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: The epidemiology of Fusarium Head Blight (FHB) in spring barley was assessed in this study. Soil and spray inoculation were used to increase disease pressure and provoke genotypic differentiation. The evaluation of stable quantitative FHB resistance in barley genotypes was achieved through the quantification of fungal DNA contents and multiple Fusarium toxins. The study also identified the impact of weather conditions on fungal colonization in mature barley grain.

Summary: This study reveals the critical role of FgNls1 in the pathogenesis of F. graminearum and suggests that host-induced gene silencing targeting F. graminearum effectors is a promising approach to enhance resistance to Fusarium head blight (FHB) in wheat.

Summary: Research has shown that the mycoparasite Sphaerodes mycoparasitica has a significant impact on the protein and lipid regions, with a connection between carbohydrates and protein regions, involving potential phenolic compounds. Through FTIR analysis, SEM and CLSM observation of fungus-fungus interactions, and PCA analysis, early mycoparasitism can be effectively detected as a vital strategy against plant pathogens.

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 F. graminearum grows downward within infected wheat spikes and DON accumulation is largely confined to the colonized tissue. Additionally, F. graminearum was able to infect wheat kernels and cause mycotoxin contamination even when inoculated 25 days after anthesis.

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: Through studying 496 barley accessions, it was found that the UGT13248 gene plays a role in resistance to Fusarium head blight (FHB) by converting DON to D3G, a nontoxic form; two mutant alleles (T368I and H369Y) were identified that increase FHB severity and reduce D3G production.

Summary: Fusarium graminearum is the main pathogen of Fusarium head blight (FHB) in wheat, barley, and corn. This study found that putrescine, a wheat defense compound, can have a significant impact on the transcriptome of F. graminearum and induce the synthesis of DON. Gene ontology and KEGG enrichment analysis revealed the involvement of various metabolic pathways. Co-expression analysis identified key transcription factor genes that may play important roles in DON synthesis. These findings provide important insights into the molecular mechanisms underlying putrescine-induced DON synthesis and facilitate the study of FHB pathogenic mechanisms.

Summary: The study explored intraspecific and interspecific diversity between Phoenix theophrasti individuals from Turkey, Crete, Greece, and P. dactylifera specimens from Turkey using ISSR analysis. Results showed that intraspecific diversity ranged from 13.45% to 26.63% for P. theophrasti and geographic and genetic distances were positively correlated. STRUCTURE analysis classified populations into four clusters, supporting the differentiation between P. theophrasti and P. dactylifera as different species.

Summary: This study investigated the antifungal effects of myrcene, a plant-based compound, on Fusarium graminearum PH-1 and Fusarium culmorum FcUK99. The minimum inhibitory concentration (MIC) and half of MIC (MIC50) of myrcene against both strains were found to be 25 μg/mL and 12.5 μg/mL, respectively. MIC50 application significantly decreased cell viabilities and increased catalase (CAT) activity. Apoptosis-like process and cellular oxidative stress were observed. Genomic template stability (GTS) percentages and methylation polymorphism values were calculated. Myrcene caused epigenetic modifications in both genomes. MIC50 dose affected the expressions of certain genes, but did not change retrotransposon movement. This study demonstrated the potential of myrcene as an effective antifungal agent with morphological, genetic, epigenetic, and cellular alterations.

Summary: This study investigated the expression levels of Pks12, Gip6, and Gip7 genes and their effects on pigmentation in F. culmorum. The presence of these genes was confirmed and their expressions were examined at different time points. The study also demonstrated the relationship between gene expression and mycelium pigmentation, as well as the production of aurofusarin and rubrofusarin.

Summary: The phylogenetic relationship among Fusarium graminearum Schwabe isolates was studied using mitochondrial cox3 and rnl gene variations. DNA fragments were amplified from purified isolates and sequenced. Nucleotide polymorphisms were detected by alignment and a phylogenetic relationship was constructed using PAUP 4.0a. The results showed that Korean isolates were closely related to Turkish and Iranian isolates. The methodology can be extended to other fungal species.

Summary: Heterologous expression of plant-derived SNK-Z peptide in E. coli was successfully achieved, and its tertiary structure was determined. The most efficient production of the recombinant fusion peptide (GST/SNK-Z) was achieved by induction with 0.1 mM isopropyl β-D-1-thiogalactopyranoside at 32°C. The purified GST/SNK-Z protein with a molecular weight of 30.14 kDa yielded 6.5 mg/L, and the GST tags were removed using PreScission protease. The IC50 of GST/SNK-Z for Staphylococcus aureus was calculated as 12.07 μM.
