Abstract

Different methodological tools have been developed to trace truffles in soil from fruiting body collections and mycorrhiza morphotyping to recent highsensitive molecular techniques able to detect specific truffle DNA markers in the soil Recent findings in disclosing the biological cycle of truffles based on molecular research have represented a significant step forward toward a rational cultivation On the other hand the relationships among the different phases of the symbiosis mycorrhizas extraradical mycelium and fruiting body formation remain unsolved The detection and quantification of truffle mycelium in the soil along the truffle development might be the key to understand the processes leading to fertilization and fruiting body formation Also the knowledge of soil mycelium dynamics at temporal and spatial scales is necessary to evaluate the fungal responses to environmental changes and to develop appropriate management techniques to ensure fungal persistence and regular fruiting body productionFinancial support for part of the studies presented by the authors was provided by the Spanish Ministry of Economy MINECO grant AGL201240035C0303 and the Generalitat de Catalunya AGAUR Innovative Pilot Project AAM/259/2013 The UMR1136 is supported by a grant overseen by the French National Research Agency ANR as part of the Investments for the Future program ANR11LABX000201 Lab of Excellence ARBRE
