Sunlight-sensitive carbon dots for plant immunity priming and pathogen defence

mycolabadmin

Scientists developed special tiny carbon particles that respond to sunlight by producing molecules that strengthen plant defenses against fungi. When sprayed on plants like tomato and tobacco, these particles trigger the plant’s natural immune system, reducing fungal diseases by 12-44% without harming the plant. At higher concentrations with continuous sunlight, the particles can directly kill fungal pathogens. This eco-friendly approach offers a sustainable alternative to chemical fungicides while maintaining crop yields.

Tracking of Tobacco Mosaic Virus in Taxonomically Different Plant Fungi

mycolabadmin

Scientists discovered that a common plant virus (tobacco mosaic virus) can infect and multiply inside certain fungal pathogens that harm crops. When the virus enters these fungi, the fungi activate their natural defense system to fight back. Interestingly, the virus doesn’t make the fungi more or less dangerous to plants. This discovery opens new possibilities for controlling harmful fungi using viruses as biological tools.

Tracking of Tobacco Mosaic Virus in Taxonomically Different Plant Fungi

mycolabadmin

Scientists discovered that tobacco mosaic virus can infect and replicate inside some fungal pathogens like Botrytis and Verticillium, which are major crop diseases. Interestingly, when viruses infect these fungi, the fungi activate their own defense mechanisms to fight the virus, yet still maintain their ability to cause disease in plants. This discovery opens new possibilities for using plant viruses as tools to study and potentially control harmful fungal pathogens on crops.

Characterization of Fungal Pathogens Causing Blueberry Fruit Rot Disease in China

mycolabadmin

Researchers in China identified seven different fungi causing blueberry fruit rot disease from samples collected in Guizhou and Fujian provinces. Three of these fungi were found on blueberries for the first time. The study showed that blueberries can suffer from multiple fungal infections at once, both during growth and after harvest, causing significant crop losses. Understanding these different pathogens helps farmers develop better strategies to prevent and manage blueberry diseases.
