Chloroplast-associated metabolic functions influence the susceptibility of maize to Ustilago maydis.
Article in Molecular plant pathology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Biotrophic fungal pathogens must evade or suppress plant defence responses to establish a compatible interaction in living host tissue. In addition, metabolic changes during disease reflect both the impact of nutrient acquisition by the fungus to support proliferation and the integration of metabolism with the plant defence response. In this study, we used transcriptome analyses to predict that the chloroplast and associated functions are important for symptom formation by the biotrophic fungus Ustilago maydis on maize. We tested our prediction by examining the impact on disease of a genetic defect (whirly1) in chloroplast function. In addition, we examined whether disease was influenced by inhibition of glutamine synthetase by glufosinate (impacting amino acid biosynthesis) or inhibition of 3-phosphoshikimate 1-carboxyvinyltransferase by glyphosate (influencing secondary metabolism). All of these perturbations increased the severity of disease, thus suggesting a contribution to resistance. Overall, these findings provide a framework for understanding the components of host metabolism that benefit the plant versus the pathogen during a biotrophic interaction. They also reinforce the emerging importance of the chloroplast as a mediator of plant defence.
