Extracellular ATP activates an Arabidopsis plasma membrane Ca(2+)-permeable conductance.
Article in Plant signaling & behavior, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
Extracellular ATP has been found to elevate cytosolic free Ca(2+) in Arabidopsis thaliana and trigger gene transcription, suggesting that it acts as a plant cell regulator. Recent findings place extracellular ATP upstream of Arabidopsis thaliana NADPH oxidase activity and plasma membrane Ca(2+)-permeable channels in the root epidermis. Here we show that increasing extracellular ATP concentration evokes a larger but more irregular Ca(2+) influx conductance in root epidermal protoplasts. This may help modulate changes in cytosolic free Ca(2+) as a second messenger and help explain the dose-dependent effects of extracellular ATP on cell function. The receptors for ATP and the downstream plasma membrane Ca(2+) channels remain unknown at the protein or gene level. No equivalents of animal ATP receptors have been identified in higher plant genomes. We propose here that annexins could perceive extracellular ATP and participate in Ca(2+) influx.
