Truffle Brules Have an Impact on the Diversity of Soil Bacterial Communities

Background: The development of Tuber melanosporum mycorrhizal symbiosis is associated with the production of an area devoid of vegetation (commonly referred to by the French word 'brule') around the symbiotic plants and where the fruiting bodies of T. melanosporum are usually collected. The extent of the ecological impact of such an area is still being discovered. While the relationship between T. melanosporum and the other fungi present in the brule has been assessed, no data are available on the relationship between this fungus and the bacteria inhabiting the brule.
