Phylogenetic distribution of branched RNA-linked multicopy single-stranded DNA among natural isolates of Escherichia coli
Open accessAbstract
Multicopy single-stranded DNA (msDNA), a branched DNA-RNA molecule, has been shown in Escherichia coli B and clinical strain Cl-1 to be synthesized by reverse transcriptase. We report that 13% of the strains of the ECOR collection, a sample of 72 E. coli isolates representing the breadth of genetic variation of the species, produce msDNA. Three of the four major subspecific groups include msDNA-producing strains. Screening of 25 isolates that are genetically related to msDNA-producing clinical strains uncovered 22 additional msDNA-producing strains. A phylogenetic tree based on allelic variation detected electrophoretically at 20 enzyme-encoding loci revealed two major clusters and several deep branches composed of strains that synthesize msDNA. Although E. coli K-12 does not harbor msDNA, other closely related strains of the K-12 family do. The results support the hypothesis that msDNA-synthesizing systems, including reverse transcriptase genes, were acquired recently and independently in different lineages of E. coli.

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.
