Changes of Active Substances in Ganoderma lucidum during Different Growth Periods and Analysis of Their Molecular Mechanism

mycolabadmin

Scientists studied how the medicinal mushroom Ganoderma lucidum changes as it grows, discovering that different growth stages contain different beneficial compounds. The budding stage was found to have the highest levels of powerful healing compounds called triterpenoids and steroids. This research helps identify the best time to harvest the mushroom to get maximum health benefits, improving both quality and standardized production for medicinal use.

Functions of the Three Common Fungal Extracellular Membrane (CFEM) Domain-Containing Genes of Arthrobotrys flagrans in the Process of Nematode Trapping

Researchers studied how a fungus called Arthrobotrys flagrans catches and kills parasitic worms. They found that three genes containing a special protein domain called CFEM control how the fungus produces sticky traps and deadly proteins. By studying mutant fungi with these genes deleted or overexpressed, they discovered that these genes work together and can compensate for each other, helping explain how this fungus could be used as a natural pest control for harmful nematodes.

Researchers studied three genes (CFEM1-3) in a fungus called Arthrobotrys flagrans that traps and kills parasitic worms. By deleting or increasing these genes, scientists found they control how the fungus makes sticky trap networks and how thick the trap walls are. This knowledge could help develop natural pest control products to protect plants and animals from harmful parasitic nematodes.

Fungal-derived ZnO nanoparticles functionalized with riboflavin and UDP-GlcNAc exhibit potent nematicidal activity against M. incognita

Scientists used a nematode-trapping fungus to create tiny zinc oxide particles that are highly toxic to root-knot nematodes, which damage crops worldwide. These nanoparticles are naturally coated with beneficial fungal compounds like riboflavin that enhance their pest-killing ability. The particles killed over 94% of nematodes in laboratory tests, offering a greener alternative to harsh chemical pesticides currently used in farming.

Biocontrol of Root-Knot Nematodes via siRNA-Loaded Extracellular Vesicles From a Nematophagous Fungus Arthrobotrys oligospora

Scientists developed a new way to control harmful root-knot nematodes that damage crops by using natural containers called extracellular vesicles from a fungus. These vesicles carry small RNA molecules that silence genes essential for nematode survival and reproduction. When tested on tomato plants, this fungal-based treatment reduced nematode damage by about 60% while promoting healthier plant growth, offering an eco-friendly alternative to chemical pesticides.

Functions of the Three Common Fungal Extracellular Membrane (CFEM) Domain-Containing Genes of Arthrobotrys flagrans in the Process of Nematode Trapping

Arthrobotrys flagrans is a fungus that acts as a natural pest controller by trapping and killing parasitic nematodes that damage crops and livestock. Scientists studied three key genes in this fungus that contain CFEM protein domains and found they are critical for forming sticky traps and controlling how deadly the fungus is to nematodes. The research shows that when certain CFEM genes are removed, the fungus produces stickier traps and kills more nematodes, while removing other CFEM genes has the opposite effect, providing insights for developing better biocontrol products.

A carnivorous mushroom paralyzes and kills nematodes via a volatile ketone

Scientists discovered that oyster mushrooms kill parasitic worms using a toxic gas stored in tiny bulb-shaped structures called toxocysts. The toxin is a common chemical called 3-octanone that ruptures the worms’ cell membranes, causing calcium to flood into cells and leading to rapid paralysis and death. This ‘nerve gas in a lollipop’ strategy could inspire new ways to control parasitic worms in agriculture and medicine.

Microbes vs. Nematodes: Insights into Biocontrol Through Antagonistic Organisms to Control Root-Knot Nematodes

mycolabadmin

This research explores natural and environmentally friendly ways to control harmful root-knot nematodes that damage crops worldwide. Instead of using chemical pesticides, the study examines how beneficial microorganisms and plant extracts can protect plants from these destructive pests. Impacts on everyday life: • Helps farmers produce healthier crops without harmful chemicals • Contributes to more sustainable and environmentally friendly agriculture • Supports food security by protecting crops from damaging pests • Reduces chemical residues in food products • Provides cost-effective alternatives for small-scale farmers
