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

key messageThis study identified and validated novel QTL controlling flag leaf morphology, and predicted the underlying candidate genes with tissue-specific expression, offering valuable insights for improving plant architecture and grain yield. Flag leaf morphology (FLM) is a critical determinant of wheat yield, primarily due to its role in enhancing photosynthetic efficiency during the grain-filling stage. To elucidate the genetic basis underlying FLM, we evaluated 220 accessions of Sichuan Wheat using a 55 K SNP array combined with genome-wide association studies (GWAS). Four key traits, including flag leaf length (FLL), flag leaf width (FLW), flag leaf area (FLA), and flag leaf ratio (FLR), were assessed across four environments. GWAS identified seven quantitative trait loci (QTL) significantly associated with these traits. Notably, six of the loci, one for FLL and five for FLR, are potentially novel, with five validated in an independent natural population. Among identified QTL, QFLL.sicau.7D and QFLW.sicau.2B exhibited strong pleiotropic effects on all the traits studied. The T allele of QFLL.sicau.7D (AX-89737284; T/C) was associated with an increase in both FLL and plant height, suggesting a role in shoot architecture regulation. Furthermore, six candidate genes were identified within the novel QTL regions, based on elevated expression in flag leaf tissue and known involvement in developmental processes. These findings advance our understanding of the genetic architecture of FLM in Chinese wheat and provide valuable targets for fine-mapping and marker-assisted selection to improve yield and plant architecture.
