Summary: This study reveals that the deletion of membrane-bound transporters in the plant pathogenic fungus Fusarium graminearum leads to reduced accumulation of the mycotoxin deoxynivalenol (DON) and decreased disease symptoms on wheat. The ATP-binding cassette (ABC) transporter gene Abc1 plays a major role in DON accumulation and virulence reduction. Heterologous expression of F. graminearum transporters in yeast confirms Abc1 as a major mechanism of DON resistance and suggests the involvement of multiple transporters in resistance to other compounds. These findings provide valuable insights for developing novel management techniques for Fusarium head blight and other destructive plant diseases.

Summary: Modern spelt varieties with reduced plant height showed higher susceptibility to Fusarium head blight and higher contamination of grains with deoxynivalenol (DON), while old landraces and varieties had higher resistance and lower mycotoxin levels. These findings can aid in selecting suitable parental material for breeding spelt with improved FHB resistance.

Summary: The study found that Brazilian wheat exhibits varying degrees of resistance to Fusarium head blight, controlled by multiple genetic loci, with two major QTL identified on chromosomes 4B and 6B showing significant associations with disease-related traits. These findings provide new genetic resources for improving wheat quality and reducing the reliance on fungicides.

Summary: The study identified multiple fungal species contaminating wild rice, with Fusarium, Nigrospora, and Cladosporium being the most frequent genera. The research found that the Fusarium incarnatum-equiseti species complex (FIESC) was the main source of ZEN contamination in wild rice, with high levels of ZEN likely playing a key adaptive role. High levels of ZEN in the rice samples raised significant safety concerns regarding wild rice consumption by humans and animals.

Summary: Through comparing different agronomic and FHB management practices used in 1996 and 2016, this study found that modern management strategies including the use of moderately resistant cultivars, a fungicide applied at flowering, and high rates of N fertilizer were more effective in reducing FHB and improving agronomic performance compared to standard practices recommended in 1996.

Summary: This article reveals the changing threat of Fusarium head blight mycotoxins in European wheat over a period of ten years. The data shows persistent high levels of contamination, both in terms of single- and multi-mycotoxin contamination, as well as changing temporal-geographical distributions. This highlights the potential negative health consequences and economic costs of altering FHB disease pressure and pathogen populations.

Summary: This study used selected yeast strains to reduce the levels of mycotoxins produced by Fusarium culmorum, F. graminearum, and F. poae on wheat grain and bread. The results showed that these yeast isolates can be efficient mycotoxin decontamination agents in the food industry.

Summary: This study investigates the mechanisms by which the wheat NAC transcription factor TaNACL-D1 enhances resistance to Fusarium head blight. Transcriptomic analysis reveals that TaNACL-D1 overexpression leads to enhanced gene expression involved in detoxification, immune responses, secondary metabolism, hormone biosynthesis, and signaling. The findings provide insights into the mode of action and downstream target pathways for this novel NAC transcription factor, validating its potential as a gene to enhance FHB resistance in wheat.

Summary: This study evaluated the aggressiveness of F. cerealis to durum wheat cultivars and mycotoxin production in planta, finding that all cultivars exhibited typical FHB symptoms and NIV was the most produced mycotoxin. Molecular analysis revealed all strains possessed NIV genotype, while chemical assessment showed they could produce various secondary metabolites. The increasing incidence of F. cerealis and the potential crop contamination with mycotoxins pose great concern for food security and world cereal trade, especially given the higher toxicity of NIV compared to DON.

Summary: Fusarium head blight (FHB) is a destructive wheat disease causing yield losses and mycotoxin contamination in crop. Study shows strong correlation between resistance against multiple Fusarium species, mycotoxin contents, FHB severity and FHB-associated traits. Indirect phenotypic and genomic selection, using low anther retention and evaluating pre-selected genotypes in disease nurseries, is suggested as a suitable strategy for breeding wheat cultivars with reduced risk of mycotoxin accumulation.

Summary: This study investigated the changes in miRNA expression induced by DON in porcine liver, jejunum, and serum. The serum miRNA response to DON increased over time and declined after removal of contaminated diets. Receiver operating curve analyses for individual miRNAs were significant, and a combination of four miRNAs increased the predictive capacity for DON exposure.

Summary: Most farmers are willing to adjust their current agronomic management based on incentives, especially when wheat contains low levels of mycotoxins and free testing for mycotoxin presence. The most effective incentive varies depending on farm and farmer characteristics, such as country, crop type, size of arable land, soil type, education, and mycotoxin knowledge.
