Genetic diversity and mating type distribution in a Tuber borchii plantation
Tuber borchii is a truffle of excellent gastronomic quality. In 2016 the first experimental truffle orchard obtained inoculating the host trees with Tuber mycelial pure cultures began to produce. This plantation is located in the Bologna University farm at Cadriano (Bologna). It was established in 1997, the plants (oaks, pines and hazels) were inoculated with five different strains of T. borchii (1BO ,2292,Tb98, 2352 & 2364), alone and in mixture. The aim of this research is to study the actual genetic structure of T. borchii population in this truffle plantation using microsatillite markers and to study the mating type distribution of T. borchii in fruiting bodies, mycorrhizas and soil. The results which will be obtained in this study give new insights on truffle biology and help to understand how fertilization occurs in truffles between strains of different mating type.
