Prosystemin-derived signals: bridging leaf microbiome dynamics and defense activation.
Article in Environmental microbiome, 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
backgroundPlant-derived peptides can act as resistance inducers and represent promising tools for sustainable crop protection. Despite growing interest and application, their broader effects on plant-associated microbiomes remain insufficiently characterized. Here, we investigated the impact of an immunomodulatory peptide derived from the tomato defense protein Prosystemin on the tomato phyllosphere microbiome and leaf volatilome.
resultsThe peptide was applied as a foliar spray at biweekly intervals from planting to two months post-germination to approximate common agricultural practices. Shotgun metagenomic sequencing combined with qPCR revealed abundant bacterial communities (up to 4.6 log
conclusionBeyond its established role in protecting tomato against pests and necrotrophic fungi, the Prosystemin-derived peptide provides an opportunity to investigate peptide-triggered plant responses and their interactions with the plant microbiota.
