Misregulation of phosphoinositides in Arabidopsis thaliana decreases pollen hydration and maternal fertility.
Article in Sexual plant reproduction, 2011. 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
Phosphoinositides are important lipids involved in membrane identity, vesicle trafficking, and intracellular signaling. In recent years, phosphoinositides have been shown to play a critical role in polarized secretion in plants, as perturbations of phosphoinositide metabolism, through loss of function mutants, result in defects in root hair elongation and pollen tube growth, where polarized secretion occurs rapidly. In the Brassicaceae, responses of stigmatic papillae to compatible pollen are also thought to involve highly regulated secretory events to facilitate pollen hydration and penetration of the pollen tube through the stigmatic surface. We therefore sought to analyze the female sporophyte fertility of the root hair defective4-1 mutant and the PI 4-kinase β1/β2 double mutant, which differentially affect phosphatidylinositol-4-phosphate (PI4P) levels. Stigmas from both mutants supported slower rates of pollen grain hydration, and the fecundity of these mutants was also diminished as a result of failed pollination events. This study therefore concludes that PI4P is integral to appropriate pistil responses to compatible pollen.
