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

Although the mature wheat (Triticum aestivum L.) embryo constitutes only a small proportion of kernel weight, it plays a significant role in seed germination and seedling establishment. However, the genetic basis underlying wheat embryo size remains poorly understood. In this study, we measured the embryos of mature kernels from 199 recombinant inbred lines (RILs) across up to nine environments. Using linkage maps constructed with the Wheat 55 K SNP array, we identified genetic loci associated with embryo size, including embryo length (EL), embryo width (EW), embryo area (EA), and their respective ratios to kernel dimensions (EL/KL, EW/KW, and EL/EW). Nine stable quantitative trait loci (QTL) were detected within three co-located chromosomal intervals, six of which are likely novel. The major, stably expressed, and novel QTL-QEL.sicau-2CN-2D.1 and QEW.sicau-2CN-2D-were successfully validated in a natural population comprising 165 Sichuan wheat cultivars and 57 Sichuan wheat landraces across two environments. By leveraging the genomic assemblies of the two parental genotypes, we identified candidate genes for this locus on chromosome 2D. Furthermore, significant correlations were observed between embryo size and early vigor, as well as kernel traits. Collectively, these findings provide critical insights into the genetic architecture of embryo size and facilitate the fine mapping and breeding applications of this promising locus.
