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

mycolabadmin

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.

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

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.

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.

Spatial and Temporal Variation in Fungal Endophyte Communities Isolated from Cultivated Cotton (Gossypium hirsutum)

mycolabadmin

This research explored the diverse community of beneficial fungi living inside cotton plants across Texas. These fungi, called endophytes, can potentially help protect plants from pests and diseases naturally. The study found that different types of fungi are present at different times of the growing season and in different plant parts, but the specific fungi present varied by location. This knowledge could lead to more sustainable farming practices. Impacts on everyday life: • Could reduce the need for chemical pesticides in cotton farming • May lead to more environmentally-friendly crop protection methods • Could help make cotton farming more sustainable and cost-effective • Provides natural alternatives for pest control in agriculture • Could improve cotton crop yields while reducing chemical inputs
