Can AtTZF1 act as a transcriptional activator or repressor in plants?
Article in Plant signaling & behavior, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
In animals, Tandem CCCH Zinc Finger (TZF) proteins can affect gene expression at both transcriptional and post-transcriptional levels. In Arabidopsis thaliana, AtTZF1 is a member of the TZF family characterized by a plant-unique tandem zinc finger motif. AtTZF1 can bind both DNA and RNA in vitro, and it can traffic between the nucleus and cytoplasmic foci. However, no in vivo DNA/RNA targets have been identified so far, and little is known about the molecular mechanisms underlying AtTZF1's profound effects on plant growth, development, and stress responses. In order to determine whether AtTZF1 can function as a transcription factor, transactivation assays were conducted. Results indicated that AtTZF1 fusion proteins could not exert obvious transcriptional activity in a maize protoplast transient expression system. However, this conclusion might be biased due to poor nuclear localization of AtTZF1 fusion proteins in the assay system.
