Summary: This study collected soybean seeds with serious symptoms of rotted pods from a farm in Hubei Province, China. Fusarium strains were isolated from the seeds and two Fusarium species were identified. The strains from the Fusarium fujikuroi species complex showed higher pathogenicity on soybean seeds, roots, and pods compared to the strains from the Fusarium incarnatum-equiseti species complex. F. proliferatum YZU 201408 was found to be the most pathogenic strain, causing disease severity of 72.2% to 90% in all tests.

Summary: This study identified a novel peroxisomal protein FgPEX22-like in Fusarium graminearum and demonstrated its crucial roles in sexual and asexual reproduction, fatty acid utilization, mycotoxin production, as well as pathogenicity. Additionally, FgPEX22-like also affects lipid droplet formation, reactive oxygen species elimination, and Woronin bodies biogenesis.

Summary: Plants have developed intricate defense mechanisms called innate immunity to protect against pathogens, with vesicular trafficking playing a crucial role in plant-pathogen interactions. This study found that components of the vesicular trafficking system involved in immunity in Arabidopsis also play a role in the interaction between wheat and the fungal pathogen Fusarium graminearum.

Summary: Recent studies have shown synergistic effects of the coexistence of the English grain aphid Sitobion avenae and phytopathogen Fusarium graminearum on wheat spikes. Understanding the relationship between wheat-aphids and wheat-pathogens has contributed to the understanding of these tripartite interactions at the ecological level. In addition, preexposure to the herbivore S. avenae triggers the accumulation of mycotoxins, stimulating the infection process of F. graminearum and the epidemic of Fusarium head blight (FHB) in agroecosystems.

Summary: Research in Brazil shows that Fusarium meridionale is more aggressive and competitive in causing maize Gibberella ear rot compared to Fusarium graminearum. This dominance of F. meridionale in Brazil may be attributed to its higher aggressiveness and competitiveness.

Summary: The study conducted a survey on the population, pathogenicity, and toxigenic chemotypes of Fusarium species associated with maize stalk rot in Yunnan Province, China. Twelve different Fusarium species were identified, each showing varying levels of aggressiveness in causing disease symptoms on maize stalks. This research will aid in designing an effective integrated control strategy for maize stalk rot in the region.

Summary: The study investigated the occurrence of FGSC in gramineous weeds near wheat fields in China, identifying Fusarium graminearum and Fusarium asiaticum as the dominant species. Different trichothecene genotypes and mycotoxins had varying effects on Fusarium head blight severity in wheat, highlighting the importance of weed management for reducing FHB inoculum.

Summary: In this study, it was found that autophagy inhibition and activation could reduce the pathogenicity and conidial yield of F. graminearum, while mitophagy did not seem to affect its pathogenicity. This provides a new perspective for managing plant fungal diseases caused by F. graminearum.

Summary: Fusarium head blight (FHB) and Gibberella ear and stalk rot (GER and GSR) are important diseases of wheat and maize worldwide. The dominant species causing FHB and GER/GSR in Brazil varies depending on host. Phenotypic differences between Fusarium graminearum and F. meridionale are relevant for pathogenicity and disease management.

Summary: Fusarium meridionale is more aggressive on maize compared to F. graminearum, which leads to its dominance in causing Gibberella ear rot and Gibberella stalk rot in Brazilian maize. The severity of ear rot is higher for F. meridionale isolates from maize compared to F. graminearum isolates, while the severity of stalk rot is slightly higher for F. graminearum isolates. Different mycotoxins are produced by the two species.

Summary: This study identified and characterized 14 PX domain-containing proteins in Fusarium graminearum, which play crucial roles in plant infection and mycotoxin production. These proteins exhibit distinct subcellular localizations and are essential for fungal development and pathogenicity. Of particular interest is FgBem1, which is indispensable for sexual development and virulence, highlighting the importance of PX domain in fungal pathogenicity.

Summary: By studying the components of the RNA exosome complex in the wheat fungal pathogen Fusarium graminearum, it was found that FgEXOSC1 and FgEXOSCA play important roles in vegetative growth, sexual reproduction, and pathogenicity. Deletion of FgEXOSC1 also resulted in abnormal toxisomes, decreased deoxynivalenol (DON) production, and downregulation of the expression levels of DON biosynthesis genes.

Summary: By investigating the functions of FgGyp1 in F. graminearum, it was found to play a critical role in the vegetative growth, conidiation, and virulence of the fungus, as well as negatively regulating DON biosynthesis. Additionally, FgGyp1 functions as a GTPase-activating protein for FgRab1 and is essential for the fusion of secretory vesicles from the Golgi with the plasma membrane in F. graminearum.

Summary: The research demonstrates the use of transgenic soybean lines expressing siRNA against the CYP51B gene from Fusarium oxysporum to improve resistance. Results showed the presence of siRNA in leaves and roots of transgenic lines, leading to resistance to F. oxysporum. Transgenic plants exhibited better growth and development when challenged with fungal pathogens.
