Characterization of the Priestia megaterium ZS-3 siderophore and studies on its growth-promoting effects.
Article in BMC microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundThe ability of plant growth-promoting rhizobacteria (PGPR) to alleviate iron deficiency-induced chlorosis in plants has been widely reported, but the role of siderophores in the re-greening process has rarely been investigated. In this study, the Priestia megaterium ZS-3 (ZS-3) siderophore was first characterized, and a 100-fold concentration of the crude extract of the siderophore was extracted by solid-phase extraction and used to inoculate Arabidopsis thaliana to investigate whether the ZS-3 siderophore could alleviate plant iron deficiency-induced chlorosis in the presence of an insoluble iron source and to determine how it promoted plant growth.
resultsThe results indicated that -Fe + Fe
conclusionsThis study revealed that the ZS-3 siderophore Ferrioxamine E [M + Fe-2 H] enhances plant iron uptake and transport activity at the transcriptional level, confirming the important role of the ZS-3 siderophore in plant iron deficiency status, and the results suggest that the ZS-3 siderophore helps plants acquire iron, alleviates plant chlorosis and promotes plant growth through mechanism I of plant iron acquisition. In this study, we closely linked the structural characterization and quantification of siderophores with Fe deficiency-induced chlorosis to elucidate the promotional mechanism of siderophores in Fe-deficient environments.
