Effect of the mycorrhizal symbiosis time in the antioxidant activity of fungi and Pinus pinaster roots, stems and leaves [PDF]

open access: yes, 2012
The ectomycorrhizal (ECM) symbiosis that develops between the roots of host trees and the soil ECM fungi is an important factor towards the survival, health and growth of these trees, as it stimulates their water and nutrient uptake.
