Arabidopsis PDE1 confers phosphate-deficiency tolerance in primary root growth.
Article in Plant cell reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 messagePDE1 acts as a mediator of primary root growth in response to Pi deficiency. Phosphorus is commonly considered as a limiting nutrient for plant growth, which is mainly due to the immobility and uneven distribution of phosphate (Pi) in soils so that available Pi is not adequate in the rhizosphere. Although various mediators have been identified in Pi sensing and response, more details need to be uncovered in plant Pi-deficiency tolerance. Here, we isolated a mutant, termed pde1 (phosphate-deficiency sensitive 1), showing the hypersensitive Pi-deficiency-induced growth inhibition of primary roots. PDE1 encodes a hydroxyphenylpyruvate reductase with rare activity in vitro and repressed by Pi deficiency. Histochemical analysis displayed that Pi-deprived pde1 accumulated more Fe and reactive oxygen species (ROS) in primary roots than the wild type (WT). Addition of ferrozine, a Fe
