The lignin fluorescence at the base of the petals guiding the pollinators to the pollination chamber in Artabotrys hainanensis.
Article in BMC plant biology, 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
In Artabotrys hainanensis, the pollination chamber aperture of the flowers at the blooming stage is narrow, and only exposed in the pistillate phase. It is worth studying how the pollinating insects enter the pollination chambers accurately through the narrow aperture. During flowering, the dynamics of the opening and closing of the pollination chambers ensure that sufficient pollen is carried by pollinating beetles (Carpophilinae) facilitating successful pollination. A. hainanensis exhibits fluorescence at the base of the inner and outer whorls of petals, which marks the entrance to the pollination chamber, acting a role in pollinator attraction. The lignin content gradually accumulated as the trichomes in pollination chamber areas increase in density and volume during flower development, and the lignin fluorescent signals at the pollination chamber areas reach their brightest at the blooming stage. The green fluorescence emitted by lignin under visible light could attract beetles, which have visual receptors that are sensitive to green light. Therefore, the lignin fluorescence produced by trichomes that located at the aperture of the pollination chamber serves as a visual signal that guides the pollinating insects through the narrow pollination aperture and into the flower pollination chamber at anthesis. Further studies are required to determine if lignin-associated fluorescence signals occur in other species of the Annonaceae and if they represent a common trait within the family.
