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

backgroundPopulus deltoides is a valuable timber species of considerable importance in the study of forest genetic breeding. However, its genetic improvement continues to rely predominantly on conventional selection and hybridization strategies hampered by long breeding cycles and limited efficiency.

resultsA total of 209 P. deltoides accessions were genotyped using a 60K SNP (Single nucleotide polymorphism) liquid array. Following quality control, 46,031 high-quality SNPs were screened and analyzed alongside 15 phenotypic traits in a genome-wide association study (GWAS), which identified 219 SNPs significantly associated with the traits. After further screening and annotation, a final set of 57 target SNPs and 77 candidate genes was obtained. Using kompetitive allele-specific PCR (KASP) assays, we successfully developed 48 polymorphic KASP markers. Of these, 25 markers exhibited significant phenotypic differences (p < 0.05) across genotype groups.

conclusionsThese 25 KASP markers can serve as reliable and practical tools for phenotype-assisted selection, providing efficient molecular resources for accelerating genetic improvement and marker-assisted breeding in poplar.
