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

backgroundCitrus rootstock selection plays a critical role in modulating sugar-acid metabolism, thereby influencing fruit flavor quality. This study systematically investigated the dynamic changes in sugar and acid components, key enzyme activities, and related gene expression in 'Newhall' navel orange (Citrus sinensis) grafted onto Citrus reticulata (Rt), Citrus junos (Cj), and Poncirus trifoliata (Pt) rootstocks during fruit development (150-240 days after flowering, DAF).

resultsPt significantly enhanced late-stage sucrose accumulation (48.86 ± 2.63 mg·g⁻¹), surpassing the means of Rt and Cj by 26.78% and 60.72% at 240 DAF, respectively. This was associated with elevated sucrose synthase (SS) activity and upregulated CsSS2 expression. In contrast, Rt rootstock promoted malic and quinic acid retention and exhibited the highest citrate synthase (CS), isocitrate dehydrogenase (IDH), and isocitrate lyase (ICL) activities, supported by significantly increased upregulation of acid metabolism genes (CsCS1, CsNADP-IDH1/2/3). Comprehensive evaluation using the TOPSIS model, weighted by entropy analysis (with tartaric acid, fructose, and glucose identified as primary determinants), ranked fruit quality as Pt > Rt > Cj at maturity.

conclusionsThese findings establish a mechanistic framework linking rootstock-specific regulation of enzymatic activities and gene expression with dynamic sugar-acid profiles, providing valuable insights for optimizing rootstock-scion combinations to enhance citrus flavor quality.
