Summary: The disease Fusarium crown and root rot (FCRR) seriously affects tomato yields, but the genes and mechanism of resistance to FCRR are not well understood. The study shows that the LecRK gene SlLecRK1 plays a role in the immune response of tomato plants to FORL infection by triggering the expression of ERF genes.

Summary: This study analyzed transcriptome data of FCRR-resistant and susceptible tomato cultivars and identified differential gene expression and enriched gene families related to plant disease resistance. The findings provide valuable disease resistance resources for tomato breeding and genetic resources for the screening and cloning of FCRR resistance genes.

Summary: This study reveals that the FoMC69 gene in Fusarium oxysporum f. sp. radicis-lycopersici (Forl) is essential for virulence in tomato plants. FoMC69 gene is expressed at higher levels in Forl compared to F. oxysporum f. sp. lycopersici (Fol), and its knockout mutant shows reduced pathogenicity. Fluorescent labeling using WGA-FITC reveals morphological differences between Forl and its Delta FoMC69 mutant in the roots. The chlamydospore production of the Delta FoMC69 mutant is three times higher than that of the wild type.

Summary: Tomatoes are the most cultivated and important vegetable crop in the world, but they are susceptible to fusarium wilt disease. This study found that nanoemulsions obtained from extracts of Chilean medicinal plants can effectively inhibit the growth of fusarium wilt pathogens and provide good disease control at high concentrations.

Summary: UV-A radiation stimulates plants and can induce benefits through the production of bioactive compounds and secondary metabolites. This study evaluates the ability of UV-A radiation to enhance tolerance against Fusarium oxysporum f. sp. lycopersici (Fol) in tomato plants. The results show that UV-A radiation decreases Fol severity and prevents its negative effect on tomato plants, while increasing secondary metabolites and photosynthetic pigments.

Summary: This study evaluated the antifungal activity of marine-derived Firmicutes strains against the tomato phytopathogen Fusarium oxysporum f. sp. lycopersici (FOL), and identified Paenibacillus sp. PNM200 as a potential biocontrol agent. PNM200 colonized the tomato plant root system, increased plant growth, and reduced vascular wilt severity, showing potential as a biological control agent. The results suggest that marine-derived bacteria could be a new source of biological control agents for soil-borne diseases like Fusarium vascular wilt.

Summary: In this study, the volatilomes of Mentha spicata immobilized in vermiculite balls were found to effectively inhibit the mycelial growth of Fusarium oxysporum f. sp. lycopersici. The volatilomes of M. spicata traveling a certain distance from the center of the PVC chamber demonstrated the maximum reduction in colony growth. Tomato plants inoculated with Fusarium wilt pathogens showed increased expressions of defense genes and transcription factors after exposure to the volatilomes.

Summary: This study identified and annotated pathogenic carbohydrate-active enzymes (CAZymes) in the xylem sap of a susceptible tomato variety. The majority of the annotated CAZymes belonged to hydrolase and oxidoreductase families, with 90% of them being soluble and extracellular. Structural elucidation and molecular dynamics simulation provided insights into the structural characteristics and stability of these CAZyme families.

Summary: By comparing the pathogenicity chromosomes of Fusarium oxysporum f. sp. radicis-cucumerinum and F. oxysporum f. sp. melonis, researchers identified a candidate gene that may be responsible for the difference in host range between these two formae speciales.

Summary: Physiological race determination of 143 Fusarium oxysporum f. sp. lycopersici (FOL) isolates collected over 30 years in major tomato-producing regions of Brazil revealed the prevalence of race 3 isolates, indicating the emergence of novel FOL races or genetic variants. The study highlights the importance of developing novel race-specific marker systems for precise discrimination and suggests distinct evolutionary mechanisms are at play in selecting new FOL races across agroecosystems globally.

Summary: Fusarium oxysporum f. sp. lycopersici (Fol) is a major pathogen causing vascular wilt disease in tomato. It interferes and suppresses the host immune response by blocking transpirational pull, and induces secondary infection response through fungal invasion and colonization. Fasciclin-like proteins (FLPs) play important roles in the development and pathogenicity of Fol. By targeting FLPs using RNAi technology, the spore count and germination frequency can be significantly reduced, leading to a reduction in disease symptoms.

Summary: Pathogens use secreted effectors to manipulate plant defense. The study identified a secreted protein, FolAsp, belonging to the aspartic proteases family, in Fusarium oxysporum f. sp. lycopersici (Fol), which is upregulated and localized in the apoplast. FolAsp inhibits plant cell death and displays protease activity on host proteins, enhancing pathogen virulence.
