previous explanations for possible mechanisms underlying chromosomal inversion included illegitimate recombination, intra-chromosomally homologous recombination, and integrase-mediated site-specific recombination.

    “Based on these molecular evidences, previous explanations for the possible mechanisms underlying chromosomal inversion included illegitimate recombination,51–53 intra-chromosomally homologous recombination,54 as well as integrase-mediated site-specific recombination.55 , 56”

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.
