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

Bacteria communicate via small diffusible molecules and thereby mediate group-coordinated behavior, a process referred to as quorum sensing. The prototypical quorum sensing system found in Gram-negative bacteria consists of a LuxI-type autoinducer synthase that produces N-acyl homoserine lactones (AHLs) as signals and a LuxR-type receptor that detects the AHLs to control expression of specific genes. However, many proteobacteria have proteins with homology to LuxR receptors yet lack any cognate LuxI-like AHL synthase. Here we show that in the insect pathogen Photorhabdus luminescens the orphan LuxR-type receptor PluR detects endogenously produced α-pyrones that serve as signaling molecules at low nanomolar concentrations. Additionally, the ketosynthase PpyS was identified as pyrone synthase. Reconstitution of the entire system containing PluR, the PluR-target operon we termed pcf and PpyS in Escherichia coli demonstrated that the cell-cell communication circuit is portable. Our research thus deorphanizes a signaling system and suggests that additional modes of bacterial communication may await discovery.
