1 · What the graph read from it

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.

2 · The registry

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

The study aimed to explore the genetic and functional potential of mycorrhizal helper bacteria (MHB) strains isolated from polluted soil, focusing on their ability to enhance plant growth and ameliorate the adverse effects of polycyclic aromatic hydrocarbons (PAHs). We sequenced the genomes of three MHB strains isolated from soil contaminated with PAHs and phenol. Moreover, experiments were carried out to check if these bacteria have ability to stimulate the growth of arbuscular mycorrhizal fungi (AMF) and promote plant development. Phylogenomic analysis identified the strains as belonging to the Streptomyces, Pantoea, and Bacillus genera, all exhibiting high tolerance to hydrocarbons. Genome mining revealed genes encoding enzymes for the degradation of aromatic compounds, alongside biosynthetic gene clusters for secondary metabolites such as siderophores and antibiotics. Laboratory experiments confirmed that the studied MHB strains enhance AMF development and spore production while exhibiting plant growth-promoting mechanisms such as siderophore and ammonia production, phosphate solubilization, and cellulolytic enzyme synthesis. These findings highlight the potential application of MHB in microbial-assisted remediation of hydrocarbon-contaminated soils through the tripartite plant-MHB-AMF system.
