Control effects and mechanisms of metabolites from Streptomyces ahygroscopicus var. gongzhulingensis strain 769 on sclerotinia rot in sunflowers

mycolabadmin

Scientists discovered that a beneficial soil bacterium called Streptomyces can effectively control sunflower rot disease caused by a harmful fungus. When applied to soil or roots, this bacterium reduced disease severity by over 50% and improved plant root health and seed quality. The treatment works by both directly killing the pathogenic fungus and strengthening the plant’s natural defense systems.

Recent Advances and Developments in Bacterial Endophyte Identification and Application: A 20-Year Landscape Review

mycolabadmin

Bacterial endophytes are beneficial bacteria living inside plants that help them grow stronger, resist diseases, and even clean up polluted soil. Scientists have studied these helpful microbes for 20 years and discovered they can be identified using both traditional laboratory methods and advanced DNA technologies. These bacteria show promise for making farming more sustainable by reducing the need for chemical pesticides and helping crops survive droughts and other stressors.

Providing a toolbox for genomic engineering of Trichoderma aggressivum

mycolabadmin

Scientists have created a set of tools to genetically engineer Trichoderma aggressivum, a fungus that causes green mold disease in cultivated mushrooms but can also be used beneficially. The study provides step-by-step methods for transforming this fungus using both traditional plasmid methods and modern CRISPR gene-editing technology. These tools will help researchers understand how the fungus works and potentially harness its beneficial properties for agriculture.

Antifungal and other bioactive properties of the volatilome of Streptomyces scabiei

mycolabadmin

Researchers discovered that Streptomyces scabiei, a bacterium known for causing common scab disease on potatoes and other root vegetables, produces various airborne chemicals with surprising benefits. Using advanced laboratory techniques, scientists identified 36 different volatile compounds from this bacterium, many of which can kill harmful fungi and potentially help plants grow better. While traditionally viewed as purely harmful, these findings suggest the bacterium may actually serve a more complex role in soil, sometimes protecting crops from more dangerous diseases.

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

mycolabadmin

Scientists discovered beneficial bacteria living on ash and pine trees that can fight two major forest diseases: ash dieback and needle cast. These bacteria not only kill the harmful fungi but also help trees grow stronger by improving nutrient absorption. This research offers promise for protecting European forests without relying on chemical fungicides, creating a more natural and sustainable approach to forest health.

Trichoderma brevicompactum 6311: Prevention and Control of Phytophthora capsici and Its Growth-Promoting Effect

mycolabadmin

Researchers isolated a beneficial fungus called Trichoderma brevicompactum from pepper plant soil that can fight a serious disease affecting peppers worldwide. This fungus not only kills the disease-causing pathogen but also helps pepper plants grow better. The study shows this fungus works through multiple mechanisms including wrapping around harmful fungi and producing growth-promoting compounds. This offers farmers an environmentally friendly alternative to chemical pesticides for protecting their pepper crops.

Eleven new species of Trichoderma (Hypocreaceae, Hypocreales) from China

mycolabadmin

Scientists discovered 11 new species of Trichoderma fungi in China that were isolated from soil and grass plants. These fungi are important because they can produce useful compounds, help control plant diseases, and promote plant growth. The researchers used genetic analysis and microscopy to identify and describe these new species, expanding our knowledge of fungal diversity in China.

Solid-state NMR spectroscopy reveals unique properties of Trichoderma harzianum cell wall components

mycolabadmin

Scientists used advanced spectroscopy techniques to examine the cell wall structure of Trichoderma harzianum, a beneficial fungus used to protect crops from harmful fungi. They discovered that this fungus has a uniquely organized cell wall composed of tough chitin layers inside and flexible sugar polymers outside. This special arrangement helps protect the fungus from dissolving itself with its own powerful enzymes while allowing it to attack pest fungi effectively.

Synergistic effects of beneficial microbial inoculants and SMS-amendments on improving soil properties and Pinus seedling growth in degraded soils

mycolabadmin

This study shows how mixing beneficial bacteria with mushroom waste can improve poor soil quality. The bacteria help break down the mushroom waste into nutrients that plants need, while also creating a healthier soil environment full of beneficial microbes. When this treated mushroom waste was added to degraded soil and used to grow pine seedlings, the plants grew taller with thicker stems and more leaves than in untreated soil. This approach offers a practical way to recycle agricultural waste while restoring damaged soils.

Acid Phosphatase Produced by Trichoderma harzianum in Solid Fermentation Using Millet

mycolabadmin

Researchers used a fungus called Trichoderma harzianum grown on millet grain to produce phosphatase enzymes, which help convert unavailable phosphorus in soil into forms that plants can use. By carefully controlling the amount of millet, moisture, and fungal starter culture, they achieved significantly higher enzyme production than previous methods. This inexpensive, sustainable approach could improve soil fertility and plant growth in agriculture.
