Bisphenol A causes melatonin biosynthesis epigenetic reprogramming of melatonin biosynthesis genes in arabidopsis thaliana.

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
Bisphenol A (BPA) is a widely used chemical that is commonly found in soils and surface waters worldwide and acts as an oxidative stressor on plants. Our understanding of how BPA exposure affects cellular redox homeostasis remains limited. We discovered that the epigenetic reprogramming of melatonin biosynthesis helps defend against oxidative stress induced by BPA in Arabidopsis. Five key BPA-responsive genes were identified, with AT1G26220 (encoding SNAT2) showing exceptional specificity to BPA and its analogs in various tissues. BPA binding to consecutive M1-M2 elements in the AT1G26220 promoter led to decreased H3K9ac and H3K14ac levels, subsequently significantly reducing AT1G26220's expression. It alters the melatonin biosynthesis pathway in order to maintain the redox homeostasis in plants by increasing the cellular antioxidative capacity and alleviating specific BPA-induced cellular damage. This epigenetic reprogramming changes the melatonin biosynthesis pathway, enhancing the dynamic redox homeostasis in plants. Additionally, this specific oxidative response in plants reduces the harmful effects of BPA to some extent. Our study finds a sophisticated and structure-specific epigenetic response to BPA in plants, providing a solid molecular mechanism that enhances our understanding of plant resistance to BPA at the cellular level and contributes to assessing BPA risks globally.
