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

introductionPlant-microbe collaborative remediation is a highly promising heavy metal remediation strategy. However, its remediation efficiency for manganese (Mn) tailings and its underlying mechanism remain inadequately explored.

objectivesThis study aimed to screen microbial strains capable of remediating Mn contamination and evaluate the potential of these strains to enhance the remediation of heavy metal-contaminated soils through plant-microbe interactions.

methodsBacterial strains with both Mn resistance and plant growth-promoting characteristics were isolated from the rhizosphere of plants in Mn tailings. Two selected strains were inoculated to the rhizosphere of 2-year-old Koelreuteria paniculata seedlings in non-polluted soil or in Mn tailings. The effectiveness of the strains in remediating Mn tailings was evaluated by measuring the growth, photosynthetic characteristics, antioxidant enzyme activity, Mn accumulation capacity of K. paniculata, and overall soil remediation effect.

resultsThis study selected two Mn resistance and plant growth-promoting bacteria, including Bacillus cereus (EA-1) and Priestia megaterium (BN-4). Functioanl groups identified by Fourier transform infrared spectroscopy (FTIR), such as hydroxyl and phosphate groups, are essential for Mn adsorption on the bacterial surface. In Mn tailings, inoculation with the BN-4 strain significantly increased superoxide dismutase (SOD) and catalase (CAT) activities in the leaves of K. paniculata by 201.57% and 34.48%, respectively, compared to the uninoculated treatment. However, inoculation with the EA-1 strain enhanced the root, stem, and leaf biomass, net photosynthetic rate, stomatal conductance, Mn accumulation, and bioconcentration factor (BCF) of K. paniculata by 72.70%, 47.82%, 51.32%, 81.38 %, 86.05%, 113.09% and 76.19%, respectively, compared to the uninoculated treatment.

conclusionConsidering the growth of K. paniculata and its capacity for Mn accumulation and BCF, inoculation with the EA-1 strain is a more favorable approach for remediation of Mn tailings.
