Effects of air pollutants on ectomycorrhizasFunded under: FP2-STEP
This review aims to discuss the effects of atmospheric pollutants on ectomycorrhizas and ectomycorrhizal fungi. The main questions considered are which atmospheric pollutants play a role, what are the effects on fungi, on trees and, to a lesser extent, on ecosystems, and what is known about the mechanism of the processes. The study is restricted to the influence of 'acid rain' and effects due to atmospheric deposition of SO(2), O(3), NO(x) and NH(3), although there can be effects on mycorrhizas of other types of pollution. The influence of nitrogen is included only when it originates from atmospheric deposition, not from fertiliser additions. However, nitrogen fertilisation is studied because it may give the same effects as nitrogen deposition resulting from air pollution. The review focuses mainly on the situation in the temperate zone in Western Europe. Only ectomycorrhizal fungi and ectomycorrhizal trees are considered as the reaction of Vesicular-Arbuscular mycorrhizal fungi and endomycorrhizal trees to air pollutants is quite different.
