A strategy for building an amplified transcriptional switch to detect bacterial contamination of plants.
Article in Plant molecular biology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
We have designed and tested a transcriptional autofeedback loop that could be used to engineer plants to sense the presence of bacteria. The signal amplification circuit was built based on the biological switch responsive to the presence of bacterial flagellin. Several flagellin- and E. coli-inducible Arabidopsis promoters were cloned and tested in transient expression assays in Arabidopsis and lettuce protoplasts using a flagellin-based peptide. These were investigated either as direct drivers of a reporter gene, or as a component of a transcriptional autofeedback loop. Arabidopsis promoters from the xyloglucan endotransglucosylase/hydrolase 18 (ATXTH18) and cytochrome P450 family CYP82C3 monooxygenase worked well as biological switches. These promoters were incorporated into our feedback loop system for signal amplification. The inclusion of a transcriptional repressor reduced basal expression, thereby increasing fold-amplification of signal detection and fine-tuning the positive autofeedback loop regulation.
