Summary: A screening trial for banana cultivars in Australia showed that several cultivars displayed considerable resistance to Fusarium oxysporum f.sp. cubense, the causal agent of Panama disease, particularly those from FHIA, TBRI, Indonesia, and Australia. This offers potential new options for controlling the spread of the disease.

Summary: This study identified plant toxins closely related to banana wilt caused by a Foc race 2 strain, with the characterization of non-specific phytotoxins such as fusaric acid, beauvericin, and enniatin A. Additionally, a specific protein fraction from a 29-day-old culture filtrate was found to protect leaves of a resistant banana cultivar from damage caused by these phytotoxic metabolites.

Summary: This study investigated the biological function of milRNAs in the fungal pathogen Foc. The results showed that milRNA biosynthesis is involved in Foc pathogenesis, with the FoQDE2 gene playing a crucial role. The milRNA milR-87 was identified as a key virulence factor, and its target gene FOIG_15013 was found to be responsible for the phenotypic changes observed in the milR-87 deletion mutant. The study highlights the importance of milRNAs in fungal diseases and suggests a potential strategy for combatting them.

Summary: This study found that Fusarium oxysporum f. sp cubense (Foc) spores can survive in water for more than 120 days, with reduced viability in stagnant water. It was recommended to extract and treat surface water before irrigation, as all water treatments were less effective in the presence of soil. Using peracetic acid to treat Foc-contaminated water is safe and cost-effective, while ozone and chlorine may have drawbacks. UV treatment would require high doses and is impractical for field application.

Summary: We developed and validated a novel and highly specific PCR and LAMP assay for detecting the Indian Foc race 1 based on a putative effector gene uniquely present in its genome. These assays were simple, fast, sensitive and specific, and could be explored for other Foc races.

Summary: In this study, a novel effector protein FoCupin1 from Foc TR4 was characterized, and its pivotal role in Foc TR4 pathogenicity was revealed. FoCupin1 was able to suppress cell death and downregulate defense-related gene expression, while had no effect on Foc TR4 growth and conidiation. These findings deepen our understanding of effector-mediated Foc TR4 pathogenesis.

Summary: We developed a LAMP method to detect the causal agent of fusarium wilt in oil palm, FOE. The method successfully detected FOE DNA from oil palm root tissues and could be used for FOE detection in nurseries and as a biosecurity tool for screening oil palm germplasm.

Summary: This study identified phosphomannose isomerase (Focpmi1) as a key enzyme involved in the biosynthesis of GDP mannose in the Foc TR4 genome. A mutant deficient in Focpmi1 was unable to grow without exogenous mannose and showed impaired growth under stress conditions. Focpmi1 was also found to be crucial for Foc TR4 infection and virulence.

Summary: Fusarium wilt of banana caused by Fusarium oxysporum f. sp. cubense is a devastating fungal disease in the banana industry. This study analyzed the proteomic data of resistant and susceptible banana varieties to Foc4, revealing differences in protein accumulation profiles and related functional modules. Understanding the resistance mechanism and identifying resistance-related genes in banana variety improvement are of great significance.

Summary: In this study, a strain of Streptomyces, named XY006, was found to have strong inhibitory activity against Fusarium oxysporum causing banana wilt disease. Two cyclic lipopeptide homologs, lipopeptin A and lipopeptin B, were identified as the corresponding antifungal metabolites. Pot experiments showed that XY006 successfully colonized banana plantlets and suppressed the incidence of banana wilt disease. Furthermore, XY006 fermentation culture application improved plant growth parameters and induced peroxidase activity, indicating a potential role in inducing resistance.

Summary: The study found that herbicide treatment accelerates colonization and sporulation of the fungus on banana tissue, while fungicide treatment does not prevent sporulation. Therefore, herbicide-treated plants may serve as a potential inoculum source for infecting nearby plants.

Summary: Fusarium oxysporum f. sp. cubense Tropical Race 4 (Foc TR4) is a pathogenic fungus causing Fusarium wilt in banana plants. It is highly destructive to commercial banana varieties and belongs to a clonal lineage within the Fusarium oxysporum Species Complex. Uncertainty exists regarding its host range, but it is considered a potential Union quarantine pest in the EU. Effective quarantine measures are crucial to prevent its spread and protect the European banana production areas.
