Overexpression of the pepper antimicrobial protein CaAMP1 gene regulates the oxidative stress- and disease-related proteome in Arabidopsis.

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
Proteomics facilitates our understanding of cellular processes and network functions in the plant defense response during abiotic and biotic stresses. Here, we demonstrate that the ectopic expression of the Capsicum annuum antimicrobial protein CaAMP1 gene in Arabidopsis thaliana confers enhanced tolerance to methyl viologen (MV)-induced oxidative stress, which is accompanied by lower levels of lipid peroxidation. Quantitative comparative proteome analyses using two-dimensional gel electrophoresis coupled with mass spectrometry identified some of the oxidative stress- and disease-related proteins that are differentially regulated by CaAMP1 overexpression in Arabidopsis leaves. Antioxidant- and defense-related proteins, such as 2-cys peroxiredoxin, L-ascorbate peroxidase, peroxiredoxin, glutathione S-transferase and copper homeostasis factor, were up-regulated in the CaAMP1 transgenic leaf tissues. In contrast, GSH-dependent dehydroascorbate reductase and WD-40 repeat family protein were down-regulated by CaAMP1 overexpression. In addition, CaAMP1 overexpression enhanced resistance to Pseudomonas syringae pv. tomato (Pst) DC3000 infection and also H(2)O(2) accumulation in Arabidopsis. The identified antioxidant- and defense-related genes were differentially expressed during MV-induced oxidative stress and Pst DC3000 infection. Taken together, we conclude that CaAMP1 overexpression can regulate the differential expression of defense-related proteins in response to environmental stresses to maintain reactive oxygen species (ROS) homeostasis.
