Alliance Between Conifer Trees and Endophytic Fungi Against Insect Defoliators

mycolabadmin

This study discovered that special fungi living inside white spruce trees help protect the trees from damaging insects called budworms. These fungi produce toxic substances and smelly compounds that kill or repel the budworms. When researchers increased the amount of these beneficial fungi in young spruce trees, the trees produced higher levels of protective chemicals called terpenes. This research shows that the relationship between spruce trees, fungi, and insects has evolved together over time, with fungi playing a crucial role in keeping trees healthy.

Alliance Between Conifer Trees and Endophytic Fungi Against Insect Defoliators

mycolabadmin

Scientists discovered that beneficial fungi living inside white spruce trees help protect the trees from damaging spruce budworm insects. These fungi work in two ways: they produce toxic substances that poison the insects, and they help trees produce protective chemical compounds called terpenes. In greenhouse experiments, trees with more of these beneficial fungi had significantly more protective chemicals in their leaves. This natural partnership between trees and fungi represents millions of years of evolution working together to fight off pests.

Alliance Between Conifer Trees and Endophytic Fungi Against Insect Defoliators

Researchers discovered that helpful fungi living inside white spruce needles protect the trees from damaging budworm insects. These fungi work in two ways: they directly poison the insects that try to eat the needles, and they also encourage the trees to produce more of their own chemical defenses. This partnership between fungi and trees demonstrates an important co-evolutionary relationship where all three organisms—fungi, trees, and insects—influence each other over time.

Isolation, (bio)synthetic studies and evaluation of antimicrobial properties of drimenol-type sesquiterpenes of Termitomyces fungi

mycolabadmin

Termite colonies farm a fungus called Termitomyces for food in an ancient partnership. Scientists discovered that the mushrooms produced by this fungus release distinctive chemical signals, particularly a compound called drimenol. By isolating and synthesizing these compounds, researchers found they have antimicrobial properties and may play a role in communicating between termites and their fungal crop or protecting mushrooms from infection.
