The crucial elements of the 'last step' of programmed cell death induced by kinetin in root cortex of V. faba ssp. minor seedlings.
Article in Plant cell reports, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
key messageKinetin-induced programmed cell death, manifested by condensation, degradation and methylation of DNA and fluctuation of kinase activities and ATP levels, is an autolytic and root cortex cell-specific process. The last step of programmed cell death (PCD) induced by kinetin in the root cortex of V. faba ssp. minor seedlings was explained using morphologic (nuclear chromatin/aggregation) and metabolic (DNA degradation, DNA methylation and kinases activity) analyses. This step involves: (1) decrease in nuclear DNA content, (2) increase in the number of 4',6-diamidino-2-phenylindole (DAPI)-stained chromocenters, and decrease in chromomycin A3 (CMA3)-stained chromocenters, (3) increase in fluorescence intensity of CMA3-stained chromocenters, (4) condensation of DAPI-stained and loosening of CMA3-stained chromatin, (5) fluctuation of the level of DNA methylation, (6) fluctuation of activities of exo-/endonucleolytic Zn(2+) and Ca(2+)/Mg(2+)-dependent nucleases, (7) changes in H1 and core histone kinase activities and (8) decrease in cellular ATP amount. These results confirmed that kinetin-induced PCD was a specific process. Additionally, based on data presented in this paper (DNA condensation and ATP depletion) and previous studies [increase in vacuole, increase in amount of cytosolic calcium ions, ROS production and cytosol acidification "in Byczkowska et al. (Protoplasma 250:121-128, 2013)"], we propose that the process resembles autolytic type of cell death, the most common type of death during development of plants. Lastly, the observations also suggested that regulation of these processes might be under control of epigenetic (methylation/phosphorylation) mechanisms.
