  "abstract": "Fusarium species are major contributors to Fusarium head blight (FHB) and mycotoxin contamination in cereal production. To characterize microbial co-occurrence associated with toxin accumulation in oats, the Fusarium, fungal, and bacterial communities of 51 Finnish oat grain samples were analyzed using a multi-marker metabarcoding approach targeting Fusarium translation elongation factor 1‑alpha (EF1α), fungal ITS2, and bacterial 16S regions. Microbial profiles were compared between grains with high and low deoxynivalenol (DON) concentrations. High‑DON samples were dominated by F. graminearum, whereas F. langsethiae prevailed in low‑DON grains. Bacterial diversity was higher in high‑DON samples, while fungal diversity remained similar across groups. Several bacterial genera, including Pseudomonas, Paenibacillus, Massilia, and Curtobacterium, exhibited negative correlations with Fusarium species, indicating competition in the same niche, whereas Duganella and Xylophilus showed positive association with Fusarium abundance. Microdochium consistently co-occurred with Fusarium. Results show differences in microbial communities associated with mycotoxin levels and Fusarium community composition, identifying taxa that may influence FHB or indicate mycotoxin risk.\n\nGraphical Abstract:\n\nSupplementary Information: The online version contains supplementary material available at https://doi.org/10.1007/s00248-026-02848-6.",
