Involvement of the caleosin/peroxygenase RD20 in the control of cell death during Arabidopsis responses to pathogens.

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
Caleosins, mostly found in lipid droplets of seeds and leaves, are believed to play physiological roles through their enzymatic capacities to produce oxylipins. We recently identified the caleosin RD20 as a peroxygenase reducing endogenous fatty acid hydroperoxides into their corresponding alcohols. Such oxylipins confer tolerance to oxidative stress by decreasing reactive oxygen species accumulation and by minimizing cell death. RD20 expression being induced by pathogens, we have examined the mode of action of this caleosin in response to biotic stress. Plants overexpressing RD20 exhibited an alteration of their leaf cuticle wax components and an increased resistance to the fungus Alternaria brassicicola. Conversely, silencing RD20 led to an enhanced propagation of the fungus and to reduced severity of the damages caused by the inoculation of the bacteria Pseudomonas syringae pv tomato. We discuss these findings and propose that the major function of RD20 is to generate oxylipins modulating oxidative status and cell death.
