A temperature-sensitive mutation in the dnaE gene of Caulobacter crescentus that prevents initiation of DNA replication but not ongoing elongation of DNA.
Article in Journal of bacteriology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A genetic screen for cell division cycle mutants of Caulobacter crescentus identified a temperature-sensitive DNA replication mutant. Genetic complementation experiments revealed a mutation within the dnaE gene, encoding the alpha-catalytic subunit of DNA polymerase III holoenzyme. Sequencing of the temperature-sensitive dnaE allele indicated a single base pair substitution resulting in a change from valine to glutamic acid within the C-terminal portion of the protein. This mutation lies in a region of the DnaE protein shown in Escherichia coli, to be important in interactions with other essential DNA replication proteins. Using DNA replication assays and fluorescence flow cytometry, we show that the observed block in DNA synthesis in the Caulobacter dnaE mutant strain occurs at the initiation stage of replication and that there is also a partial block of DNA elongation.
