Shotgun metabarcoding was applied to decipher the microbial-terroir. The results of 60 soil samples showed that there were three dominant fungal phyla, Ascomycota 66.36% ± 15.26%, Basidiomycota 18.78% ± 14.90%, Mucoromycota 11.89% ± 8.99%, representing 97% of operational taxonomic units (OTUs). Mutual interactions between microbiota diversity and soil physicochemical parameters were revealed. Principal component analysis showed descriptive clustering patterns of microbial taxonomy and resistance gene profiles in the case of the four historic vineyards (Szent Tamás, Király, Betsek, Nyúlászó). Linear discriminant analysis effect size was performed, revealing pronounced shifts in community taxonomy based on soil physicochemical properties. Twelve clades exhibited the most significant shifts (LDA > 4.0), including the phyla Verrucomicrobia , Bacteroidetes , Chloroflexi , and Rokubacteria , the classes Acidobacteria , Deltaproteobacteria , Gemmatimonadetes , and Betaproteobacteria , the order Sphingomonadales , Hypomicrobiales , as well as the family Sphingomonadaceae and the genus Sphingomonas . Three out of the four historic vineyards exhibited the highest occurrences of the bacterial genus Bradyrhizobium , known for its positive influence on plant development and physiology through the secretion of steroid phytohormones. During ripening, the taxonomical composition of the soil fungal microbiota clustered into distinct groups depending on altitude, differences that were not reflected in bacteriomes. Network analyses were performed to unravel changes in fungal interactiomes when comparing postveraison and preharvest samples. In addition to the arbuscular mycorrhiza Glomeraceae , the families Mycosphaerellacae and Rhyzopodaceae and the class Agaricomycetes were found to have important roles in maintaining soil microbial community resilience. Functional metagenomics showed that the soil Na content stimulated several of the microbiota-related agrobiogeochemical cycles, such as nitrogen and sulphur metabolism; steroid, bisphenol, toluene, dioxin and atrazine degradation and the synthesis of folate.}, year = {2024}, eissn = {1932-6203}, orcid-numbers = {Szilágyi-Rácz, Anna Anita/0000-0003-3612-3574; Molnár, Krisztina/0000-0001-6203-6154; Rácz, Csaba/0000-0002-0307-6508; Dobos, Attila Csaba/0000-0001-7904-2155} } @CONFERENCE{MTMT:34447668, title = {Recent Results in Aflatoxin Research at the University of Debrecen}, url = {https://m2.mtmt.hu/api/publication/34447668}, author = {Pócsi, István and Murvai, Katalin and Horváth, Enikő and Bodnár , Veronika and Mondok, Ágnes and Adácsi, Cintia and Molnár, Krisztina and Dobos, Attila Csaba and Leiter, Éva Juliánna and Pfliegler, Valter Péter and Pusztahelyi, Tünde}, booktitle = {International Conference on New Horizons in Biotechnology ABSTRACT BOOK}, unique-id = {34447668}, year = {2023}, pages = {110}, orcid-numbers = {Molnár, Krisztina/0000-0001-6203-6154; Dobos, Attila Csaba/0000-0001-7904-2155; Pfliegler, Valter Péter/0000-0001-6723-4416; Pusztahelyi, Tünde/0000-0002-5495-6273} } @article{MTMT:34141829, title = {Mycotoxins in food chain-climate effect and elimination studies}, url = {https://m2.mtmt.hu/api/publication/34141829}, author = {Pusztahelyi, Tünde and Adácsi, Cintia and Kovács, Szilvia and Dobos, Attila Csaba and Pfliegler, Valter Péter and Madhavan Nampoothiri, K. and Pócsi, István}, journal-iso = {ACTA MICROBIOL IMMUNOL HUNG}, journal = {ACTA MICROBIOLOGICA ET IMMUNOLOGICA HUNGARICA}, volume = {70}, unique-id = {34141829}, issn = {1217-8950}, year = {2023}, eissn = {1588-2640}, pages = {77-78}, orcid-numbers = {Pusztahelyi, Tünde/0000-0002-5495-6273; Dobos, Attila Csaba/0000-0001-7904-2155; Pfliegler, Valter Péter/0000-0001-6723-4416} } @article{MTMT:33705114, title = {The Effect of Environmental Factors on Mould Counts and AFB1 Toxin Production by Aspergillus flavus in Maize}, url = {https://m2.mtmt.hu/api/publication/33705114}, author = {Molnár, Krisztina and Rácz, Csaba and Dövényi-Nagy, Tamás and Bakó, Károly István and Pusztahelyi, Tünde and Kovács, Szilvia and Adácsi, Cintia and Pócsi, István and Dobos, Attila Csaba}, doi = {10.3390/toxins15030227}, journal-iso = {TOXINS}, journal = {TOXINS}, volume = {15}, unique-id = {33705114}, issn = {2072-6651}, abstract = {The toxins produced by Aspergillus flavus can significantly inhibit the use of maize. As a result of climate change, toxin production is a problem not only in tropical and subtropical areas but in an increasing number of European countries, including Hungary. The effect of meteorological factors and irrigation on mould colonization and aflatoxin B1 (AFB1) mycotoxin production by A. flavus were investigated in natural conditions, as well as the inoculation with a toxigenic isolate in a complex field experiment for three years. As a result of irrigation, the occurrence of fungi increased, and toxin production decreased. The mould count of fungi and toxin accumulation showed differences during the examined growing seasons. The highest AFB1 content was found in 2021. The main environmental factors in predicting mould count were temperature (Tavg, Tmax ≥ 30 °C, Tmax ≥ 32 °C, Tmax ≥ 35 °C) and atmospheric drought (RHmin ≤ 40%). Toxin production was determined by extremely high daily maximum temperatures (Tmax ≥ 35 °C). At natural contamination, the effect of Tmax ≥ 35 °C on AFB1 was maximal (r = 0.560–0.569) in the R4 stage. In the case of artificial inoculation, correlations with environmental factors were stronger (r = 0.665–0.834) during the R2–R6 stages.}, year = {2023}, eissn = {2072-6651}, orcid-numbers = {Molnár, Krisztina/0000-0001-6203-6154; Rácz, Csaba/0000-0002-0307-6508; Pusztahelyi, Tünde/0000-0002-5495-6273; Dobos, Attila Csaba/0000-0001-7904-2155} } @{MTMT:33285495, title = {Biological control and elimination of mycotoxins in food and feed}, url = {https://m2.mtmt.hu/api/publication/33285495}, author = {Pusztahelyi, Tünde and Kovács, Szilvia and Adácsi, Cintia and Miklós, Ida and Dobos, Attila Csaba and Győri, Zoltán and Madhavan Nampoothiri, K. and Pócsi, István}, booktitle = {Biotechnology at the University of Debrecen: 2022 International Symposium : Abstract Book}, unique-id = {33285495}, year = {2022}, pages = {17}, orcid-numbers = {Pusztahelyi, Tünde/0000-0002-5495-6273; Miklós, Ida/0000-0002-7074-4019; Dobos, Attila Csaba/0000-0001-7904-2155} } @article{MTMT:32644330, title = {A Systematic Review of the Efficacy of Interventions to Control Aflatoxins in the Dairy Production Chain—Feed Production and Animal Feeding Interventions}, url = {https://m2.mtmt.hu/api/publication/32644330}, author = {Farkas, Zsuzsa and Országh, Erika and Engelhardt, Tekla and Csorba, Szilveszter and Kerekes, Kata and Zentai, Andrea and Süth, Miklós and Nagy, A and Miklós, Gabriella and Molnár, Krisztina and Rácz, Csaba and Dövényi-Nagy, Tamás and Ambrus, Árpád and Győri, Zoltán and Dobos, Attila Csaba and Pusztahelyi, Tünde and Pócsi, István and Józwiak, Ákos Bernard}, doi = {10.3390/toxins14020115}, journal-iso = {TOXINS}, journal = {TOXINS}, volume = {14}, unique-id = {32644330}, issn = {2072-6651}, year = {2022}, eissn = {2072-6651}, orcid-numbers = {Csorba, Szilveszter/0000-0002-2238-4469; Molnár, Krisztina/0000-0001-6203-6154; Rácz, Csaba/0000-0002-0307-6508; Dobos, Attila Csaba/0000-0001-7904-2155; Pusztahelyi, Tünde/0000-0002-5495-6273} }
