Evolutionary conservation of MLO gene promoter signatures.
Article in BMC plant biology, 2019. 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
backgroundPowdery mildew (PM) is a widespread fungal disease of plants in temperate climates, causing significant economic losses in agricultural settings. Specific homologs of the MLO gene family are PM susceptibility factors, as their loss-of function results in durable PM resistance (mlo resistance) in several plant species. The role of MLO susceptibility genes in plant-pathogen interactions is still elusive, however it is known that they are strongly upregulated following PM infection.
resultsIn this study, we investigated the structure of 414 Putative Promoter Regions (PPRs) of MLO genes and highlighted motif and regulatory element patterns related to genomic relationships among species and phylogenetic distance among homologs. A TC box-like motif and a thymine-rich motif were found to be overrepresented in MLO genes transcriptionally upregulated upon infection with PM fungi. As proof of concept, we showed that the expression of a melon (Cucumis melo L.) gene enriched for the motifs above mentioned was strongly upregulated upon infection with the PM fungus Podosphaera xanthii.
conclusionWhile identifying a candidate MLO susceptibility gene in melon, this study provides insight on the transcriptional control of MLO genes and indicates diagnostic features useful to identify MLO susceptibility genes across species affected by the PM disease.
