Development of Green Fluorescent Protein-Tagged Strains of Fusarium acuminatum via PEG-Mediated Genetic Transformation

mycolabadmin

Scientists developed a method to genetically modify a harmful fungus called Fusarium acuminatum that causes root rot in plants like carnations. Using a technique that breaks down the fungal cell wall and uses a special chemical (PEG) to insert genes, they successfully added a green-glowing protein (GFP) marker to the fungus. This allows researchers to track where and how the fungus infects plants. The modified fungus still behaves normally, making it a useful tool for identifying which genes make the fungus dangerous, potentially leading to better disease control methods.

Impact of Various Essential Oils on the Development of Pathogens of the Fusarium Genus and on Health and Germination Parameters of Winter Wheat and Maize

mycolabadmin

Researchers tested four plant-based essential oils as natural alternatives to chemical fungicides for protecting wheat and maize seeds from harmful Fusarium fungi. Thyme oil proved most effective at preventing fungal infections and seedling disease, performing as well as synthetic fungicides. However, thyme oil at higher doses harmed seed germination and plant growth, suggesting careful dose selection is needed for practical use. The findings indicate essential oils could replace chemical pesticides while maintaining crop safety, though different oils must be tested for various crops.
