Response of Arabidopsis thaliana to N-hexanoyl-DL-homoserine-lactone, a bacterial quorum sensing molecule produced in the rhizosphere.
Article in Planta, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 76 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
The bacterial quorum sensing signals N-acyl-L: -homoserine lactones enable bacterial cells to regulate gene expression depending on population density, in order to undertake collective actions such as the infection of host cells. Only little is known about the molecular ways of plants reacting to these bacterial signals. In this study we show that the contact of Arabidopsis thaliana roots with N-hexanoyl-DL: -homoserine-lactone (C6-HSL) resulted in distinct transcriptional changes in roots and shoots, respectively. Interestingly, unlike most other bacterial signals, C6-HSL influenced only a few defense-related transcripts. Instead, several genes associated with cell growth as well as genes regulated by growth hormones showed changes in their expression after C6-HSL treatment. C6-HSL did not induce plant systemic resistance against Pseudomonas syringae. The inoculation of roots with different types of AHLs led predominantly for short chain N-butyryl-DL: -homoserine lactone and C6-HSL to root elongation. Determination of plant hormone concentrations in root and shoot tissues supported alterations of auxin to cytokinin ratio. Finally, we provide evidence that Arabidopsis takes up bacterial C6-HSL and allows systemic distribution throughout the plant. In sum, the bacterial quorum sensing signal C6-HSL does induce transcriptional changes in Arabidopsis and may contribute to tuning plant growth to the microbial composition of the rhizosphere.
