Function of Arabidopsis CPL1 in cadmium responses.
Article in Plant signaling & behavior, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Transcriptional and post-transcriptional responses to external iron (Fe) availability are essential for the cellular Fe homeostasis. Fe deficiency strongly induces Fe utilization-related gene expression; however, little is known about the early Fe signaling that regulates expression of a central transcription factor FIT. In Arabidopsis, mutations in RNA polymerase II CTD-phosphatase-like 1 (CPL1) enhance the expression of Fe utilization-related genes including FIT under Fe deficiency. Fe content is significantly increased in the roots and decreased in the shoots of cpl1-2 plants, and root growth of the cpl1-2 mutant shows higher tolerance to Fe deficiency and to toxicity of cadmium (Cd). The cpl1-2 plants accumulate more Cd in the shoots, suggesting that Cd toxicity in the cpl1-2 roots is circumvented by the transport of excess Cd to the shoots. Here we show data suggesting that the root-to-shoot translocation of Cd in cpl1-2 is mediated by yet uncharacterized Cd transport mechanisms.
