Auxin-Rich Extract from Pseudomonas rhodesiae Enhances Cadmium Tolerance and Uptake in Cattail.
Article in Current microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Cadmium (Cd) pollution has become an increasing environmental and public health concern. Phytoremediation offers a sustainable strategy for metal removal, and its efficiency can be enhanced by microbial-derived biostimulants. This study investigated an auxin-rich culture supernatant extract from Pseudomonas rhodesiae GRC140 as a biostimulant to improve Cd tolerance and uptake in cattail (Typha latifolia). The supernatant extract, obtained after 84 h of bacterial growth in Luria Bertani medium supplemented with 0.1% L-tryptophan, was characterized by Fourier Transform Infrared (FTIR) spectroscopy, thin layer chromatography (TLC), and gas chromatography-mass spectrometry (GC-MS), confirming the presence of indole-3-acetic acid, indole-3-ethanol, indole, and indole-3-lactic acid. At a low concentration (1.15 mg/L), the extract increased shoot length by 30%, whereas higher concentrations (≥ 2.3 mg/L) inhibited root growth. Under Cd stress, the supernatant extract enhanced shoot biomass and chlorophyll content, reduced electrolyte leakage, and modulated antioxidant defense system in roots. Furthermore, the extract increased Cd accumulation in roots, reduced Cd translocation to shoots, and improved total Cd removal in hydroponic systems. FTIR analysis of root tissues suggested possible cell wall modifications associated with Cd sequestration. These findings indicate that bacterial supernatant extracts may serve as sustainable biostimulants for phytoremediation purposes.
