The Arabidopsis thaliana METACASPASE IIf Regulates Sugar Metabolism and Delays Dark-Induced Leaf Senescence.

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
The Arabidopsis thaliana METACASPASE IIf (AtMCA-IIf) is expressed during both developmental cell death and leaf senescence in Arabidopsis thaliana. It has been shown to contribute to developmental cell death but its role in regulating leaf senescence has remained unclear. To investigate this, we conducted dark-induced senescence assays using atmca-IIf mutant lines, which exhibited an accelerated senescence phenotype accompanied by increased levels of glycolytic sugars in light and slow degradation of starch in dark-incubated leaves. Our findings therefore support AtMCA-IIf function in leaf senescence through modulation of sugar metabolism. We propose, on the basis of both in vitro and in vivo data, that one of the proteolytic targets of AtMCA-IIf in this process is PFP
