Mycorrhizal network: a bidirectional pathway between green-leaved terrestrial orchids and pine trees

mycolabadmin

Underground fungal networks connect plant roots like a trading system. Scientists studied how three types of orchids and pine trees exchange carbon and nitrogen through these fungal connections. They found that each orchid species trades resources differently, with carbon consistently flowing from pine to orchids, but nitrogen movement varying by species. This shows that these underground networks are more complex and flexible than previously thought.

Omics approaches to investigate pre-symbiotic responses of the mycorrhizal fungus Tulasnella sp. SV6 to the orchid host Serapias vomeracea

This study examines how a fungus called Tulasnella responds to the presence of orchid plants before they physically touch each other. Using advanced techniques to measure gene activity and chemical composition, researchers found that the fungus activates growth and preparation genes when it senses the orchid nearby, suggesting the two organisms communicate through chemical signals even before making contact.

This study examines how a fungus called Tulasnella responds to orchids before they physically touch each other. Researchers grew the fungus near young orchid plants separated by a thin membrane and found that the fungus changed its genes and chemistry significantly, suggesting it somehow detected the orchid’s presence. The fungus increased production of proteins and fats, as if preparing for a partnership with the plant. These findings help us understand how plants and fungi communicate and begin their beneficial relationships.
