Arbuscular Mycorrhizal Fungi and Metal Phytoremediation

Ecophysiological Complementarity in Relation to Environmental Stress

Patrick Audet

Recent investigative interests focusing on plants and their allied soil-symbionts would suggest an important and multilateral impact of soil microbes in plant nutrient uptake and the regulation of soil nutrient availability. Focusing especially on the arbuscular mycorrhizal (AM) fungi, this chapter examines the primary mechanisms by which plant–soil interactions shape plant stress tolerance in relation to metal stress (i.e., from deficiency to toxicity conditions), and further outlines how these properties could be applied toward the phytoremediation of metal-polluted environments. Core mechanisms ...
