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

backgroundBroussonetia papyrifera, a novel forage tree species, exhibits a notable ability to accumulate selenium, making it a viable option for selenium enrichment feed. Nevertheless, the molecular mechanisms governing selenium metabolism in this tree are poorly understood, hindering its further development as a selenium accumulator.

resultsThis study revealed 47 WRKY transcription factors from the B. papyrifera genome. These WRKY transcription factors were characterized by their gene structure, protein domains, and synteny analysis across different species. Based on the phylogenetic analysis, these WRKY genes were categorized into three distinct subfamilies. By integrating transcriptomic and physiological data, nine WRKY genes were strongly correlated with selenium. Subsequently, quantitative qRT-PCR results further confirmed BpWRKY34 and BpWRKY25 as potential regulators of selenium metabolism in B. papyrifera, subcellular localization studies indicated that BpWRKY34 and BpWRKY25 were functional in the cell nucleus. Furthermore, we identified several miRNAs that potentially target WRKY family members. Co-expression network analysis revealed downstream enzymatic networks functionally linked to WRKY transcription factors in the selenium metabolic pathway of B. papyrifera.

conclusionsThe integrated analysis of BpWRKY genes identified candidate genes that regulate selenium metabolism, offering a theoretical foundation for developing Se-enriched B. papyrifera through genetic improvement.
