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.

Halotolerant Endophytic Fungi: Diversity, Host Plants, and Mechanisms in Plant Salt–Alkali Stress Alleviation

mycolabadmin

Salty and alkaline soil is destroying farmland worldwide, but special fungi living inside plants can help crops survive these harsh conditions. These fungi work like a team with plants, producing protective substances and helping plants manage salt and reduce damage from stress. Scientists reviewed 150 studies and found these fungi boost crop yields by 15-40%, offering a natural way to farm on degraded land without more chemicals.

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.

Digging into the evolutionary history of the fungus-growing-ant symbiont, Escovopsis (Hypocreaceae)

mycolabadmin

Researchers studied fungi called Escovopsis that live in ant colonies and interact with the fungi that ants farm for food. By examining 309 fungal samples from across Central and South America, they discovered that these fungi originated 57 million years ago but only started living with the ants about 38 million years ago. Over time, Escovopsis evolved to grow faster and reproduce more efficiently, likely helping it survive in the ant colony environment.

Alliance Between Conifer Trees and Endophytic Fungi Against Insect Defoliators

Tiny fungi living inside white spruce trees help protect them from destructive budworm insects in two ways: the fungi directly produce toxic substances that kill or harm the budworms, and they also trigger the trees to produce more of their own natural chemical defenses called terpenes. Scientists found that spruce trees with more of these helpful fungi in their leaves were better protected against budworm damage. This discovery shows that trees don’t fight pests alone but partner with beneficial fungi as part of their defense system.
