This text deals with the most widespread root symbiosis, arbuscular mycorrhizas, an essential component of soil/plant systems occurring in the majority of plant species in natural agro-ecosystems. The book is intended to aid the environmental researcher in finding relevant methods quickly, and as a general reference work should be useful to field ecologists, laboratory biologists and other workers in plant biology and soil microbiology. The volume contains advances in (i) the field of the development of biomolecular methods adapted to arbuscular mycorrhizal fungi; (ii) the promotion of...
