Deciphering the physiological and molecular mechanisms for copper tolerance in autotetraploid Arabidopsis.
Article in Plant cell reports, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
key messageAutotetraploid Arabidopsis line esd and 4COL exhibit enhanced tolerance to Cu stress by enhancing activation of antioxidative defenses, altering expression of genes related to Cu transport, chelation, and ABA-responsive. Autopolyploidy is ubiquitous among angiosperms and often results in better adaptation to stress conditions. Although copper (Cu) is an essential trace element, excess amounts can inhibit plant growth and even result in death. Here, we report that autotetraploid Arabidopsis thaliana esd and 4COL exhibit higher tolerance to Cu stress. Under such conditions, tetraploid plants had lower Cu contents and significantly more biomass compared with diploid plants. When exposed to excess Cu for 24 h, levels of superoxide anions, hydrogen peroxide, and malondialdehyde were lower in tetraploids than in diploids. Moreover, activities of the antioxidant enzymes superoxide dismutase and peroxidase were stimulated and glutathione content was maintained at a relative higher level in the tetraploids. The expression of genes related to Cu transport and chelation was altered in autotetraploid Arabidopsis under Cu stress, and several key genes involved in the response to abscisic acid (ABA) were significantly up-regulated. Our results indicate that tetraploid Arabidopsis esd and 4COL acquire improved tolerance to Cu stress through enhanced activation of antioxidative defense mechanisms, altered expression of genes related to Cu transport and chelation, and positive regulation of expression for ABA-responsive genes.
