Arbuscular mycorrhiza fungi (AMF) which form a mutualistic symbiosis with most terrestrial plants are not only important for natural ecosystems, but also for agricultural production. The aim of this study is to characterize fungal populations at different geographic scales in order to better understand the processes influencing AMF taxonomic and functional diversity and to determine the environmental factors affecting AMF populations, especially in the context of agricultural management. The mitochondrial large subunit gene of ribosomal RNA will be used as molecular marker to resolve population structure of Rhizophagus irregularis (formerly known as Glomus intraradices). Different sampling approaches are planned, combining sampling of geographically distant sites across France and field sites affected by different environmental factors such as disturbance, fertilization and agricultural management".
