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

The genetic basis of wheat yield is highly complex, being collectively influenced by key traits such as plant morphology, spike structure, and grain morphology. Therefore, exploring the genetic regulatory mechanisms underlying yield-related traits is crucial for breeding high-yield wheat varieties. In the present study, a panel of 372 wheat landraces from Gansu province, China, was phenotyped four yield-related traits: spike length (SL), spikelet number per spike (SNS), grain number per spike (GNS), and thousand-kernel weight (TKW) over four years across five field environments at two locations (Qingshui and Lanzhou) in Gansu province. Genotyping was performed using a 16K SNP array, and genome-wide association studies (GWAS) were conducted on the multi-environment phenotypic data employing the Bayesian-information and Linkage-disequilibrium Iteratively Nested Keyway (BLINK), Compressed Mixed Linear Model (CMLM), Fixed and Random Model Circulating Probability Unification (FarmCPU), Mixed Linear Model (MLM) and Multi-Locus Mixed Model (MLMM) models. In total, we identified nine loci for SL, four loci for GNS, one loci for SNS, and five loci for TKW. The phenotypic variation explained (PVE) by these loci ranged from 2.0% to 22.0%. Each locus exhibits 2-4 haplotypes and showed significant differences between haplotypes. Furthermore, 16 candidate genes associated with panicle traits were predicted and they encoded proteins such as squamosa promoter-binding protein, F-box family protein, ferredoxin-NADP-oxidoreductase 2, aspartic proteinase Asp1, Pre-mRNA splicing factor and so on. These results provide novel genetic loci for wheat yield improvement, offering valuable resources for future breeding programs.
