Transcriptomic changes in the PacC transcription factor deletion mutant of the plant pathogenic fungus Botrytis cinerea under acidic and neutral conditions

Gray mold is a common fungal disease affecting many plants, and it survives by adjusting to different pH levels in plant tissues. Scientists studied a specific protein called PacC that acts like a switch controlling which genes turn on or off based on acidity levels. By comparing normal fungi to mutants without this protein, researchers identified hundreds of genes that help the fungus adapt and cause disease, offering insights into how to potentially combat this agricultural problem.

Effects of Environmental and Nutritional Conditions on Mycelium Growth of Three Basidiomycota

Researchers tested how three types of edible and medicinal mushroom fungi grow on different substrate mixtures to develop better biodegradable materials for packaging and insulation. They found that substrates rich in cotton fibers combined with specific carbon dioxide levels produced the fastest and densest fungal growth. These findings help optimize the production of eco-friendly mushroom-based materials that could replace plastic and foam products while being fully compostable.

Impact of Oxalic Acid Consumption and pH on the In Vitro Biological Control of Oxalogenic Phytopathogen Sclerotinia sclerotiorum

This research shows how bacteria can protect crops from a destructive fungus called Sclerotinia sclerotiorum. While scientists previously thought the bacteria worked by eating the toxic acid produced by the fungus, this study reveals that the bacteria also make the environment more alkaline (less acidic), which the fungus cannot tolerate. The combination of both effects—consuming the acid and changing the pH—is what actually stops the fungus from growing and damaging crops.

Impact of Oxalic Acid Consumption and pH on the In Vitro Biological Control of Oxalogenic Phytopathogen Sclerotinia sclerotiorum

Scientists studied how bacteria that eat oxalic acid can control a destructive plant fungus called Sclerotinia sclerotiorum. The fungus produces oxalic acid to damage crops, but when special bacteria consume this acid, they change the soil pH to become more alkaline, which the fungus cannot tolerate. This research shows that pH changes are just as important as removing the acid itself for controlling this pathogenic fungus in agriculture.
