Despite their importance in the host tree\u2019s physiology and in the functioning of the ectomycorrhizal symbiosis, detailed studies on ectomycorrhiza-associated bacterial community composition and their temporal dynamics are rare. Our objective was to investigate the composition and dynamics of\u00a0<em class=\"EmphasisTypeItalic \">Tuber melanosporum<\/em>ectomycorrhiza-associated bacterial communities from summer to winter seasons in a\u00a0<em class=\"EmphasisTypeItalic \">Corylus avellana<\/em>\u00a0tree plantation. We used 16S ribosomal RNA (rRNA)-based pyrosequencing to compare the bacterial community structure and the richness in\u00a0<em class=\"EmphasisTypeItalic \">T. melanosporum<\/em>\u2019s ectomycorrhizae with those of the bulk soil. The\u00a0<em class=\"EmphasisTypeItalic \">T. melanosporum<\/em>\u00a0ectomycorrhizae harbored distinct bacterial communities from those of the bulk soil, with an enrichment in Alpha- and Gamma-proteobacteria. In contrast to the bacterial communities of truffle ascocarps that vastly varies in composition and richness during the maturation of the fruiting body and to those from the bulk soil,\u00a0<em class=\"EmphasisTypeItalic \">T. melanosporum<\/em>\u00a0ectomycorrhiza-associated bacterial community composition stayed rather stable from September to January. Our results fit with a recent finding from the same experimental site at the same period that a continuous supply of carbohydrates and nitrogen occurs from ectomycorrhizae to the fruiting bodies during the maturation of the ascocarps. We propose that this creates a stable niche in the ectomycorrhizosphere although the phenology of the tree changes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Temporal changes of bacterial communities in the Tuber melanosporum ectomycorrhizosphere during ascocarp development.\u00a0A Deveau, S Antony-Babu, F Le Tacon, C Robin, P Frey-Klett, S Uroz.
