This research examined the relationship between trees and beneficial fungi in a tropical forest in Guyana. The scientists discovered that most fungi were generalists, forming partnerships with multiple tree species rather than specializing on just one type of tree. They also found a potentially new species of fungus that may exist nowhere else in the world. This work helps us understand how plants and fungi work together in tropical forests. Impacts on everyday life: • Helps explain how forests maintain soil health and nutrient cycling • Provides insights for forest conservation and restoration efforts • Advances our understanding of plant-fungal partnerships that could benefit agriculture • Demonstrates the importance of preserving unique ecosystems that may contain undiscovered species • Could lead to discovery of new fungi with potential applications in medicine or industry
