In vitro effects of Bacillus velezensis strain Mandacaium against Xanthomonas citri pv. glycines: genomic and metabolomic insights.

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
Biological agents offer an alternative to chemical pesticides in managing plant diseases, as they help decrease environmental contamination and reduce selective pressure for resistant pathogens. In this study, bacteria isolated from the larval food of stingless bees were tested for in vitro antibacterial activity against Xanthomonas citri pv. glycines, the cause of soybean bacterial pustule. A strain identified as Bacillus velezensis showed notable growth inhibition in agar diffusion tests. Fractionation of the bacterial culture supernatant revealed that antimicrobial activity was concentrated in the metabolic fraction, especially in the ethyl acetate extract, which exhibited a concentration-dependent inhibition (CDI) of 0.015 mg/mL against X. citri pv. glycines. A phytotoxicity test using soybean seeds indicated no immediate effects on germination under experimental conditions. LC-MS analysis of the bioactive fraction tentatively identified 15 metabolites, mainly diketopiperazines, although other molecular features remained unknown. Whole-genome sequencing showed a genome size of about 4.0 Mb and 13 predicted biosynthetic gene clusters, including those likely involved in lipopeptide and polyketide production; however, these compounds were not detected in the analyzed extract. These findings demonstrate in vitro antibacterial activity linked to metabolites produced by a newly characterized Bacillus velezensis strain mandacaium and outline its biosynthetic potential at the genomic level. The results lay the groundwork for future in planta research to assess its role in sustainable plant disease management.
