Biocontrol of Cercospora leaf spot in sugar beet by a novel Bacillus velezensis KT27 strain: Enhanced antifungal activity and growth promotion in laboratory and field conditions

mycolabadmin

This research demonstrates that a beneficial bacteria called Bacillus velezensis KT27 can effectively control a common fungal disease in sugar beet crops. The bacteria fights the disease by producing natural antifungal compounds and can be further enhanced by exposure to inactivated fungal pathogens. Field trials showed the bacterial treatment provided disease protection almost as good as chemical fungicides while also promoting plant growth and increasing sugar beet yield by up to 15%.

Effect of Inoculation with Arbuscular Mycorrhizal Fungi (Rhizophagus irregularis BGC AH01) on the Soil Bacterial Community Assembly

mycolabadmin

This study examined how arbuscular mycorrhizal fungi (a beneficial fungus that partners with plant roots) influence soil bacteria communities over time. Researchers grew maize plants with and without this fungus and tracked bacterial changes over 90 days. They found that the fungus creates a more stable and diverse bacterial community that reaches equilibrium around 60 days, helping improve nutrient availability for plant growth.

Biocontrol Potential of Trichoderma Ghanense and Trichoderma Citrinoviride toward Pythium aphanidermatum

mycolabadmin

Researchers identified two native Trichoderma fungi species that can protect cucumber plants from a destructive soil disease caused by Pythium. In laboratory and greenhouse tests, these beneficial fungi blocked pathogen growth and significantly improved plant survival and growth compared to untreated plants. These findings suggest these natural fungi could replace harmful chemical fungicides for protecting cucumbers and other crops.

Tackling Conifer Needle Cast and Ash Dieback with Host-Derived Microbial Antagonists Exhibiting Plant Growth-Promoting Traits

mycolabadmin

Scientists discovered native bacteria from European ash and Scots pine trees that can fight two destructive forest diseases: ash dieback and needle cast. These bacteria not only inhibit the disease-causing fungi but also help trees grow better by improving nutrient uptake. This natural approach offers an eco-friendly alternative to fungicide sprays for protecting forests.

A bibliometric analysis of fungal volatile organic compounds

mycolabadmin

Fungi release distinctive smells made up of volatile compounds that help them communicate with plants, bacteria, and other organisms. These fungal smell chemicals have grown from being studied mainly in wine fermentation to being explored for helping crops grow better, fighting plant diseases naturally, and creating food flavors without chemicals. This research shows that understanding how fungi use these smell chemicals could lead to more sustainable farming practices and natural alternatives to harmful pesticides.

Genetic Characterisation of the Bacterial Microbiota Associating With a Strain of Epichloë Fungal Endophyte of Perennial Ryegrass and the Interaction With Its Paenibacillus Members

mycolabadmin

Researchers discovered that cultures of a fungal endophyte found in perennial ryegrass contain complex bacterial communities dominated by Paenibacillus bacteria. These bacterial cells live on the surface of fungal filaments and regulate each other’s populations through antagonistic interactions, with one strain (E300) acting as a keystone species that controls the community structure. Despite these dynamic bacterial changes, the fungal host’s growth remained unaffected, suggesting a balanced symbiotic relationship important for the grass’s agricultural performance.

Providing a toolbox for genomic engineering of Trichoderma aggressivum

mycolabadmin

Scientists have developed a set of techniques to genetically modify the fungus Trichoderma aggressivum, which is usually known for ruining mushroom crops. This genetic toolkit allows researchers to edit genes in this fungus to study how it produces various compounds and why it affects mushrooms. By using modern gene-editing technology called CRISPR, researchers can now create specific mutations and study the fungus’s useful properties, such as its potential to protect crops or promote plant growth.

Diversity and functions of fungal VOCs with special reference to the multiple bioactivities of the mushroom alcohol

mycolabadmin

Fungi release various volatile compounds (VOCs) that have different effects on organisms and the environment. The most notable fungal VOC is 1-octen-3-ol, also called mushroom alcohol, which gives mushrooms their distinctive smell. This compound can inhibit fungal growth, repel insects, and help control plant diseases, but at high concentrations it may be toxic to humans and trigger immune responses. Scientists use fruit flies as a model to study how these fungal compounds affect health.

Endophytic Diversity in Sicilian Olive Trees: Identifying Optimal Conditions for a Functional Microbial Collection

mycolabadmin

Researchers studied beneficial bacteria and fungi living inside olive trees from Sicily to create a collection of microorganisms that could improve olive farming. They found that wild olive trees and samples collected in winter had the most diverse and beneficial microbes, and that organic farming practices supported greater microbial diversity. Some of these microbes, especially Bacillus bacteria, showed promise in fighting fungal diseases and promoting plant growth, offering potential for developing natural fertilizers and disease control methods.

Optimized production and characterization of red dye from Talaromyces purpureogenus PH7 for application as a textile dye

mycolabadmin

Researchers optimized conditions to produce natural red dye from a fungus called Talaromyces purpureogenus, which could replace harmful synthetic dyes in the textile industry. The dye successfully colored cotton fabrics and resisted fading from washing and sunlight exposure. The fungus also produces beneficial compounds that could improve soil health, making this an environmentally friendly alternative to petroleum-based chemical dyes.
