Fungal Argonaute proteins act in bidirectional cross-kingdom RNA interference during plant infection

mycolabadmin

Scientists discovered that fungi and plants exchange genetic instructions called small RNAs to control each other during infection. A fungal pathogen called Botrytis cinerea uses special proteins called Argonautes to deliver these instructions into plant cells, which helps the fungus cause disease. Plants also send back their own genetic instructions to defend themselves. Understanding these molecular communications could lead to new ways to protect crops from fungal diseases.

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.

Unveiling microRNA-like small RNAs implicated in the initial infection of Fusarium oxysporum f. sp. cubense through small RNA sequencing

mycolabadmin

Researchers discovered specific small RNA molecules produced by the fungus that causes banana wilt disease. These molecular signals, particularly one called milR106, are critical for the fungus’s ability to infect and damage banana plants. By understanding how these molecules work, scientists can develop better strategies to protect banana crops from this devastating disease that threatens global banana production.

Argonaute1-Dependent LtmilR2 Negatively Regulated Infection of Lasiodiplodia theobromae by Targeting a Guanine Nucleotide Exchange Factor in RAS Signalling

mycolabadmin

Scientists discovered a tiny regulatory RNA molecule called LtmilR2 in a fungus that causes grape disease. This molecule naturally suppresses the fungus’s ability to cause infection by shutting down a gene called LtRASGEF. When researchers delivered LtmilR2 using specially designed nanoparticles, it successfully stopped the fungus from growing. This discovery could lead to a new type of biological fungicide for protecting grapes and vineyards.

Argonaute1-Dependent LtmilR2 Negatively Regulated Infection of Lasiodiplodia theobromae by Targeting a Guanine Nucleotide Exchange Factor in RAS Signalling

mycolabadmin

Scientists discovered a small RNA molecule called LtmilR2 in a fungus that causes grape canker disease. This molecule naturally suppresses the fungus’s ability to infect grapes. By delivering this molecule or similar RNA duplexes to the fungus, researchers were able to inhibit its growth and infection, suggesting a new type of biological fungicide that could protect vineyards without chemical pesticides.
