ABOVE: Mycorrhizal fungi’s hyphal network stained in purple

In a study published yesterday (June 6) in Current Biology, scientists tracked the movement of phosphorous particles between fungi and plant roots in a symbiotic relationship. The researchers set up petri dishes with three sections: one with few nutrients, one with plentiful nutrients, and one where the plant roots grew. The fungi were able to grow through all three sections and moved nutrients to where demand from the plant was higher, according to the report.
