Diversity, Ecological Characteristics and Identification of Some Problematic Phytopathogenic Fusarium in Soil: A Review

Diversity, Journal Year: 2023, Volume and Issue: 15(1), P. 49 - 49

Published: Jan. 1, 2023

The genus Fusarium includes many pathogenic species causing a wide range of plant diseases that lead to high economic losses. In this review, we describe how the taxonomy has changed with development microbiological methods. We specify ecological traits and methods its identification in soils, particularly detection phytopathogenic representatives mycotoxins produced by them. negative effects soil-borne on agricultural plants current for control are discussed. Due complexity polymorphism species, integrated approaches risk assessment necessary.

Microbial diversity in soils suppressive to Fusarium diseases

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 14

Published: Dec. 4, 2023

Fusarium species are cosmopolitan soil phytopathogens from the division Ascomycota , which produce mycotoxins and cause significant economic losses of crop plants. However, soils suppressive to diseases known occur, recent knowledge on microbial diversity in these has shed new lights phytoprotection effects. In this review, we synthesize current role their rhizosphere microbiota phytoprotection. This is an important issue, as disease does not develop significantly even though pathogenic susceptible host plant present, weather conditions suitable for disease. Soils documented different regions world. They contain biocontrol microorganisms, act by inducing plants’ resistance pathogen, competing with or inhibiting parasitizing pathogen. particular, some Bacillus Pseudomonas Paenibacillus Streptomyces involved protection diseases. Besides specific bacterial populations suppression, next-generation sequencing ecological networks have largely contributed understanding communities diseases, revealing community patterns differences a notable number taxa, according pathosystem, origin soil. Agricultural practices can influence suppressiveness influencing ecology. Research modes action should help guide development effective farming management sustainable agriculture.

Impact of bacterial and fungal inoculants on the resident rhizosphere microbiome and the volatilome of tomato plants under leaf herbivory stress

FEMS Microbiology Ecology, Journal Year: 2024, Volume and Issue: 100(2)

Published: Jan. 24, 2024

Various studies have addressed the impact of microbial inoculants on composition resident microbiome. How plant metabolism and interact with rhizobiota under herbivory stress remains elusive. Here, we investigated two bacterial fungal inoculants, inoculated as single species a synthetic community, rhizosphere microbiome volatilome tomato plants (Solanum lycopersicum) comparing nonstress conditions to exposed leaf by Spodoptera exigua. Based amplicon sequencing analysis, rhizobacterial community was significantly affected all four magnitude this effect dependent stress. Fungal altered but independent The impacted inoculation differences between treatments were evened Each inoculant caused unique changes in stressed also shared similar responses, particular enhanced production dimethyl disulfide benzothiazole. In conclusion, introduction well common volatilome, these minor compared induced

Bioprospecting of Novel Dye‐Tolerant Actinomycetes for the Fabric Dye degradation and Its Phytotoxicity Analysis

Environmental Quality Management, Journal Year: 2025, Volume and Issue: 34(4)

Published: March 19, 2025

ABSTRACT The current study aims to isolate novel dye‐tolerant actinomycetes from dye‐contaminated soil. antibacterial efficiency of the selected isolates (VITVR4 and VITVR6) displays highest inhibitory action against Pseudomonas aeruginosa (22 mm) considerable activity all other species. Both exhibit γ‐hemolysis, causing no pathogenicity in hemolytic activity. goal work is removal fabric azo dyes, including methyl orange (MO), Reactive blue‐19, Rhodamine B, by strains higher percentage decolorization MO, B VITVR4 observed as 86%, 79%, 74%, respectively. While VITVR6 exhibits dyes 72%, 80%, 88%, isolated were identified Microbacterium endophyticum (GenBank: OQ625846) Brevibacterium casei OQ625847) according phenotypic genotypic methods. Furthermore, phytotoxicity analysis microbially treated dye products indicated less toxicity Vigna radiata seeds. findings could potentially serve a useful tool for efficiently decolorizing released textile effluent

Clinical and Hospital Environmental Fusarium in Taiwan: Molecular Identification, Antifungal Susceptibilities, and Phylogenetic Analyses

Mycoses, Journal Year: 2025, Volume and Issue: 68(4)

Published: April 1, 2025

ABSTRACT Background Fusarium species are emerging pathogens known to cause both superficial and disseminated human infections. Aerosolized in healthcare settings have been associated with nosocomial fusariosis, particularly patients severe immunosuppression. Objectives To analyse the phylogenetic relationships of clinical hospital environmental isolates assess their susceptibility available antifungal agents. Methods Clinical were procured from four hospitals Taiwan, air water sampling collected at Kaohsiung Chang Gung Memorial Hospital (KCGMH). All identified through gene sequencing translation elongation factor 1‐α internal transcribed spacer regions ribosomal DNA. Antifungal testing followed CLSI M38‐A3 broth microdilution method. Results A total 41 4 identified, belonging five complexes (SC): F. solani SC (FSSC) (62.8%), fujikuroi (FFSC) (14.0%), incarnatum‐equiseti (11.6%), dimerum (7.0%), oxysporum (4.7%). Phylogenetic analysis revealed that KCGMH closely related samples same hospital. Amphotericin B exhibited high activity against most species. With exception FFSC, other demonstrated significantly elevated MIC values itraconazole, voriconazole, posaconazole, isavuconazole. Conclusions FSSC was prevalent exhibiting higher for azoles than FFSC isolates. The observed form clusters corresponding potential airborne infections environment cannot be overlooked.
