A total of 174 cereal-based food products, 67 compound feeds and 19 feed raw materials were analysed for the occurrence deoxynivalenol, 3-acetyldeoxynivalenol, 15-acetyldeoxynivalenol, zearalenone, α-zearalenol, β-zearalenol, their respective masked forms, including deoxynivalenol-3-glucoside, zearalenone-4-glucoside, α-zearalenol-4-glucoside, β-zearalenol-4-glucoside zearalenone-4-sulfate. Fibre-enriched bread, bran-enriched cornflakes, popcorn oatmeal collected in Belgian supermarkets from...
Aspergillus flavus is the main producer of carcinogenic aflatoxins in agricultural commodities such as maize. This fungus occurs naturally on crops, and produces when environmental conditions are favourable. The aim this study to analyse genetic variability among 109 A. isolates previously recovered from maize sampled a known aflatoxin-hotspot (Eastern region, Kenya) major maize-growing area Rift Valley (Kenya), determine their toxigenic potential. DNA analyses internal transcribed spacer...
Significance The regeneration of entire plants from explants is an important step in plant production and transformation protocols. Despite recent advances the knowledge on molecular basis regeneration, many aspects process causes recalcitrance are still poorly understood. We combined linkage with association mapping to find genes underlying natural variation shoot Arabidopsis . With this approach, we identified confirmed involvement RECEPTOR-LIKE PROTEIN KINASE1 as a previously unknown...
Fusarium graminearum can cause Giberella Ear Rot (GER) and seedling blight in maize, resulting major yield losses. Besides GER, the infected grains are consequently contaminated with multiple mycotoxins of F. graminearum. Zearalenone trichothecenes, such as deoxynivalenol its acetylated forms, among associated infection maize. In current work, we explored effect endophytic fungal genera Epicoccum Sordaria, to control comparative trials Piriformospora spp., an elusive genus. Furthermore,...
Mycotoxins are toxic metabolites of fungi that contaminate food and feed. These toxins can cause acute chronic health threats to both humans animals. In sub-Saharan Africa, exposure mycotoxins is under-reported. The study explores contamination grains (sorghum, maize, groundnut, millet) with four (aflatoxins, fumonisins, ochratoxins, deoxynivalenol) dietary quantify associated risks in northern Uganda. results underscored the high prevalence mycotoxins, only 7% samples were free from toxins....
Abstract Plant diseases are often caused by a consortium of pathogens competing with one another to gain foothold in the infection niche. Nevertheless, studies limited single pathogen on its host. In Europe, fusarium head blight (FHB) wheat is multiple Fusarium species, including graminearum and F. poae . Here, we combined time series (co)inoculations, monitored multispectral imaging, transcriptional, mycotoxin analyses, study temporal interaction between both species wheat. Our results...
Early blight of potato is caused by the fungal pathogen Alternaria solani and an increasing problem worldwide. The primary strategy to control disease applying fungicides such as succinate dehydrogenase inhibitors (SDHI). SDHI-resistant strains, showing reduced sensitivity treatments, appeared in Germany 2013, shortly after introduction SDHIs. Two mutations SDH complex (SdhB-H278Y SdhC-H134R) have been frequently found throughout Europe. How these resistances arose spread, whether they are...
Maize ear rot caused by several Fusarium species is an important fungal disease. Apart from yield losses, fungi can produce mycotoxins and masked forms in infected grains. Masked have received increased attention view of their bioavailability potential toxicity animals humans, but presence relevance the field still remain undisclosed. To get a better insight, present study assessed various parent mycotoxins, i.e. deoxynivalenol, 3-acetyldeoxynivalenol, 15-acetyldeoxynivalenol,...
Yield losses of crops due to plant pathogens are a major threat in all agricultural systems. In view environmental issues and legislative limitations for chemical crop protection products, the need design new environmentally friendly disease management strategies has gained interest. Despite unique capability green leaf volatiles (GLVs) suppress broad spectrum pathogens, their capacity control potato late-blight-causing agent Phytophthora infestans not been well studied. This study addresses...
Despite great efforts to forecast plant diseases, many of the existing systems often fall short in providing farmers with accurate predictions. One main problems arises from existence year and location effects, so that more advanced procedures are required for evaluating an unbiased manner. This paper illustrates case Fusarium head blight winter wheat Belgium. We present a new cross-validation strategy enables evaluation predictive performance forecasting system years locations different on...
Deoxynivalenol ( DON ) is one of the most prevalent toxins in Fusarium ‐infected wheat samples. Accurate forecasting systems that predict presence are useful to underpin decision making on application fungicides, identify fields under risk, and help minimize risk food feed contamination with . To this end, existing often adopt statistical regression models, which attempts made values as a continuous variable. In contrast, paper advocates use ordinal models for prediction values, by defining...
