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

Flag leaf morphology (FLM) is a critical determinant of wheat (Triticum aestivum L.) photosynthetic efficiency and grain yield. Chinese endemic wheat, a unique genetic reservoir formed by long-term adaptation to diverse and heterogeneous environments in China, harbors abundant, untapped allelic variation for traits related to environmental resilience and yield architecture. Mining this distinctive germplasm is therefore essential for identifying novel genetic determinants underlying complex traits like FLM. In this study, a genome-wide association study was conducted on 182 Chinese endemic wheat accessions using 38,490 single-nucleotide polymorphisms. We identified four stable quantitative trait loci (QTL) associated with FLM traits, three of which for flag leaf width (QFLW.sau.5A, QFLW.sau.5B, and QFLW.sau.5D) were intriguingly located on the homoeologous chromosomes of group 5, suggesting the action of a conserved, multi-subgenome genetic system. None of these QTLs overlapped with previously reported loci, highlighting their novelty and the value of this endemic gene pool. Pleiotropic analysis revealed that these loci also influence plant height and spike architecture. Their breeding value was further confirmed by validation in an independent population. Thirteen high-confidence candidate genes with elevated expression in flag leaf tissue were predicted, many involved in leaf development, photosynthesis, and stress responses. Collectively, by mining the unique genetic diversity of Chinese endemic wheat, we have uncovered a novel, homoeologous QTL system and candidate genes for FLM. These findings provide both a conceptual advance in understanding the polyploid genetic architecture of this key trait and valuable functional targets/molecular markers for improving photosynthetic efficiency and yield potential in wheat breeding.
