A Cross-Domain Framework for the Dual Nature of Geotrichum and Magnusiomyces Across Plant, Food, and Clinical Systems.
Review in Current microbiology, 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
The arthroconidial yeast genera Geotrichum and Magnusiomyces exhibit a striking dual nature, simultaneously acting as destructive postharvest pathogens, essential agents in dairy fermentation, and life-threatening opportunistic pathogens in immunocompromised hosts. Despite extensive domain-specific research, the mechanistic basis of this functional divergence remains poorly integrated across taxonomy, plant pathology, food microbiology, and clinical mycology. This review proposes a cross-domain framework that integrates taxonomic uncertainty, conserved molecular mechanisms, ecological plasticity, and exposure dynamics to explain this functional divergence. Here, "cross-domain" is used in a non-taxonomic sense and refers to integration across disciplinary and ecological/application contexts-plant pathology, food and dairy microbiology, and clinical mycology-rather than to the formal biological taxonomic rank Domain. The functional versatility of these yeasts can be partly interpreted through the context-dependent deployment of broadly conserved fungal mechanisms-including cell wall-degrading enzymes, CYP51-mediated sterol metabolism, secreted proteins/effectors, and stress-response pathways-operating under contrasting ecological and selective pressures, rather than by fundamentally distinct biological systems. Critically, this framework distinguishes unidirectional exposure pathways linking agricultural, food, and clinical environments from bidirectional feedback systems that may contribute to the emergence and circulation of adaptive traits. Within this perspective, we identify three cross-domain connections: a putative antifungal resistance cycle driven by converging agricultural and clinical azole selection, a dairy-clinical interface shaped by host-associated transmission and strain recombination, and a diagnostic blind spot linked to cross-reactivity in fungal detection systems. These insights are translated into testable hypotheses on genome-based species delimitation, resistance evolution, and domestication stability, providing a structured research agenda for coordinated risk assessment and resistance management within a One Health framework.
