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

backgroundPre-harvest sprouting (PHS) poses an enormous threat to wheat production; enhancing seed dormancy is an effective strategy to mitigate PHS. However, as a highly complex trait, seed dormancy is governed by polygenes and is difficult to be enhanced in genetic manipulation.

resultsIn this study, a wheat mutant 1813WH was generated from a PHS-sensitive line “Long 13-3778” through EMS treatment. The mutant exhibited significantly enhanced seed dormancy with a germination index (GI) of only 4.57% (wild type: 42.77%, P < 0.01), accompanied by altered agronomic traits including reduced plant height and tillering, prolonged reproductive period, thicker internodes, increased grain size, and higher 1000-grain weight (P < 0.05); seed longevity was significantly improved, maintaining stable germination dynamics under accelerated aging treatment; metabolite detection showed that its raffinose content was 3.5 times that of the wild type, glutathione (GSH) content was 9.8 times, and the GSH/GSSG ratio was significantly increased (10.74 vs. wild type 0.68); combined transcriptomic and metabolomic analyses indicated significant enrichment of glutathione metabolism, galactose metabolism (related to raffinose family oligosaccharide synthesis), and tricarboxylic acid (TCA) cycle pathways, with decreased contents of TCA cycle intermediates and differential expression of key genes in related pathways.

conclusionThis study provided evidence for the potential relationship between seed dormancy and longevity, which may have broad implications for the conservation and utilization of germplasm resources, as well as new materials for wheat breeding aiming at enhancing seed dormancy and longevity.
