Cloning, sequencing, and characterization of the Azospirillum brasilense fhuE gene.
Article in Current microbiology, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The fhuE gene of Escherichia coli encodes the FhuE protein, which is a receptor protein in the coprogen-mediated siderophore iron-transport system. A fhuE gene homologue from Azospirillum brasilense, a nitrogen-fixing soil bacterium that lives in association with the roots of cereal grasses, was cloned, sequenced, and characterized. The A. brasilense fhuE encodes a protein of 802 amino acids with a predicted molecular weight of approximately 87 kDa. The deduced amino-acid sequence showed a high level of homology to the sequences of all the known fhuE gene products. The fhuE mutant was sensitive to iron starvation and defective in coprogen-mediated iron uptake. The mutant failed to express one membrane protein of approximately 78 kDa that was induced by iron starvation in the wild type. Complementation studies showed that the A. brasilense fhuE gene, when present on a low-copy number plasmid, could restore the functions of the mutant. Mutation in fhuE gene did not affect nitrogen fixation.
