Resumen
Aim of study: In recent decades the cultivation of the black truffle Tuber melanosporum has expanded across all the Mediterranean-climate regions, but also to other regions outside the European standard for the species. We aim to describe the current extent of T. melanosporum cultivation.Area of study: Tuber melanosporum plantations in Europe, the Mediterranean basin, Australia, New Zealand, China, America and South Africa.Material and Methods: The socioeconomic impact of T. melanosporum cultivation, the way in which the current situation has been achieved and the knowledge needed for its progress are reviewed.Research highlights: T. melanosporum has been successfully cultivated in several countries outside its natural area, but many practices are still empirical and thus yields cannot be guaranteed. The recent advances in molecular techniques and genome science are helping to overcome some of the difficulties traditionally constraining truffle research. The role of truffles as a transitional element between agricultural and forestry activities makes its cultivation a paradigm of sustainable rural development.Keywords: Tuber melanosporum; Europe; Australia; New Zealand; Chile; USA.
