Comparison of four constitutive promoters for the expression of transgenes in the tropical nitrogen-fixing tree Allocasuarina verticillata.
Article in Plant cell reports, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Allocasuarina verticillata is an actinorhizal tree that lives in symbiotic association with a nitrogen fixing actinomycete called Frankia. In the search for promoters that drive strong constitutive expression in this tropical tree, we studied the organ specificity of four different constitutive promoters (CaMV 35S, e35S, e35S-4ocs and UBQ1 from Arabidopsis thaliana) in stably transformed A. verticillata plants. The ss-glucuronidase (gus) gene was used as a reporter and expression studies were carried out by histochemical analyses on shoots, roots and actinorhizal nodules. While the 35S promoter was poorly expressed in the shoot apex and lateral roots, both the e35S and e35S-4ocs were found to drive high constitutive expression in the transgenic non-nodulated plants. In contrast, the UBQ1 promoter was very poorly expressed and appeared unsuitable for A. verticillata. We also showed that none of the promoters studied were active in the nodule infected cells, whatever the developmental stage studied.
