Evaluation of electrolyzed water to control fungal trunk pathogens in grapevine nurseries

mycolabadmin

Scientists tested a new disinfection treatment called electrolyzed water on grapevine nursery plants to prevent fungal infections. The treatment uses a simple process of mixing water, salt, and electricity to create a natural disinfectant. Tests showed the treatment effectively reduced fungal infections in young grapevines without harming the plants, offering grape growers a promising new way to protect their nursery stock.

Toxicity of Volatile Organic Compounds Produced by Pathogens Ewingella americana and Cedecea neteri Associated with Pleurotus pulmonarius

mycolabadmin

Researchers discovered that two types of bacteria (Ewingella americana and Cedecea neteri) causing diseases in oyster mushrooms (Pleurotus pulmonarius) produce harmful volatile compounds. These airborne toxins, especially one called 2,4-di-tert-butylphenol, can damage mushroom tissue and stop mushroom growth at very low concentrations. This is the first study showing that these bacterial volatiles are important factors in mushroom disease, which could help farmers develop better ways to detect and prevent these infections.

A GDP-mannose-1-phosphate guanylyltransferase as a potential HIGS target against Sclerotinia sclerotiorum

mycolabadmin

Scientists identified a critical fungal protein called SsMPG2 that helps the plant disease-causing fungus Sclerotinia sclerotiorum infect crops and survive. When this protein is silenced using genetic engineering techniques, plants become resistant to the fungus. The research shows this protein is important in many plant-pathogenic fungi, making it a promising target for developing disease-resistant crops through genetic modification.

Genome Sequencing of Cladobotryum protrusum Provides Insights into the Evolution and Pathogenic Mechanisms of the Cobweb Disease Pathogen on Cultivated Mushroom

mycolabadmin

Researchers sequenced the complete genome of Cladobotryum protrusum, a fungus that causes cobweb disease on cultivated mushrooms. This genome contains genes for producing toxins and enzymes that help the fungus attack and digest mushroom cells. Understanding this genetic blueprint could help farmers develop better strategies to control this disease and protect their mushroom crops from significant economic losses.
