Summary: The endophytic fungus GG22 from Rehmannia glutinosa leaves was found to promote the growth and enhance the secondary metabolism of R. glutinosa. GG22 infection increased the activities of antioxidant enzymes, as well as the accumulation of NO and H2O2 signaling molecules. Additionally, the expression of enzyme genes related to secondary metabolites significantly increased after GG22 infection.

Summary: The antimicrobial activity of metabolites produced by Fusarium oxysporum PR-33 in submerged culture was evaluated, showing broad-spectrum antimicrobial action. The major compounds identified were fusarinolic acid and its isomer, dehydrofusaric acid, and fusaric acid, with fusaric acid responsible for the antimicrobial activity. The cytotoxicity of the extracts was also evaluated and showed potential as antimicrobial agents.

Summary: The present study demonstrates that two bacterial endophytes, Pseudomonas aeruginosa OS_12 and Aneurinibacillus aneurinilyticus OS_25, isolated from leaves of Ocimum sanctum Linn., promote plant growth and induce systemic resistance in pea plants against Fusarium oxysporum f.sp. pisi. These endophytes also showed antagonistic activity and produced various beneficial substances for plant growth. The pot trials revealed that pea plants treated with these endophytes had a lower infection rate of Fusarium root rot disease and improved growth parameters. The endophytes enhanced the activities of defense-related enzymes and reduced oxidative stress in the host plants.

Summary: This study reported for the first time the isolation of salt-tolerant Trichoderma atroviride from a marine habitat, showing antagonistic activity against Fusarium oxysporum causing cucumber root rot. The results demonstrated that the application of Trichoderma could alleviate the adverse effects of salt stress on cucumber and promote its growth, especially for the roots.

Summary: This study tested the ability of six plant endophytic bacteria to control Fusarium oxysporum and promote tomato plant growth. The bacteria showed activity in hydrolytic enzymes, hydrogen cyanide, indole 3-acetic acid, and siderophores. Application of the bacteria to tomato seeds prolonged incubation time of F. oxysporum, reduced disease incidence, and promoted plant growth.

Summary: In this study, an endophytic bacterium strain hg18, identified as Paenibacillus polymyxa, was found to inhibit the mycelial development of Fusarium oxysporum f. sp. cucumerinum, the causal agent of cucumber Fusarium wilt. Strain hg18 exhibited strong antimicrobial activity and promoted cucumber growth in greenhouse experiments.

Summary: This study isolated novel fungal strains from green manure-incorporated soils and analyzed the functions of volatile organic compounds (VOCs) produced by them. The results showed that the VOCs released by these fungi can promote the growth and development of Lactuca sativa and inhibit the growth of Fusarium oxysporum.

Summary: This study aimed to determine the efficacy of the soil yeasts Papiliotrema laurentii S-08 and Saitozyma podzolica S-77 for plant growth promotion and biocontrol of wilt disease in brinjal plants. The results showed that both yeast isolates demonstrated some plant growth promotion attributes as well as inhibited the growth of the phytopathogen. Applying these yeasts, individually or in consortium, significantly decreased the disease incidence in brinjal seedlings while enhancing their growth parameters.

Summary: The study revealed a fungistatic effect of the essential oil of P. auritum on Fusarium spp., which may be attributed to the presence of eugenol and thymol/p-cimen-8-ol in the oil. The antifungal activity was evaluated through direct contact and poisoned food tests, with the oil showing inhibition over 40% on Fusarium spp. at certain concentrations. Additionally, DART-MS chemical analysis identified key metabolites with high relative intensity in the oil.

Summary: The study focused on isolating endophytic fungi from wheat plants that can promote wheat growth and inhibit the growth of Avena fatua, a common weed. A strain of Fusarium oxisporum, identified as GW, was found to release compounds that hindered the growth of A. fatua while not affecting wheat seedlings. Additionally, the presence of this fungi in the soil reduced weed growth and enhanced wheat growth. The differential response of the two plants could be attributed to their contrasting physiological and biochemical status.

Summary: This study investigated the effects of Fusarium mycotoxins on wheat metabolism, revealing that plants exhibit a local defense response when exposed to toxins, potentially triggered by eavesdropping on the presence of the fungus. The research suggests that mycotoxins may initiate a plant defense mechanism and operate on multiple organs in response to fungal presence.

Summary: Banana Fusarium wilt caused by Fusarium oxysporum TR4 is a destructive soil-borne fungal disease. Actinomycetes from rhizosphere soil of Machilus pingii in Hainan province demonstrated significant antifungal activity, with strain BITDG-11 showing the strongest inhibition and broad-spectrum activity. Streptomyces BITDG-11 has the potential to become a novel species with strong antifungal activity and biocontrol capabilities.

Summary: In this study, we investigated the biological and genomic characteristics of two pathogenic fungi, Fusarium oxysporum (strain QK8) and F. solani (strain SX13), which cause brown rot disease in Gastrodia elata crops. We found their optimal growth conditions and conducted indoor tests to evaluate their virulence. Moreover, we assembled and analyzed the genomes of these two strains and compared them with existing data. These findings lay the groundwork for further research on G. elata brown rot disease.
