Defense responses of soybean roots during exposure to cadmium, excess of nitrogen supply and combinations of these stressors.

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
Heavy metal pollution is a serious environmental problem in agricultural soils since the uptake of heavy metals by plants represents an entry point into the food chain and is influenced by the form and amount of nitrogen (N) fertilization. Here we studied the defense responses in soybean roots exposed to ions of cadmium (applied as 50 mg l(-1) Cd(2+)) when combined with an excessive dose of N in form of NH(4)NO(3). Our data indicate that despite of stunted root growth, several stress symptoms typically observed upon cadmium treatment, e.g. peroxidation of lipid membranes or activation of chitinase isoforms, become suppressed at highly excessive N. At the same time, other defense mechanisms such as catalases and proline accumulation were elevated. Most importantly, the interplay of ongoing responses resulted in a decreased uptake of the metal into the root tissue. This report points to the complexity of plant defense responses under conditions of heavy metal pollution combined with intensive fertilization in agriculture.
