Mycorrhizal ecology

The symbiosis between fungi and plants is ancient. Most plants form mycorrhizas, yet we know surprising little on the biotic and abiotic factors shaping the interaction between plants and fungi. The lab explores a wide range of topics on mycorrhizal ecology and is always looking to open new avenues to reveal the coolness of mycorrhizas.
