Geographic structure and human-mediated gene flow in driving genetic diversity of Heterodera glycines: A mitochondrial COI-based cross-regional analysis.
Article in Pest management science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe soybean cyst nematode (SCN, Heterodera glycines) is a major threat to Chinese soybean production. Understanding its spatial distribution and genetic dynamics is critical for developing sustainable management strategies.
resultsOur survey confirmed SCN presence in 15 of 19 sampled provinces, with high-density populations in Xinjiang and Inner Mongolia indicating expansion risks. Analysis of the mitochondrial COI gene of 44 Chinese populations revealed three distinct genetic groups: Northeast China, Huang-Huai-Hai region and Northwest China. This regional structure aligns with major soybean cultivation zones and host adaptation. Huang-Huai-Hai populations showed genetic homogeneity (centered on Hap3/Hap11) linked to uniform cultivation and Race 2 dominance. Northeast populations exhibited high heterogeneity owing to diversified physiological Races under selection from resistant varieties. Crucially, significant human-mediated gene flow (N
conclusionThese findings demonstrate that contemporary agricultural trade and practices drive SCN genetic architecture and dispersal more powerfully than geography, underpinning the need for region-specific management strategies that include careful monitoring and quarantine of imported crops. © 2026 Society of Chemical Industry.
