Inside a large greenhouse at the University of Kansas, Professor Liz Koziol and Dr Terra Lubin tend rows of sudan grass in individual plastic pots. The roots of each straggly plant harbor a specific strain of invisible soil fungus. The shelves of a nearby cold room are stacked high with thousands of plastic bags and vials containing fungal spores harvested from these plants, then carefully preserved by the researchers.
The samples in this seemingly unremarkable room are part of the International Collection of Vesicular Arbuscular Mycorrhizal Fungi (INVAM), the world’s largest living library of soil fungi. Four decades in the making, it could cease to exist within a year due to federal budget cuts.
