1 · What the graph read from it

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.

2 · The registry

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 165-kb megaplasmid pAO1 of Arthrobacter nicotinovorans carries two large gene clusters, one involved in nicotine catabolism (nic-gene cluster) and one in carbohydrate utilization (ch-gene cluster). Here, we propose that both gene clusters were acquired by A. nicotinovorans by horizontal gene transfer mediated by pAO1. Protein-protein blast search showed that none of the published Arthrobacter genomes contains nic-genes, but Rhodococcus opacus carries on its chromosome a nic-gene cluster highly similar to that of pAO1. Analysis of the nic-genes in the two species suggested a recombination event between their nic-gene clusters. Apparently, there was a gene exchange between pAO1, or a precursor plasmid, and a nic-gene cluster of an as yet unidentified Arthrobacter specie or other soil bacterium, possibly related to Rhodococcus, leading to the transfer by pAO1 of this catabolic trait to A. nicotinovorans. Analysis of the pAO1 ch-gene cluster revealed a virtually identical counterpart on the chromosome of Arthrobacter phenanthrenivorans. Moreover, the sequence analysis of the genes flanking the ch-gene cluster suggested that it was acquired by pAO1 by Xer-related site directed recombination and transferred via the plasmid to A. nicotinovorans. The G+C content, the level of sequence identity, gene co-linearity of nic- and ch-gene clusters as well as the signs of recombination events clearly supports the notion of pAO1 and its precursor plasmids as vehicles in HGT among Gram + soil bacteria.
