LasR receptor for detection of long-chain quorum-sensing signals: identification of N-acyl-homoserine lactones encoded by the avsI locus of Agrobacterium vitis.
Article in Current microbiology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Bacterial biosensor strains have greatly facilitated the rapid discovery, isolation, and study of quorum-sensing systems. In this study, we determined the relative sensitivity of a LasR-based E. coli bacterial bioluminescence biosensor JM109 (pSB1075) for 13 diverse long-chain N-acyl-homoserine lactones (AHLs) including oxygen-substituted and -unsubstituted AHLs containing 14, 16, and 18 carbons and with and without double bonds. Furthermore, we show by bioassay, HPLC, and GC/MS that four long-chain AHLs of the C16-HSL family are encoded by the avsI gene of Agrobacterium vitis strain F2/5, a non-tumorigenic strain that inhibits pathogenic strains of A. vitis from causing crown gall on grape. The four C16-HSLs include: C16-HSL, N-hexadecanoyl homoserine lactone; 3-oxo-C16-HSL, N-(3-oxohexadecanoyl)homoserine lactone; C16:1-HSL, N-(cis-9-octadecenoyl)homoserine lactone; and 3-oxo-C16:1-HSL, N-(3-oxo-cis-11-hexadecenoyl)homoserine lactone. Thus, the LasR-based bioluminescent biosensor tested in this study should serve as a useful tool for the detection of various long-chain AHLs with and without double bonds as well as those oxylated at the third carbon from uninvestigated species.
