Metabolic changes contributing to large biomass production in the Arabidopsis ppGpp-accumulating mutant under nitrogen deficiency.
Article in Planta, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
MAIN
conclusionThe Arabidopsis ppGpp-overproducing mutant indicates a larger biomass than wild type by modulated amino-acid metabolism under nitrogen-limiting conditions. The regulatory nucleotide, guanosine 3', 5'-bis(pyrophosphate; ppGpp)-originally identified in Escherichia coli-controls gene expression and enzyme activities in the bacteria and plastids of plant cells. We recently reported that the ppGpp over-producing mutant of Arabidopsis thaliana had a larger shoot weight than wild type (WT), especially under nutrient-deficient conditions. However, the mechanisms behind the influence of ppGpp on plant growth and biomass remain elusive. To understand the impact of the ppGpp accumulation on plant growth, we characterized metabolic changes in the ppGpp-overproducing mutant upon transition from nitrogen-rich to nitrogen-limiting concentrations. We found that the fresh weight of the mutant was significantly larger than WT when the total nitrogen source (KNO
