Isolation, functional and molecular characterization of arbuscular mycorrhizal symbionts from a "hot Spot" mediterranean site

Description: The present thesis aimed at characterizing native communities and single isolates of arbuscular mycorrhizal fungi (AMF) occurring in an experimental field representing a ?hot spot? of AMF diversity located inside the UNESCO Biosphere Reserve called ?Selva Pisana?, near San Piero a Grado (Pisa), a natural reserve on the east coast of Italy, in the northwest of Tuscany. The functional and molecular study of native communities provided new insights concerning the impact of AMF local species richness and community composition variations on host plant growth and nutrition. Moreover, the isolation of the largest possible number of AMF living in the protected experimental site, followed by functional and molecular characterization, represented a key step towards their potential use as natural sources of beneficial biofertilizers and bioenhancers for sustainable agriculture.
