Article in Plant cell reports, 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
key messageOfERF106 protein binds to the promoter region of the ethylene biosynthesis gene OfACS2 and activates its expression, thereby accelerating the aging process of Osmanthus fragrans petals. Osmanthus fragrans is a multipurpose ornamental plant that combines landscaping utility, aesthetic appeal, and aromatic fragrance, granting it considerable economic and horticultural value. However, its value is substantially constrained by the short overall flowering period and the brief longevity of individual petals. The key regulatory genes, their functions, and the molecular mechanisms underlying petal senescence in O. fragrans remain largely unknown. Here, we identified a critical gene, OfERF106, from transcriptomic data. The expression level of OfERF106 peaked at the flower fading stage and was significantly higher than that observed during the primary and full blooming stages. The full-length sequence of OfERF106 contains a 675 bp open reading frame encoding 225 amino acids. Subcellular localization analysis confirmed that OfERF106 protein is localized in the nucleus. Overexpression of OfERF106 in Arabidopsis thaliana resulted in a flowering period shortened by 3-4 days compared to the control, indicating its role in promoting petal senescence. The functional validation of OfERF106 through rapid overexpression and silencing in O. fragrans petals further supported this result. Moreover, the expression levels of two ethylene biosynthesis-related genes (OfACS1 and OfACS2) were also significantly altered. Further analysis using yeast one-hybrid (Y1H) and dual luciferase (DLR) assays demonstrated that OfERF106 protein binds to the promoter of OfACS2 and activates its expression. These results suggest that OfERF106 accelerates petal senescence in O. fragrans by enhancing OfACS2 expression, which in turn promotes ethylene biosynthesis. Our study provides preliminary insights into the molecular mechanism regulating petal senescence in O. fragrans and highlights the functional role of OfERF106 in this process.
