Summary: This study evaluated a panel of 194 spring Synthetic Hexaploid Derived Wheat (SHDW) lines from CIMMYT for Fusarium head blight (FHB) resistance and identified significant phenotypic variation in disease incidence, severity, index, number of Fusarium Damaged Kernels (FDKs), and deoxynivalenol (DON) content. A Genome-Wide Association Study (GWAS) using a 90 K SNP chip array revealed 52 significant marker-trait associations for FHB resistance, including markers associated with DON content, FDKs percentage, FHB index, disease incidence, and disease severity. The identification of 395 candidate genes associated with FHB resistance suggests the potential of synthetic hexaploid wheat in enhancing diversity and introducing new sources of resistance against FHB.

Summary: In this study, 240 Chinese elite wheat cultivars and lines were evaluated for Fusarium seedling blight (FSB) resistance, with 23 accessions showing potential for FSB resistance breeding. Six stable quantitative trait loci (QTLs) were detected, with four KASP markers identified for marker-assisted selection. Analysis of defense-related genes revealed candidates for mapping QTLs, providing valuable resources for wheat breeding to enhance FSB resistance.

Summary: This study aimed to map quantitative trait loci (QTL) responsible for the expression of FHB resistance in two adapted cultivars and evaluate their co-localization with agronomic traits. It was found that FHB resistance QTL co-localized with QTL for plant height, days to heading, and days to maturity. Selecting for improved FHB resistance within adapted cultivars can be done by using markers associated with complementary QTL.

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 conducted a pot experiment with spring wheat to investigate the early detection of Fusarium head blight (FHB) and the efficacy of different biological control agents (BCAs). The results showed that hyperspectral imaging (HSI) could detect the pathogen nine days after inoculation, four days earlier than visual detection. Fungal BCAs demonstrated greater efficacy compared to bacterial ones. This research provides promising alternatives to reduce the use of chemical-synthetic plant protection products.

Summary: This study provides the first comprehensive landscape of Fusarium head blight-responsive RNA/DNA difference (RDD) in wheat, and investigates the effects of RDDs on RNA and protein sequences. The results show that RDDs may alter the mRNA and protein structures of genes and are correlated with FHB levels. This research is of great importance for a better understanding of the molecular basis underlying FHB resistance and the development of novel strategies to improve wheat FHB resistance through epigenetic methods.

Summary: The study identified four QTL for Fusarium head blight (FHB) resistance in a Brazilian spring wheat cultivar, Surpresa, with the largest effect QTL on chromosome 7A. A QTL for mycotoxin accumulation was also detected. These findings may diversify the FHB resistance gene pool and increase overall resistance to the disease 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: This study analyzed the genetic basis of adult plant resistance to stem rust in spring wheat line 'Copio'. The results showed that Copio carries multiple resistance genes that provide both race-specific and non-race-specific resistance to diverse races of stem rust fungus. These genes can be used in breeding programs to develop durable resistance in wheat.

Summary: The rise in atmospheric CO2 levels affects the nutritional integrity and disease resistance of wheat. Wheat cultivars with medium resistance to Fusarium Head Blight (FHB) are more affected by elevated CO2 levels compared to susceptible cultivars. The nutritional content and growth of the medium resistance cultivars show significant differences at elevated CO2 levels. This study highlights the importance of identifying wheat cultivars that can maintain nutritional integrity and FHB resistance under future atmospheric CO2 conditions.

Summary: This study investigated the FODMAP and ATI contents of 22 different wheat varieties and the effect of type I sourdough fermentation on these levels. The results showed that both variety and growing location significantly influenced the levels of FODMAPs and ATIs. Longer sourdough fermentation time resulted in reductions in fructans, raffinose, and ATIs, but a substantial increase in mannitol was observed.

Summary: This study demonstrates that wheat with the Fhb1 quantitative trait locus (QTL) provides reliable resistance to Fusarium head blight (FHB) at elevated CO2 levels. However, the presence of the Fhb1 QTL in more FHB-resistant wheat leads to increased disease spread and mycotoxin contamination.
