Identification and analysis of VOCs released by Rhodococcus ruber GXMZU2400 to promote plant growth and inhibit pathogen growth.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
A strain of Rhodococcus ruber was isolated from the rhizosphere of Spartina alterniflora. The VOCs released by this strain effectively promote the growth of Arabidopsis thaliana and inhibit several plant pathogenic fungi, including Bipolaris sorokiniana, Cryphonectria parasitica, Fusarium oxysporum, Fusarium pseudograminearum, and Plectosphaerella cucumerina. SPME/GC-MS analysis revealed that the strain produces dimethyl disulfide (DMDS) and dimethyl trisulfide (DMTS), with DMDS being the predominant component of the volatile organic compounds (VOCs). It was observed that the growth of A. thaliana was enhanced under fumigation with DMDS and DMTS. Furthermore, these compounds effectively inhibited the aforementioned plant pathogenic fungi, with DMTS demonstrating a lethal effect on plant pathogenic fungi. Previous studies have confirmed that DMDS and DMTS promote the growth of A. thaliana. In this study, we found that DMTS could significantly enhance plant growth and inhibit plant pathogenic fungi even at low dosages. Transcriptome analysis indicated that the growth-related genes of A. thaliana were significantly upregulated in response to treatment with VOCs from R. ruber. Additionally, VOCs induced changes in multiple plant defense response genes and promoted the C4 pathway.
