Population-level gene copy number variations reveal distinct genetic properties of different Malus species.

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.
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
backgroundCopy number variations (CNVs) are crucial in plant evolution, adaptation, and domestication. In this study, we explored how CNVs contribute to genetic diversity, evolution, and adaptation during apple domestication. We examined the genome-wide CNV profiles and segmental duplications (SDs) in 116 Malus accessions, including domesticated apple (Malus domestica) and its primary progenitor species (M. sieversii and M. sylvestris).
resultsOn average, two accessions of the same species showed differences in at least 7,000 genes with varying copy number (CN) profiles. In contrast, accessions from different species had at least 20,000 genes with differing CN profiles. Notably, 700 genes exhibited distinct CN profiles between M. domestica and M. sieversii, with an enrichment in defense response genes. Genes related to fruit ripening, flavor, and anthocyanin biosynthesis had higher copy numbers in M. domestica. Additionally, 360 genes showed differential CN profiles between M. domestica and M. sylvestris, with enrichment in polygalacturonase activity, which may influence differences in fruit flavor. The study also identified 3,000 genes with significant CN differentiation (V
conclusionsThese findings offer valuable insights into the evolutionary mechanisms driving apple domestication and adaptation and provide a comprehensive resource for future research and apple breeding.
