Horizontal gene transfer in aminoacyl-tRNA synthetases including leucine-specific subtypes.
Article in Journal of molecular evolution, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Aminoacyl-tRNA synthetases catalyze a fundamental reaction for the flow of genetic information from RNA to protein. Their presence in all organisms known today highlights their important role in the early evolution of life. We investigated the evolutionary history of aminoacyl-tRNA synthetases on the basis of sequence data from more than 200 Archaea, Bacteria, and Eukaryota. Phylogenetic profiles are in agreement with previous observations that many genes for aminoacyl-tRNA synthetases were transferred horizontally between species from all domains of life. We extended these findings by a detailed analysis of the history of leucyl-tRNA synthetases. Thereby, we identified a previously undetected case of horizontal gene transfer from Bacteria to Archaea based on phylogenetic profiles, trees, and networks. This means that, finally, the last subfamily of aminoacyl-tRNA synthetases has lost its exceptional position as the sole subfamily that is devoid of horizontal gene transfer. Furthermore, the leucyl-tRNA synthetase phylogenetic tree suggests a dichotomy of the archaeal/eukaryotic-cytosolic and bacterial/eukaryotic-mitochondrial proteins. We argue that the traditional division of life into Prokaryota (non-chimeric) and Eukaryota (chimeric) is favorable compared to Woese's trichotomy into Archaea/Bacteria/Eukaryota.
