Banana Fusarium wilt caused by oxysporum f. sp. cubense (Foc TR4) is the most destructive soil-borne fungal disease. Until now, there has been a lack of effective measures to control It urgent explore biocontrol agents Foc TR4 and secretion mycotoxin. In this study, fluvirucin B6 was screened from Streptomyces solisilvae using an activity-guided method. Fluvirucin exhibited strong antifungal activity against (0.084 mM EC50 value) significantly inhibited mycelial growth spore germination. Further studies demonstrated that could cause functional loss mitochondria, disorder metabolism cells, decrease enzyme activities in tricarboxylic acid cycle electron transport chain, ultimately inhibiting mycotoxin metabolism. pot experiment, application decreased incidence banana amount controlled toxins soil. Additionally, positively regulate changes structure rhizosphere microbial community, enriching beneficial microbes associated with disease resistance. summary, study identifies B6, which plays versatile roles managing diseases mycotoxins.

UV-A radiation is a tool that has stimulant action in plants and can be used to induce benefits through the production of bioactive compounds synthesis secondary metabolites, among others. Particularly, its application could stimulate tolerance biotic stress caused by Fusarium oxysporum f. sp. lycopersici (Fol) tomato plants; for this reason, aim present study was evaluate ability against Fol. For this, crop established which two conditions supplementation with were tested on inoculated fungus The pathogen’s impact agronomic parameters, incidence severity, contents biomarkers, metabolites photosynthetic pigments determined. results show pathogen severity about 60%; therefore, fruit yield also negative (−31%). Moreover, significantly impacted content positive control increased H2O2 (+23.9%), malondialdehyde (+41.7%) proline (+54.8%). In contrast, decreased Fol (−35.5%), prevented effect plant/fruit yield. addition, biomarkers (−10.4% O2•−, −22% H2O2, −16% MDA), (+13.2% flavonoids, +35% anthocyanins) (+17% β-carotene, +12% yellow pigments, +19.8% total chlorophyll) pathogen.

Abstract Background: Fusarium wilt of banana, a soil-borne disease caused by Fusarium oxysporum (f.sp.) cubense, particularly the Tropical Race 4 (Foc TR4), severely hinders progress banana industry. Utilizing antagonistic microorganisms to suppress pathogen growth and enhance production is seen as promising strategy for management. Results: Strain XZ11-1, exhibiting highest siderophore ability, was isolated from Qixianling Rainforest in Hainan province, China. Through combination colony morphology, physiological biochemical analysis, well dual-gene analysis ITS4 TEF1, strain identified Trichoderma viride. Following optimization fermentation conditions, XZ11-1 produced siderophores with relative content 79.45%, both hydroxamate carboxylate-type siderophores. Additionally, demonstrated potent antifungal activity against 10 phytopathogenic fungi. Co-cultivation experiments revealed that under iron-limiting were primary factor inhibiting Foc TR4. Notably, exhibited stimulating effect on maize seed germination effectively colonized roots plants. Pot further viride could TR4 competing iron environment through mediation. Moreover, it absorption plants secreting bind Fe³⁺ environment. Conclusions: Therefore, high-yield represent valuable microbial resource controlling plant pathogenic fungi promoting growth.

ABSTRACT The soil-borne fungi Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4) causes banana wilt, which seriously threats global production. Biocontrol has been considered viable alternative method to manage wilt. In previous study, we found that novel S. luomodiensis SCA4-21 exhibited antifungal activity. Here, revealed the extracts of strain significantly inhibited growth Foc TR4 hyphae and spore germination, severely disrupting ultrastructure hyphal cells morphology. These also broad-spectrum activity against eight other phytopathogenic fungi. Furthermore, demonstrated produce 32 volatile organic compounds, including five compounds. a pot experiment, discovered inoculation infection in seedling corms, achieving biocontrol efficiency 59.3%, promoted seedlings. Additionally, this enhanced abundances beneficial bacterial genera Streptomyces , Bacillus Sphingomonas Massilia as well fungal Mortierella Purpureocillium Gibellulopsis Xenomyrothecium while reduced pathogenic bacteria genus Pantoea rhizosphere soil. Moreover, increased enrichment pathways such carbohydrate metabolism, amino acid metabolism terpenoids polyketides. Therefore, postulated may synergistically combat wilt by producing compounds enriching Our findings present promising agent for management IMPORTANCE Banana ( Musa spp.) is one most popular fruit crops fourth largest food crop developing countries within subtropical regions. However, emergence rapid spread hinder development industry. Currently, there no effective control measure available. Biological holds potential due its safety effectiveness. significant inhibitory effects on germination TR4, severe destructive cell morphology ultrastructure, We incidence index seedlings, enhances microbes metabolic pathways, suggesting agent.
