Transcriptomic analysis reveals key genes and pathways involved in fruit abscission of Epimedium pubescens.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundFruit abscission in Epimedium pubescens is a critical yet underexplored process affecting seed yield and agricultural efficiency. Here, we integrated transcriptomic analyses across three developmental stages (pre-abscission, abscission zone formation, and post-abscission) to unravel the molecular underpinnings of fruit shedding.
resultWe identified 1,009 significant DEGs in the comparison between stage B and stage A, and 1,388 significant DEGs in the comparison between stage B and stage C. Enriched in lignin biosynthesis, starch-sucrose metabolism, and plant hormone signaling pathways. Key lignin-related genes (e.g., COMT, CAD) were upregulated during abscission formation, correlating with enhanced cell wall fortification. Concurrently, dynamic shifts in starch synthesis/degradation enzymes (e.g., glgC, AAM) and trehalose metabolism genes (TPS, TPP) highlighted energy reallocation and stress adaptation. Ethylene and abscisic acid signaling dominated late-stage abscission, while auxin and cytokinin pathways were active earlier. Subcellular localization revealed expansin (EXP) and lipase (GDSL) genes localized at the cell wall, implicating their roles in wall modification and detachment.
conclusionsThese findings delineate a regulatory network integrating hormonal cross-talk, metabolic reprogramming, and cell wall dynamics, offering targets for improving seed retention in Epimedium cultivation.
