Volatile-Mediated Plant Defense Networks: Field Evidence for Isoprene as a Short-Distance Immune Signal.
Article in Plant, cell & environment, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Isoprene, the most abundant biogenic hydrocarbon in the atmosphere, is known to protect photosynthesis from abiotic stress and significantly impact atmospheric chemistry. While laboratory studies show that isoprene can enhance plant immunity, its role in plant-plant communication under natural field conditions remains unclear. In a 2-year field experiment, we used wild-type and transgenic silver birch (Betula pendula) lines with enhanced isoprene emission levels to examine their impact on neighboring Arabidopsis thaliana, including wild-type and immune signaling mutants (llp1: legume lectin-like protein 1; jar1: jasmonate resistant 1). Receiver plants exposed to higher isoprene levels showed increased resistance to Pseudomonas syringae, independent of jasmonate signaling but dependent on LLP1, a protein essential for systemic acquired resistance. Volatile analysis indicated isoprene as an airborne molecule that can also trigger an immune response in neighboring plants along with other terpenoids. Our study using transgenic birches in a complex environment provides new insights into the molecular mechanisms underlying plant volatile perception and expands our understanding of plant chemical communication in terrestrial ecosystems.
