Bacterial cell-free supernatants as metabolite-based biostimulants for alleviating salinity stress in plants.
Review in Frontiers in plant science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Soil salinity severely limits global crop productivity, affecting approximately 20% of irrigated land under changing climate conditions. It impairs water uptake, disrupts nutrient balance, and induces oxidative stress, leading to significant yield losses, particularly in salt-sensitive crops. This review evaluates the potential of metabolite-rich bacterial cell-free supernatants (CFS) derived from plant growth-promoting bacteria (PGPB) as biostimulants for mitigating salinity stress in crops including soybean, canola, and wheat. CFS contain diverse bioactive compounds, including phytohormones, osmolytes, antioxidants, microbe-to-plant signal compounds and nutrient-solubilizing agents, which enhance plant performance through mechanisms such as modulation of hormonal signaling, activation of antioxidant defenses, and regulation of ion homeostasis. Compared to living-cell microbial inoculants, CFS offer advantages in stability and regulatory acceptance. However, their practical application is constrained by variability in composition, lack of standardized protocols, and limited field validation. Addressing these challenges through targeted research and field studies will be critical to enable the adoption of CFS-based strategies for climate-resilient agriculture.
