Transcriptomic analysis supports the role of CATION EXCHANGER 1 in cellular homeostasis and oxidative stress limitation during cadmium stress.

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
Investigation of genetic determinants of Cd tolerance in the Zn/Cd hyperaccumulator Arabidopsis halleri allowed the identification of the vacuolar Ca(2+)/H(+) exchanger encoding CAX1 gene. CAX1 was proposed to interfere with the positive feedback loop between Reactive Oxygen Species (ROS) production and Cd-induced cytosolic Ca(2+) spikes, especially at low external Ca(2+) supply. In this study expression of genes involved in ROS homeostasis, cell wall composition, apoplastic pH regulation and Ca(2+) homeostasis were monitored in Arabidopsis thaliana wild-type and cax1-1 knock-out mutant and in Arabidopsis halleri wild-type exposed to cadmium or in control conditions. Clustering the outputs of the expression analysis in a gene co-expression network revealed that CAX1 and genes involved in Ca(2+) cellular homeostasis, apoplastic pH and oxidative stress response were highly correlated in A. thaliana, but not in A. halleri. Many of the studied genes were already highly expressed in A. halleri and/or their expression was not modified by exposure to Cd. The results further supported the role of CAX1 in the regulation of cytosolic ROS accumulation as well as the existence of different cell wall modifications strategies in response to Cd in Arabidopsis thaliana and halleri.
