1 · What the graph read from it

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.

2 · The registry

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

Abies beshanzuensis is a critically endangered conifer species in the Pinaceae family, with only three wild adult trees (progenitor trees) remaining in its native habitat. To conserve its germplasm, A. beshanzuensis scions were grafted onto A. firma rootstocks, which significantly improved the growth and reproduction of the grafted plants. However, the effects of grafting on the growth and development of progeny of grafted A. beshanzuensis, as well as the underlying mechanisms, remain unclear. In this study, we compared seedling-stage growth differences between progeny of progenitor trees (PP) and grafted trees (GP), revealing significantly greater plant height and stem diameter in GP. Physiological analysis of leaf tissues showed significantly higher auxin levels in GP, increased chlorophyll content and enhanced maximum photochemical efficiency (Fv/Fm) compared to PP. De novo transcriptome assembly using PacBio and Illumina RNA-Seq identified 2,638 differentially expressed genes (DEG) between PP and GP, with significant changes in genes involved in auxin signaling and chlorophyll biosynthesis pathways in GP. Methylation-sensitive amplified polymorphism (MSAP) analysis further revealed a lower average DNA methylation level in GP compared to PP. We propose that grafting reduces DNA methylation-mediated repression of genes involved in the auxin signaling and chlorophyll synthesis, thereby enhancing seedling vigor and photosynthetic capacity. These findings provide a theoretical foundation and novel insights for the conservation of endangered woody plants, with broader implications for biodiversity preservation in the context of global climate change.
