Phys.org / Underground fungal networks come into 3D view without disturbing plant roots

Symbioses between plants and fungi are essential for most plants. Fungal structures known as mycorrhizae extend the area from which plants can draw water and nutrients from the soil. In return, plants supply the fungi with ...
