Probably, in T. magnatum, this saprobic phase

is much more important than previously considered and as also suggested by Zampieri et al. [15]. Conclusions The results reported here demonstrate that the real-time PCR assay developed in this study can be an effective tool for quantifying T. magnatum in C646 concentration the soil and for monitoring the presence of this precious fungus, regardless of truffle production. This technique could be a useful tool to evaluate the “health” of see more natural and cultivated truffières and to assess the effect of different cultivation techniques. This aspect is particularly important because in natural truffières ascoma production is dispersed and depends on annual climatic conditions. Thus many years of survey are necessary to evaluate the effects of any new variable. Moreover, it is difficult

to assess truffle production in natural truffières because in Italy there is no control of truffle harvesting in the forests and numerous different truffle hunters may visit a single truffière in one day [1]. Real-time PCR will make it possible to carry out further studies on the spatial and seasonal changes in the quantity of T. magnatum mycelium in the soil to gain more knowledge on its biology and ecology. Methods Experimental truffières For this study four natural NVP-BSK805 research buy T. magnatum truffières located in four different Italian regions (Emilia Romagna, Tuscany, Abruzzo and Molise) were chosen on the basis of their high T. magnatum ascoma productivity. All these truffières are closed to the public so the scientific data on production collected are more meaningful. The Emilia Romagna experimental truffière is located in the Museum of the Bonifica Renana park at Argenta (Ferrara) (latitude 44° 37′ 10″ N, longitude 11° 48′ 55″ E, altitude 5 m asl). This truffière is representative of the natural T. magnatum production areas in the Po valley that are mostly located in private or public gardens and parks, the natural indigenous forest having been largely supplanted by agriculture. The putative T. magnatum host plants are poplar (Populus

nigra L.) and linden (Tilia vulgaris Hayne). The soil of the truffière is calcareous (10–25% of total CaCO3) with a pH MYO10 ranging from 7.9 to 8.3 in the different plots. The Tuscany, Abruzzo and Molise experimental truffières are representative of the natural T. magnatum truffières in the broad-leaved forests of the Apennine mountains of central-southern Italy. The Tuscan truffière is located at Barbialla nuova, Montaione (Florence) (latitude 43° 35′ 30″N, longitude 10° 50′ 55″ E, altitude 135 m asl). The putative host plants are hornbeam (Ostrya carpinifolia Scop.), poplar (Populus alba L.) and oaks (Quercus cerris L., Quercus petraea (Mattuschka) Liebl., Quercus ilex L.). The soil has a CaCO3 content ranging from 4 to 10% and a pH of 7.7-8.4.
