Dual Roles of Bacillus velezensis ES-120 in Plant Disease Suppression and Growth Promotion.

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
Beneficial plant-associated microbes such as Bacillus species have important potential uses as bioinoculants that reduce dependence on agricultural chemicals. These microbes produce diverse metabolites that enhance plant resilience, but the functions of these compounds and the associated plant hormone pathways remain unclear. Using Bacillus velezensis ES-120, a novel strain isolated from Chenopodium album L., we demonstrate that distinct classes of ES-120 metabolites play different roles. Using Arabidopsis thaliana, we show that non-volatile soluble metabolites produced by ES-120, including lipopeptides identified by reversed-phase high-performance liquid chromatography, exhibit biocontrol activity by inhibiting multiple soil-borne pathogens. In contrast, volatile organic compounds (VOCs) emitted by ES-120 promote plant growth, likely by modulating auxin and brassinosteroid (BR) signalling pathways, with effects sustained across diverse conditions. Headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry identified multiple VOCs produced by ES-120. Individual compounds showed limited activity, suggesting that growth promotion may depend on interactions among multiple VOCs or on an undetected low-abundance compound. In greenhouse trials, ES-120 reduced wilt in tomato (Solanum lycopersicum) and increased the biomass of Chinese cabbage (Brassica rapa var. chinensis). Thus, B. velezensis ES-120 functions as a dual-purpose bioinoculant: its soluble metabolites suppress soil-borne pathogens and its VOCs enhance plant growth via auxin and BR pathways, highlighting its potential for sustainable agriculture.
