Mushrooms of the genus Mycena not only live off of dead trees and plants, but also young, healthy trees and plants.

Marine biologists have discovered the remnants of ancient RNA viruses embedded in the DNA of symbiotic organisms living inside reef-building corals.

Two genes are indispensable for allowing plants to defend themselves against fungal attack on land, research shows.

The best-known ergot alkaloid is LSD. Finding the compounds in morning glories could lead to psychedelic drugs for mental and physical conditions.

Microscopic algae may evolve in tandem with the corals they inhabit, so each partner is fine-tuned to meet one another's needs, according to a new study.

Fish that dine on corals may pay it forward with their poop, which is jam-packed with all kinds of algae coral reefs depend on for survival.

When food becomes scarce, sea anemones turn to their Plan B: Relying on their symbiotic relationship with algae under their skin.

New insights into how ants and bacteria became a single organism may lead to a better understanding of the origin of complex organisms, researchers report.

New research sheds light on the genetic mechanisms behind how bioluminescent bacteria compete to live symbiotically with the Hawaiian bobtail squid.

"In terms of ecosystem function, particularly buffering the atmosphere against climate change, ectomycorrhizal fungi are among the last microbes you want to lose."
